从警报中启动设置
我想从下面的警报中启动设置应用程序：
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {NSString * title = [alertView buttonTitleAtIndex：buttonIndex];
if([title isEqualToString:@"Ok"]) { NSLog(@"Ok was selected."); } else if([title isEqualToString:@"Safari"]) { NSLog(@"open Safari was selected."); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]]; }
}
我使用的是prefs：root = General，但是我从下面的链接中读取…
iOS启动设置 – >限制URLscheme
…这是不可能在ios5.1。 事实上，它不能在模拟器中工作。 我能做什么？？ 谢谢您的帮助
试试这个（适用于iOS 5及更高版本）：
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Assistant "]];
“设置”应用中当前已知的url列表：
prefs:root=General&path=About prefs:root=General&path=ACCESSIBILITY prefs:root=AIRPLANE_MODE prefs:root=General&path=AUTOLOCK prefs:root=General&path=USAGE/CELLULAR_USAGE prefs:root=Brightness prefs:root=General&path=Bluetooth prefs:root=General&path=DATE_AND_TIME prefs:root=FACETIME prefs:root=General prefs:root=General&path=Keyboard prefs:root=CASTLE prefs:root=CASTLE&path=STORAGE_AND_BACKUP prefs:root=General&path=INTERNATIONAL prefs:root=LOCATION_SERVICES prefs:root=ACCOUNT_SETTINGS prefs:root=MUSIC prefs:root=MUSIC&path=EQ prefs:root=MUSIC&path=VolumeLimit prefs:root=General&path=Network prefs:root=NIKE_PLUS_IPOD prefs:root=NOTES prefs:root=NOTIFICATIONS_ID prefs:root=Phone prefs:root=Photos prefs:root=General&path=ManagedConfigurationList prefs:root=General&path=Reset prefs:root=Sounds&path=Ringtone prefs:root=Safari prefs:root=General&path=Assistant prefs:root=Sounds prefs:root=General&path=SOFTWARE_UPDATE_LINK prefs:root=STORE prefs:root=TWITTER prefs:root=General&path=USAGE prefs:root=VIDEO prefs:root=General&path=Network/VPN prefs:root=Wallpaper prefs:root=WIFI prefs:root=INTERNET_TETHERING
