How to open general settings (not in the app settings) from the app in iOS 8?

Question

I know about this

    if (&UIApplicationOpenSettingsURLString != NULL) {
    NSURL *appSettings = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
    [[UIApplication sharedApplication] openURL:appSettings];
} 

But I wanna know if its possible to go to the general settings. I need users to enable the keyboard but landing in the app settings confused many users. Any suggestions to open the general settings and even if possible the keyboards section?

Answer 1

You cannot open system apps in iOS. You can show them the path to the message though.

'Settings->General->Keyboard' etc in a modal whenever you wish to display this information to the user.

Answer 2

从iOS 10开始，可以使用“App-Prefs：root”URL：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"App-Prefs:root"]];
