一個UITapGestureRecognizer使鍵盤皮，當我觸摸到一個UIButton

我在頭文件中聲明裏面不起作用此：一個UITapGestureRecognizer使鍵盤皮，當我觸摸到一個UIButton

UITapGestureRecognizer* tap;

而且在viewDidLoad：

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 

    tap = [[UITapGestureRecognizer alloc] initWithTarget:self 
                action:@selector(hideKeyboard)]; 
    tap.enabled = NO; 
    [self.view addGestureRecognizer:tap]; 
}

我已經添加UITextFieldDelegate，並添加這樣的：

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField 
{ 
    tap.enabled = YES; 

    return YES; 
}

如果我碰到的任何地方Ø在鍵盤上，它會消失，但如果我在UIButton中觸摸它並不會消失。

你知道爲什麼嗎？

看看[這裏]（http://stackoverflow.com/questions/3344341/uibutton - 內 - 一 - 視圖 - 即-具有-A-uitapgesturerecognizer） – luiso1979

UIButton攔截並處理觸摸（不傳播它）。一種選擇是設置您的視圖控制器作爲手勢識別代表和實現方法：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch

但在你的情況下，我認爲這將是足以解聘的方法觸發該鍵盤在按下按鈕時。

UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)]; 
    tapGestureRecognizer.delegate = self; 
    tapGestureRecognizer.numberOfTapsRequired = 1; 
    [self.view addGestureRecognizer:tapGestureRecognizer]; 


- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { 


    if (touch.view == self.button) {//change it to your condition UIButton 
     return NO; 
    } 
    return YES; 
} 

-(void)dismissKeyboard 
{ 
    [self.textField resignFirstResponder]; 
}

添加一個目標 - 動作配對當用戶觸摸向下按鈕：

[button addTarget:self 
      action:@selector(dismissKeyboard) 
forControlEvents:UIControlEventTouchDown];
