Opening the Settings app from another app

Asked 13/4, 2011 at 21:10 Answered 10/7, 2023 at 10:32

Solved ios objective-c iphone application-settings appsettings

Okay, I know that there are many question about it, but they are all from many time ago.

So. I know that it is possible because the Map app does it.

In the Map app if I turn off the localization for this app, it send me a message, and if I press okay, the "Settings App" will be open. And my question is, how is this possible? How can I open the "Setting app" from my own app?

Basically I need to do the same thing, if the user turn off the location for my app, then I'll show him a message saying something that will open the "Setting app"

You can open settings app programmatically in iOS8(but not in lower versions of iOS).code below in answers. – Stifling 4/8, 2014 at 8:2

As mentioned by Karan Dua this is now possible in iOS8 using UIApplicationOpenSettingsURLString see Apple's Documentation.

Example:

Swift 4.2

UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!)

In Swift 3:

UIApplication.shared.open(URL(string:UIApplicationOpenSettingsURLString)!)

In Swift 2:

UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)

In Objective-C

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

Prior to iOS 8:

You can not. As you said this has been covered many times and that pop up asking you to turn on location services is supplied by Apple and not by the App itself. That is why it is able to the open the settings application.

Here are a few related questions & articles:

If you need a more authoritative answer, you might try asking on the Apple Developer forums <developer.apple.com/devforums> or filing a bug at <developer.apple.com/bugreporter> — if it's a known issue it should come back as "behaves correctly" or a duplicate of the original bug. – Theodor 15/8, 2011 at 20:40

Not possible is rarely true in the field of programming. – Natalienatalina 29/3, 2013 at 6:52

I agree if you are willing to bend/break the rules. – Allheal 29/3, 2013 at 11:36

This is now possible in iOS 8 using [NSURL URLWithString:UIApplicationOpenSettingsURLString] – Phyto 27/10, 2014 at 14:44

@Allheal This solution is not working for iOS 10 . I am working on Xcode 8, swift 3. Any alternate solution please? – Dari 23/9, 2016 at 4:31

@joe i have worked in iOS 10. its not Works. if any other solution please update your answer. – Carew 19/10, 2016 at 5:55

I think, they still work with Extensions. Ex app is Magic Launcher in Appstore. – Standstill 21/10, 2016 at 18:8

in swift 3 - UIApplication.shared.openURL(URL(string:UIApplicationOpenSettingsURLString)!) – Desex 4/11, 2016 at 15:6

Be wary of using this method. I used it and a few months later my app got rejected with the following message from Apple: Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change. Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store. – Sheets 31/8, 2018 at 9:8

@Nick Kirsten did you mean this answer or the answer bellow ?, I can't see any "prefs:root" phrase in the current answer. Also, what did you do instead ? – Lacerta 1/10, 2020 at 12:51

openSettingsURLString is a public API, see documentation: developer.apple.com/documentation/uikit/uiapplication/… – Conoid 30/6, 2021 at 15:2

From @Yatheeshaless's answer:

You can open settings app programmatically in iOS8, but not in earlier versions of iOS.

Swift:

   UIApplication.sharedApplication().openURL(NSURL(string:UIApplicationOpenSettingsURLString)!)

Swift 4:

if let url = NSURL(string: UIApplicationOpenSettingsURLString) as URL? {
    UIApplication.shared.openURL(url)
}

Swift 4.2 (BETA):

if let url = NSURL(string: UIApplication.openSettingsURLString) as URL? {
    UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

Objective-C:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

Stifling answered 25/7, 2014 at 9:54 Comment(6)

This appears to open your app's section of the Settings app. Users will have to hit Back a few times to see the main screen of Settings. – Incompletion 25/9, 2014 at 18:41

Small correction.. [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]]; – Recount 8/10, 2014 at 13:32

@Recount The above line is directing to app private settings. Is there any way to direct to privacy section of the device settings? Please comment if you know. This redirection is possible, as I found it in maps app where it directs to location settings in privacy section. – Checkoff 10/10, 2014 at 15:6

Not sure if it's possible, Apple apps often do things that we can't by using private APIs, the Google Maps app just goes to the App Settings not Location Services. – Recount 15/10, 2014 at 14:35

