How to Open Keyboard's settings screen programmatically in iOS 10?

This code is not working in iOS 10

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

and added URL Scheme

Answer 1

It looks like this functionality has been disabled in iOS 10. I believe that https://developer.apple.com/library/content/qa/qa1924/_index.html is no longer valid. I checked several top keyboard apps and they have either been updated to no longer have a direct link to the preferences, or have a non-working button.

Answer 2

is work in iOS 10+

NSURL *keboardURL = [NSURL URLWithString: @"App-Prefs:root=General&path=Keyboard/KEYBOARDS"];
[[UIApplication sharedApplication] openURL:keyboardURL];

key points:

@"App-Prefs:root=General&path=Keyboard/KEYBOARDS"
