自定义控制器的UIAppearance

我有一个自定义视图控制器,比如MyViewController。它具有颜色属性,应使用UIAppearance机制进行更改。我做了文档告诉要做的事情 - 将属性标记为UI_APPEARANCE_SELECTOR。控制器符合UIAppearanceUIAppearanceContainer。当我试图运行应用程序时,我遇到了崩溃:

'+[MyViewController appearance]: unrecognized selector sent to class 0x10d6724f8'

为什么我的课程没有生成外观方法?是因为它是一个视图控制器而不是一个视图?如果是,那么这是否意味着自定义UIAppearance属性仅支持UIView s?

更新:发布一些代码示例:

@interface MyViewController : UIViewController <UIAppearance, UIAppearanceContainer>

@property (nonatomic) UIColor *blurTintColor UI_APPEARANCE_SELECTOR;

@end

...

// somewhere in theme setup codes which run when launching the app
MyViewController *cont = [MyViewController appearance];
cont.blurTintColor = [UIColor redColor];
