Update on 11-Oct-2016:
It won't work in iOS10 anymore. So far I haven't found any workaround. If you guys have any solution please let me know. thanks.
======================================
if the iOS version <= iOS9, you need set URL types:
You can do in this way:
let url:NSURL! = NSURL(string : "prefs:root=")
UIApplication.sharedApplication().openURL(url)
I have a demo on github: http://github.com/zhihuitang/SettingDemo.git
And you can find all available URLs as follows:
http://iphonedevwiki.net/index.php/Preferences.app
Preferences app registers a private URL scheme, prefs:, the list below details opening specific views 1[2]
