检查UIView是否被触动？

Question

嘿，我希望能够检查用户是否触及我的UIView，这样我就可以解雇我的选择器，我怎么能够实际执行它？谢谢！

尝试在包含您的UIView的UIViewController子类的viewDidLoad加入UITapGestureRecognizer您UIView类。这将是这个样子：

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped:)]; 
    tap.numberOfTapsRequired = 1; 
    [self.aView addGestureRecognizer:tap]; 
    [tap release]; 
} 

然后实现了其基于上面的代码水龙头的处理程序，应该是这样的：

-(void)viewTapped:(UITapGestureRecognizer *)recognizer { 
    //Add in your picker dismissal code here 
} 

希望这有助于
