我有以下功能会弹出一个 UIAlert，允许用户更新他们的触觉反馈设置：

- (void)requestHapticSetting{

    alertWindow.rootViewController = [[UIViewController alloc] init];
    alertWindow.windowLevel = UIWindowLevelAlert + 1;
    [alertWindow makeKeyAndVisible];

    if(isHapticOn){

    }
    else {

                                                     }];

    UIAlertAction* offAction = [UIAlertAction actionWithTitle:@"TURN OFF" style:UIAlertActionStyleDefault
                                                      handler:^(UIAlertAction * action) {