Small Swift correction: UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString)!) – Surroundings 11/11, 2014 at 13:57

@PavanKotesh- Yes but the app settings will have what you need permission for, in my case i needed access to contacts, which do appear in app settings with above code. – Quaint 2/2, 2016 at 10:40

YES!! you can launch Device Settings screen, I have tested on iOS 9.2

Step 1. we need to add URL schemes

Go to Project settings --> Info --> URL Types --> Add New URL Schemes

Step 2. Launch Settings programmatically Thanks to @davidcann

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];

Also we can launch sub-screens like Music, Location etc. as well by just using proper name

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=MUSIC"]];

See this full name list here shared by Henri Normak

Update:

As per the comment everyone wants to know what happens after this change to my application submission status?

So YES!! I got successful update submission and application is available on store without any complain.

Just to confirm, I Just downloaded this morning and disabled Location services, and then started the app, which asked me for location permission and then my alert popup was there to send me on settings -> location services page --> Enabled --> That's it!!

![NOTICE: Your app might be rejected ... even if it's approved it can be rejected in future version if you use this method...]4

Thanks, works for me, on iOS 6 and 7, too. Did you try to get it through Apple's review process yet? – Uncounted 17/3, 2016 at 9:34

@Uncounted I will let you know, because presently I have pushed for beta testing. – Essie 17/3, 2016 at 9:59

Hey @RDC, have you got any news about the review of your app? – Balsa 24/3, 2016 at 7:29

@RDC did your app pass the App Review process? – Dirty 4/4, 2016 at 5:19

iOS 9.3. Worked like a charm. I even see "Back to [my app name]" inside the settings app. Surely, this is supported because I see plenty of other apps that do this kind of thing! – Coextend 8/4, 2016 at 21:28

I am using that and it failed the submission to app store? Anyone else had the same issue or a work around it? – Vitale 26/4, 2016 at 20:35

@RDC Did Apple approved the build with "prefs" private APIs? – Christen 29/5, 2016 at 13:30

@Christen YES!! The application has been approved and available on store. – Essie 30/5, 2016 at 6:7

From the feedbacks in 2012, using the code 'prefs:' to be rejected, but from this feedback as now in 2016, he says 'approved', Then, hope he be right. – Dalton 27/6, 2016 at 5:52

I think, they still work with Extensions. Ex app is Magic Launcher in Appstore. – Standstill 21/10, 2016 at 18:9

On iOS 10, the new url is not "prefs:root=...." but "App-Prefs:root=...". – Thea 28/2, 2017 at 16:17

Your app might be rejected ... even if it's approved it can be rejected in future version if you use this method... – Haletky 9/4, 2019 at 5:51

Do not do step 1. That is where you define the custom URL schemes that open your own app. – Hinshelwood 10/7, 2023 at 13:28

Seems like you can use the prefs:<area> URL to open the settings and go to specific areas. Apple could change these and break your app so always check if you can open them first.

this is not working for iOS 14 ..always showing settings instead of path mentioned. any workaround ? – Nemhauser 30/3, 2021 at 14:14

yes, i have also same issue with iOS 14 but in my case it is resolved when i remove root prefix. for example instead of "prefs:root=Privacy&path=LOCATION" i have ued "App-prefs:Privacy&path=LOCATION" and it works in iOS 14. – Mowbray 25/6, 2021 at 4:56

Does Apple no longer reject the app if we use such configurations? – Read 13/12, 2022 at 17:32

@Read did you find an answer to this? I also need to know if they still reject apps that do this (since I can find examples of current apps in App Store that clearly do it). – Askja 15/1, 2024 at 12:20

~~You can use this on iOS 5.0 and later:~~ This no longer works.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];

Indemonstrable answered 15/10, 2011 at 16:55 Comment(8)

Son of a gun, that actually works! I can't find any documentation reference to this. Do you have one? What the behavior of this code under iOS4? Other than failure, what happens? Nothing? – Leacock 18/10, 2011 at 19:14

@MarkGranoff No, it seems to be technically undocumented, but it's not as bad as a normal undocumented API, since it's just a URL Scheme. You can check for it with canOpenURL: first. Also, there's a thread about it here: devforums.apple.com/message/543818 – Indemonstrable 18/10, 2011 at 20:23

