@interface KKTabBar : UITabBar NS_CLASS_AVAILABLE_IOS(2_0) @interface UITabBar : UIView UITabBar 繼承自 UIView
所以可以在 UITabBar 上添加view啦。 - (instancetype)init {self = [super init];if (self) {UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"menu_bottom"]];imgView.size = CGSizeMake([UIScreen mainScreen].bounds.size.width, 49);[self addSubview:imgView];UIView *view = [[UIView alloc] init];view.size = CGSizeMake([UIScreen mainScreen].bounds.size.width/4, 2);view.x = 0;view.y = 0;view.backgroundColor = [UIColor whiteColor];[self addSubview:view];self.barTopView = view;}return self; }
