4.代理属性重名

Auto property synthesis will not synthesize property 'delegate'; it will be implemented by its superclass, use @dynamic to acknowledge intention
Property type 'id' is incompatible with type 'id _Nullable' inherited from 'UITabBar'

原因:和原生提供的delegate属性重名
解决:让代理继承UITabBarDelegate,并修改属性名

@protocol XXTabBarDelegete < UITabBarDelegate >
@end

...
@property (weak, nonatomic)id < XXTabBarDelegete >myDelegate;
