NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];

if ([[UIApplication sharedApplication] canOpenURL:url]) {

    [[UIApplication sharedApplication] openURL:url];

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Restrictions"]];
