仿AppStore动画
TodayAnimation is a push/pop transition animation which is simillar to APPStore's effect! It is a category class and easy to be used!
TodayAnimation是类似于APPStore效果的push/pop转场动画！它是一个类别类，易于使用！
1. Drop files in a floder called CustomAnimation into your project。
1. 将“CustomAnimation”文件夹拖拽到你的项目。
2. set '#import "UIViewController+TodayAnimation.h"' on your wanted controller and use the category methon instead of the normal push/pop function and it will work!
2. 在你想要的控制器里导入“UIViewController+TodayAnimation.h”，使用这个类别里的push/pop方法代替系统的，控制器的push跳转就是仿APPStore效果
3. Enjoy it！！！！！！
