Stop UIView from roating into landscape

Question

I have a UIView thats inside a navigation controller, I am trying to prevent this view from going into Landscape however the method I am trying to use never fires.. code is below any help would be greatly appreciated..

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    if(interfaceOrientation == UIInterfaceOrientationLandscapeRight)
    {
        return NO;
    }
    else if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
    {
        return NO;
    }
    return NO;
}

is that method in a view or a view controller? – Leatrice

Answer 1

You should set return NO; for the parent navigation controller or on a UIViewController, not a UIView.

Also, this works just the same with less code:

iOS 5.x

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

iOS 6

As of iOS 6, shouldAutorotateToInterfaceOrientation: is deprecated. If the view controller does not override the supportedInterfaceOrientations method, UIKit obtains the default rotations from the app delegate or the app’s Info.plist file.

You will need to use:

- (NSUInteger)supportedInterfaceOrientations NS_AVAILABLE_IOS(6_0);

As I remarked in my response, always returning NO is considered improper and (last I checked) triggers a run-time warning. – Inequity

sorry this is not working for me.. as from another answer I read that its on invoked on a view but on the viewcontroller. I have a UIView in InterfaceBuilder which is linked to the fileOwner as a view.. but I just dunno what else to look for to get this thing to stop rotating. – Anew

Place this code on your parent UINavigationController, as explained, shouldAutorotateToInterfaceOrientation: is apart of the UIViewController class and will not work on a UIView. – Inwardly

right.. I understand now.. I should also tell you that I was only wanting to prevent this view from rotating not every view in my NavigationController.. is there a way to achieve this? – Anew

Yes, you can set a BOOL option to see if the view is visible. If it is, then disable rotation. So when you show the view, set something like myViewIsShowing = YES;. if (myViewIsShowing) /*do not rotate */; – Inwardly

Okay I'm having difficulty here :( I know that you want me to place the code on my parent UINavController, however I am using a master-detail Application, the masterView is simply a UIViewController of a uiview, the NavigationController is declared in the appDelegate.. I'm kinda lost as to where I can put this code to get it to work.. i have tried everywhere and still no success.. – Anew

You should probably read the Apple docs on both UIViewController and UINavigationController to get a better understanding. – Inwardly

Have you used the template "master-detail Application"? – Anew

On many occasions. The template you use makes no difference. The classes still require the same methods. – Inwardly

humor me, start your own "master-detail Application" thats standard in the apple templates when it loads go to masterViewController.m in there you will see the exact same method you have suggested above, change it from != UIInterfaceOrientationPortraitUpsideDown to what you have suggested == UIInterfaceOrientationPortrait then run it on a device and see what happens.. the damn thing is broken.. unless I am going absolutely crazy, I have tried this twice on my project which is very similar to the template just with few alterations and then on a completely fresh template. – Anew

I don't understand the syntax : - (NSUInteger)supportedInterfaceOrientations NS_AVAILABLE_IOS(6_0);. Is that really what I have to type ? If it is, it's the 1st time I see that. – Hydrothorax

No, NS_AVAIL just tells you that it's available only in iOS 6. It's from the Apple docs. – Inwardly

Answer 2

Another option is modifying Deployment Info.

Answer 3

This method needs to be implemented in a UIViewController instance, not a UIView.

Also, you are in fact returning NO for all orientations, which is incorrect. You need to return YES for at least one orientation (most commonly UIInterfaceOrientationPortrait).

woopsie!!! i had it at yes at one point and in my frantic state of trying to find a solution must have changed that for some weird reason. – Anew
