Possible Duplicate:
Opening the Settings app from another app
Is there a way to direct the user to the Settings.app whenever I show a UIAlertView prompt? This prompt alerts the user that his location services is turned off and I want the user to open the Settings.app when he taps the button inside my UIAlertView.
UPDATE: I'm looking for a similar code stated here:

回答1:
iOS 8 and iOS 9
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
There is no way to do this.
Because till now (11th Jan 2013) there is no url scheme available for settings app.
iOS 6
You can't do this on iOS 6.
iOS 5 and below (< iOS 5.1)
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];