Right! Excellent points. That DevForum thread suggested that undocumented == private API, which means: don't use it (until it's documented. :-) – Leacock 18/10, 2011 at 20:29

You can get to different areas in settings according to this article. For example this URL will take you to Bluetooth settings prefs:root=General&path=Bluetooth – Searles 10/11, 2011 at 14:2

I got an application rejected for using private API because I was opening the url: @"prefs:root=Brightness". Usually, un-documented means private. – Alluvium 5/1, 2012 at 18:23

Apple has stated that this wasn't a public API, and is no longer supported. There is a bug filed on this issue, number 11253669. – Patinated 8/5, 2012 at 4:57

I just saw that this works in Strava app. Turn off Bluetooth & then turn it on in app. Then it asks to got to settings app & it goes directly to Bluetooth settings. This is for iOS5.1. Is there a way to find out what scheme they are using? – Charily 1/12, 2012 at 0:57

@Charily see #15682664 – Intrigant 10/8, 2013 at 9:55

iOS 10 update

Apple changed the method to open async on the main thread. However, from now it is only possible to open the app settings in native settings.

[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];

iOS 9 update

It is now possible to go directly to sub-settings menu. However, a URL scheme has to be created. It can be done using two ways:

XCode - You will find it in Target, Info, URL Scheme. Then, just type prefs.
Directly adding to *-Info.plist. Add the following: <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleTypeRole</key> <string>Editor</string> <key>CFBundleURLSchemes</key> <array> <string>prefs</string> </array> </dict> </array>

Then the code:

Swift

UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=General&path=Keyboard")!)

Objective-c

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Keyboard"]];

@MarkPeters, did you figure out a way yet? It could be of great help. Thanks. – Battery 29/9, 2016 at 10:56

No, I haven't. I still don't know if it is an iOS bug or if Apple just removed the feature. – Astronomy 30/9, 2016 at 23:1

I think, they still work with Extensions. Ex app is Magic Launcher in Appstore. – Standstill 21/10, 2016 at 18:9

Do not perform step 2. CFBundleURLTypes is where you define the custom URL schemes used to open your own app. – Hinshelwood 10/7, 2023 at 13:30

In Swift 3 / iOS 10+ this now looks like

if let url = URL(string: "App-Prefs:root=LOCATION_SERVICES") {
    UIApplication.shared.open(url, completionHandler: .none)
}

Huntingdonshire answered 29/3, 2017 at 9:48 Comment(4)

how to get to notification screen? because if let url = URL(string: "App-Prefs:root=NOTIFICATIONS_ID&path=io.artup.artup") { if #available(iOS 10.0, *) { UIApplication.shared.open(url, completionHandler: .none) } } but i went to notification in iPhone 6 not in iPhone 7 plus? – Firepower 13/7, 2017 at 7:41

This will get your app rejected. They put it under use of private API. – Nellienellir 24/8, 2018 at 8:59

I have got rejected my app, using this "App-Prefs:root" – Cumbersome 9/10, 2018 at 21:21

Just emphasize what others mentioned here, don't use this method, it'll get your app rejected. Repeatedly submitting app with such will get your developer account closed. – Grazing 8/1, 2019 at 2:19

In Swift 3 all I needed is this (here for example redirect to my app notifications):

if let url = URL(string: "App-Prefs:root=NOTIFICATIONS_ID&path=your app bundleID") {
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, completionHandler: .none)
    } else {
        // Fallback on earlier versions
    }
}

Source: phynet gist.

This worked with me only when settings is in background. It will redirect you to your app notification settings but if settings wasn't running in the background it will just redirect you to notification settings in general.

Babylonian answered 13/4, 2017 at 11:36 Comment(0)

Swift 3:

guard let url = URL(string: UIApplicationOpenSettingsURLString) else {return}
if #available(iOS 10.0, *) {
  UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
  // Fallback on earlier versions
  UIApplication.shared.openURL(url)
}

Timeout answered 21/6, 2017 at 2:12 Comment(0)

UIApplicationOpenSettingsURLString this will only work if you have previously allowed for any permission. For example Location, Photo, Contact, Push notification access. So if you have not such permission(s) from the user:

If iOS 10 or above,

It will open the Settings but then crash it. The reason, there's nothing in settings for your app.

