Cat learning iOS (30) UI quartz2d picture Drawing text

Looking back at the blog you wrote, the cat decided to change the style later
The original intention is to see the effect of direct copy code can be used, complete annotation is also convenient to learn, but found that this is particularly difficult for beginners to learn, the source of material will not be uploaded, there is want to go to the group to find.
After the style is basically –> look at the title –> look at the directory –> see the picture –> see the code –> own try.

Of course, if there is a good for the demo cat will be the same as the original put up.
