【UI-基础】改变UITabBarItem图片的颜色及文字

UIImage* tabBarBackground = [UIImage imageNamed:@"biaoqian.png"];

[[UITabBar appearance] setBackgroundImage:tabBarBackground];//设置背景，修改颜色是没有用的

[[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:@"tm.png"]];

[[UITabBar appearance] setShadowImage:[UIImage imageNamed:@"tm.png"]];//隐藏那条黑线

[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColorgrayColor], UITextAttributeTextColor,nil] forState:UIControlStateNormal];

UIColor *titleHighlightedColor = [UIColor colorWithRed:198/255.0 green:59/255.0 blue:82/255.0 alpha:1.0];

[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionarydictionaryWithObjectsAndKeys:titleHighlightedColor, UITextAttributeTextColor,nil]forState:UIControlStateHighlighted];
