The custom interior view point of attack has to deal with external events compatible, you can directly set the click event on the outside, the code can go to the warehouse https://github.com/wangsen927/MoveImageView , also can refer to the following code:
/**
* 如果view随手指拖动时，同时需要点击事件，直接在外部设置即可，内部已解决冲突
*
