ios-IOS多個UIView添加點擊

IOS多個UIView添加點擊

剛剛接觸IOS開發，遇到以下問題想不通，希望高手給予指導。我給sendView、 payVIew、receiverView、 commentView設置點擊事件，為什麼
UITapGestureRecognizer * singleRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(viewClick:)];
singleRecognizer.numberOfTapsRequired = 1;
[self.sendView addGestureRecognizer:singleRecognizer];
[self.payVIew addGestureRecognizer:singleRecognizer];
[self.receiverView addGestureRecognizer:singleRecognizer];
[self.commentView addGestureRecognizer:singleRecognizer];
只有commentView能夠響應點擊事件，其他的三個UIView都無法響應點擊事件，但是我要是改成

UITapGestureRecognizer * singleRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(viewClick:)];
singleRecognizer.numberOfTapsRequired = 1;
[self.sendView addGestureRecognizer:singleRecognizer];

UITapGestureRecognizer * singleRecognizer1 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(viewClick:)];
singleRecognizer1.numberOfTapsRequired = 1;
[self.payVIew addGestureRecognizer:singleRecognizer1];

UITapGestureRecognizer * singleRecognizer2 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(viewClick:)];
singleRecognizer2.numberOfTapsRequired = 1;
[self.receiverView addGestureRecognizer:singleRecognizer2];

UITapGestureRecognizer * singleRecognizer3 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(viewClick:)];
singleRecognizer3.numberOfTapsRequired = 1;
[self.commentView addGestureRecognizer:singleRecognizer3];
    就可以了呢？希望好心人能夠給我這個新手指點迷津

最佳回答：

第一種用法相當於創建了一個點擊手勢 給四個View賦值 它只可以賦值給一個對象 先給sendView賦值 一直執行代碼 最後賦值給了commentView，也就是前三個並沒有賦值上了，第二種寫法就是創建了4個點擊手勢分別給四個View賦值，就咩有問題了
