How IOS sets the settings for the TableView list on the cell delete key, sticky button, unread info button

Ideas are important!

Mainly write down my implementation of the specific ideas, the effect: first, the cell to the left, when the deletion of the top button, then we can design a two-layer control on the cell, the first layer is you want to add the deletion of the top button, put these buttons on the right side of the cell and the second layer is  Put a uiview the size of the UIView is the same as the size of the cell and then add some controls to the UIView to display the data.  Question: Does the first layer of delete and top buttons not be overwritten? For this effect, the solution now is to add a pangesture gesture to the UIView. When you swipe the UIView to the left on the cell, the UIView moves to the left, and the bottom button appears. Click the button to implement the function you want to implement.

Summary: The first time to write a blog, do not know how to write will let you better understand the first to write down the idea of how we need the code can contact me
