檢查UIView是否被觸動？

Question

嘿，我希望能夠檢查用戶是否觸及我的UIView，這樣我就可以解僱我的選擇器，我怎麼能夠實際執行它？謝謝！

嘗試在包含您的UIView的UIViewController子類的viewDidLoad加入UITapGestureRecognizer您UIView類。這將是這個樣子：

- (void)viewDidLoad { 
    [super viewDidLoad]; 

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

然後實現了其基於上面的代碼水龍頭的處理程序，應該是這樣的：

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

希望這有助於
