Dark dishes One of the changes UITableViewCell left slide the style and customization of the Delete button

In the daily development we may encounter the need to customize the UITableViewCell left slide Delete button style, there are many custom third-party online, but all too heavyweight, should be for us maybe we need very small, and do not want to import a third party, and then set a variety of a lot of properties, Too much trouble, then how to modify the system comes with it?

Maybe you say can't modify, million is not absolute, we have artifact reveal, as an iOS program ape, if you even reveal do not know or will not use you are too low, OK, we started our dark dishes.

First, let's look at the hierarchical relationship of the UITableViewCell left slide button under Reveal,

Let's see, this is a hierarchical relationship in the left-slip state of the cell.

1,cell There are two Subview, one is Uitableviewcelldeleteconfirmationview, this class we in Xcode can not find out, so we do not find

The Delete button is added to the

Uitableviewcelldeleteconfirmationview This class corresponds to the view above, so you add the time to add to him, the layout size is set according to his frame, you can also add constraints. Interested students try
