專案中把imageView替換成UILabel，然後發現label沒有點選事件，但是可以加手勢，程式碼如下：

CGRect titleFrame = CGRectMake(0, 55, 300, 15);  

UILabel *titleLabel = [[UILabel alloc] initWithFrame:titleFrame];  

titleLabel.text [email protected]“標題”;

  //建立手勢例項，並連線方法UITapGestureRecognizer,點選手勢  

UITapGestureRecognizer *tapGesture=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(onClickUILable:)];

titleLabel.userInteractionEnabled=YES;

//設定手勢點選數,雙擊：預設不設定 就是1 為單擊事件  

tapGesture.numberOfTapsRequired=2;  

//設定手指數 單指  

tapGesture.numberOfTouchesRequired=1; 

// titleLabel新增手勢識別  

[titleLabel addGestureRecognizer:tapGesture];

//定義響應事件

-(void)onClickUILable:(UITapGestureRecognizer *)sender{

        UITapGestureRecognizer *tap = (UITapGestureRecognizer*)sender;  

        UILabel *la=(UILabel*)tap.view;  

        //相應程式碼 

}
