UITabBarController 重叠

UITabBarController 建议 item 的切图只包含图片，文字用程序实现，否则很重影。

-(void)removeTabBarBtn{

for(UIView*tabBarinself.tabBar.subviews){

if([tabBarisKindOfClass:NSClassFromString(@"UITabBarButton")]){

[tabBarremoveFromSuperview];

        }

    }

}

// 重影[[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(removeTabBarBtn)name:@"removeTabBarBtn"object:nil];

-(void)dealloc{[[NSNotificationCenterdefaultCenter]removeObserver:selfname:@"removeTabBarBtn"object:nil];}
