推荐答案

可以使用手势识别器完成拖放控件。 Here is sample from Ray Wenderlich. The principles and some code should be reuseable for your needs.



Tip: rethink and simplify your code, I would call it \"Spaghetti-code\" ;-)

Drag and drop of controls can be done with gesture recognizers. Here is sample from Ray Wenderlich. The principles and some code should be reuseable for your needs.
