Change the tint color of the UIWindowof the application. You can either use the [[UIApplication sharedApplication] keyWindow]but better is to use [[UIApplication sharedApplication] delegate].window.
更改UIWindow应用程序的色调颜色。您可以使用 ，[[UIApplication sharedApplication] keyWindow]但更好的是使用[[UIApplication sharedApplication] delegate].window.

UIAppearanceis the answer! It sets property to all the objects of that class (and subclasses).
UIAppearance就是答案！它将属性设置为该类（和子类）的所有对象。
[[UIView appearance] setTintColor:(UIColor *)]
You can change the backgroudColorof all the buttons too
您也可以更改backgroudColor所有按钮的
[[UIButton appearance] setBackgroundColor:(UIColor *)]
