Uiscrollview proxy (delegate)

• In many cases, we want to perform some specific operations when uiscrollview is rolling or rolling to a certain position or stopping the rolling • to complete the above functions, the precondition is that you can monitor the entire Rolling Process of uiscrollview • when a series of rolling operations occur in uiscrollview, its proxy (delegate) object is automatically notified, send a message to its proxy to let the proxy know its rolling status • to listen to the uiscrollview rolling process, you must first set a proxy object for uiscrollview, then, the scrolling process of uiscrollview is known through the proxy.

To become the delegate of uiscrollview, it is conditional. You must implement the corresponding method to listen to the rolling process of uiscrollview.
