UIAlertControl的使用对比与UIAlertView和UIActionSheet

- (void)viewDidLoad {
    [super viewDidLoad];
    //UIAlertView的使用
    [self showAlert];
    
    //UIAcyionSheet使用
//    [self showAction];
    
#pragma mark  [self showAlertController];方法不可以放在此处因为UIAlertControl继承与UIViewController
    //UIAlertControl的使用
//    [self showAlertController];
    
   }
