iOS tabbar setSelectedImageTintColor 这个方法不可以改变tabbar颜色了 用下面方法代替把

UITabBarController*tabBarController =(UITabBarController*) self.window.rootViewController;

UITabBar*tabBar = tabBarController.tabBar;

for(UITabBarItem*item in tabBar.items)

{
UIImage*image = item.image;

UIImage*correctImage =[image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
       

 item.image = correctImage;
}
[[UITabBar appearance] setTintColor:[UIColor whiteColor]];

[[UITabBar appearance] setSelectedImageTintColor:[UIColor colorWithRed:44.0/255.0 green:176.0/255.0 blue:28.0/255.0 alpha:1.0]];

[[UITabBar appearance] setBarTintColor:[UIColor colorWithRed:51.0/255.0 green:51.0/255.0 blue:51.0/255.0 alpha:1.0]];
