How to open settings from my iPad application (Objective-C) [duplicate]

Answer 1

Apple no longer allows developers to open the Settings application from within their apps (iOS 5.1 and later).

EDIT

According to @Mike's comment below, this can be done in iOS 8+

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

Using this prior to iOS 8 will result in a crash, however.
