Reuse of IOS drop-down menus and ios drop-down menus

Reuse of IOS drop-down menus and ios drop-down menus

Since I used the drop-down menu before, I have spent some time looking back and finishing it, gradually improving the drop-down menu and providing some basic functions, in this way, you can reuse it if necessary in the future and provide it to users who need it for reference. The drop-down menu is also divided into data source and proxy methods. The following methods are provided:
