如何给uiimageview添加点击事件

给的UIImageView增加点击事件解决思路1：网友提示在该“button”上增加一个真正的透明button，这样就可以顺利执行点击事件了；但是本人尝试发现，如果我调整了button的透明度后，点击是没有效果的！可能是我操作错误，待再次验证。解决思路2：为的UIImageView增加手势[ImageView的addGestureRecognizer：我们自己的手势识别]如何创建一个手势？看看UITapGestureRecognizer的用法吧//单指单击UITapGestureRecognizer*singleFingerOne=[[UITapGestureRecognizer页头]initWithTarget：自操作：@selector（handleSingleFingerEvent:)]singleFingerOne.numberOfTouchesRequired=1;//手指数singleFingerOne.numberOfTapsRequired=1;//抽头次数singleFingerOne委托=自我;//单指双击UITapGestureRecognizer*singleFingerTwo=[[UITapGestureRecognizer页头]initWithTarget：自操作：@selector（handleSingleFingerEvent:)];singleFingerTwo.numberOfTouchesRequired=1;singleFingerTwo.numberOfTapsRequired=2;。singleFingerTwo委托=自我;//双指单击UITapGestureRecognizer*doubleFingerOne=[[UITapGestureRecognizer页头]initWithTarget：自操作：@selector（handleDoubleFingerEvent:)];doubleFingerOne.numberOfTouchesRequired=2;doubleFingerOne.numberOfTapsRequired=1;。doubleFingerOne委托=自我;UITapGestureRecognizer*doubleFingerTwo=[[UITapGestureRecognizer页头]initWithTarget：自操作：@selector（handleDoubleFingerEvent:)];doubleFingerTwo.numberOfTouchesRequired=2;doubleFingerTwo.numberOfTapsRequired=2;。doubleFingerTwo委托=自我;//如果不加下面的话，当单指双击时，会先调用单指单击中的处理，再调用单指双击中的处理[singleFingerOnerequireGestureRecognizerToFail：singleFingerTwo]//同理双指亦是如此[doubleFingerOnerequireGestureRecognizerToFail：doubleFingerTwo][self.viewaddGestureRecognizer：singleFingerOne][self.viewaddGestureRecognizer：singleFingerTwo][self.viewaddGestureRecognizer：doubleFingerOne][self.viewaddGestureRecognizer：doubleFingerTwo][singleFingerOne发布][singleFingerTwo发布][doubleFingerOne发布][doubleFingerTwo发布]处理事件的方法，代码：//处理单指事件-（无效）handleSingleFingerEvent：（UITapGestureRecognizer*）发件人{如果（sender.numberOfTapsRequired==1）{//单指单击的NSLog（@“单指单击”）;}否则如果（sender.numberOfTapsRequired==2）{//单指双击的NSLog（@“单指双击”）;}}//处理双指事件-（无效）handleDoubleFingerEvent：（UITapGestureRecognizer*）发件人{如果（sender.numberOfTapsRequired==1）{//双指单击的NSLog（@“双指单击”）;}否则如果（sender.numberOfTapsRequired==2）{//双指双击的NSLog（@“双指双击”）;}}
