How to open settings app programmatically?

Question

I'm using swift with ios 8.3. I want to open settings app from my application. I know that using the code

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

will open my app settings. But I don't want to open my app settings. I just want to open the settings app and stay in the main page. If possible, navigate to "Cellular". Is there any way to acheive this?

Answer 1

Try this.

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

Xcode 11.5 - iOS > 10

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]

prefs:root=General&path=About
prefs:root=General&path=ACCESSIBILITY
prefs:root=AIRPLANE_MODE
prefs:root=General&path=AUTOLOCK
prefs:root=General&path=USAGE/CELLULAR_USAGE
prefs:root=General&path=Bluetooth
prefs:root=General&path=DATE_AND_TIME
prefs:root=FACETIME

prefs:root=TWITTER
prefs:root=General&path=USAGE
prefs:root=VIDEO
prefs:root=General&path=Network/VPN

YES, They made changes in iOS 10, Please change "prefs:" to "App-Prefs:"

guard let profileUrl = URL(string:"App-Prefs:root=General&path=ManagedConfigurationList") else {
    return
}

if UIApplication.shared.canOpenURL(profileUrl) {
    UIApplication.shared.open(profileUrl, completionHandler: { (success) in
        print(" Profile Settings opened: \(success)")
    })
}