Below code will open your application settings inside the iOS Setting.

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL:url];
}

Due to device unavailability, I couldn't check this on iOS < 10.

Also, I could find below code from some gist and it works fine on iOS 10 as well. But I am not sure if this will approve by Apple review team or not.

Olcott answered 17/1, 2017 at 11:17 Comment(0)

As openURL(_:) is deprecated after iOS 10.0, use open(_:options:completionHandler:) instead.

if let settingsUrl = URL(string: UIApplication.openSettingsURLString)  {
        UIApplication.shared.open(settingsUrl, options: [:]) { completed in
             if !completed {
                 print("Failed opening")
             }
        }
}

Companionate answered 9/11, 2021 at 9:8 Comment(0)

You can use the below code for it.

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

Valentino answered 31/5, 2016 at 12:50 Comment(0)

Tested with iOS 10. Working

NSArray* urlStrings = @[@"prefs:root=WIFI", @"App-Prefs:root=WIFI"];
for(NSString* urlString in urlStrings){
NSURL* url = [NSURL URLWithString:urlString];
if([[UIApplication sharedApplication] canOpenURL:url]){
    [[UIApplication sharedApplication] openURL:url];
    break;
}
}

Happy Coding :)

Is that so, But this line of code will directly take you to the desired location – Imprudent 5/9, 2018 at 13:24

Yes it will get you there. I'm not saying it doesn't work, I'm just pointing out that it will get you rejected during app review. "prefs:root" is a private url scheme according to what the review team told us. (You might get lucky and they don't notice for a while, we had the feature in for a while and passed several reviews before the reviewer noticed it) – Nellienellir 5/9, 2018 at 16:21

SWIFT 4.0

'openURL' was deprecated in iOS 10.0: Please use openURL:options:completionHandler: instead

UIApplication.shared.open(URL.init(string: UIApplicationOpenSettingsURLString)! , options: [:], completionHandler: nil)

I prefer to open setting in a safer way,

if let settingUrl = URL(string:UIApplicationOpenSettingsURLString) {

    UIApplication.shared.open(settingUrl)
}
else {
    print("Setting URL invalid")
}

From iOS 16, you can use openSettingsURLString

if let url = URL(string: UIApplication. openSettingsURLString) {
    await UIApplication.shared.open(url)
}

Swift You can use following function to open Settings App with Bluetooth Page

func openSettingsApp(){
    if let settings = NSURL(string: "prefs:root=Bluetooth") {
        UIApplication.sharedApplication().openURL(settings)
    }
}

Again this would not open the App's Settings. This would open settings app with Bluetooth as this is deep linking to bluetooth.

To add to accepted answer: (from apple developer documentation) "When you open the URL built from this string (openSettingsURLString), the system launches the Settings app and displays the app’s custom settings, if it has any." So, if you want to open settings for your app, create your own Settings.bundle.

Add this to your class,

 public class func showSettingsAlert(title:String,message:String,onVC viewController:UIViewController,onCancel:(()->())?){
            YourClass.show2ButtonsAlert(onVC: viewController, title: title, message: message, button1Title: "Settings", button2Title: "Cancel", onButton1Click: {
                if let settingsURL = NSURL(string: UIApplicationOpenSettingsURLString){
                    UIApplication.sharedApplication().openURL(settingsURL)
                }
                }, onButton2Click: {
                    onCancel?()
            })
        }

 public class func show2ButtonsAlert(onVC viewController:UIViewController,title:String,message:String,button1Title:String,button2Title:String,onButton1Click:(()->())?,onButton2Click:(()->())?){
            dispatch_async(dispatch_get_main_queue()) {
                let alert : UIAlertController = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)

                alert.addAction(UIAlertAction(title: button1Title, style:.Default, handler: { (action:UIAlertAction) in
                    onButton1Click?()
                }))

                alert.addAction(UIAlertAction(title: button2Title, style:.Default, handler: { (action:UIAlertAction) in
                    onButton2Click?()
                }))

                viewController.presentViewController(alert, animated: true, completion: nil)
            }
        }

Call like this,

YourClass.showSettingsAlert("App would like to access camera", message: "App would like to access camera desc", onVC: fromViewController, onCancel: {
  print("canceled")
})
