IOS Custom button (code implementation) + nine Gongge

In some download applications the entire page is a button, there are a lot of many, but careful observation is not difficult to find that they are very regular. Just like the following??

Very regularly arranged on the screen, then this requires how we can do it.

As the title, we need to understand two knowledge points, respectively, are custom buttons and nine Gongge, nine Gongge is an algorithm. Here I give you a list of methods, not too much explanation, hope will be helpful to everyone.

The code is as follows:
