Ios Utiabar外观不工作

当使用以下代码行选择UITabBarItem时，我正在尝试更改其色调颜色：

[[UITabBar appearance]setTintColor:[UIColor colorWithRed:89 green:216 blue:239 alpha:1]];

但是，当我选择选项卡栏时，着色颜色变为白色

有人知道为什么吗

谢谢大家!

将selectedImageTintColor属性设置为您的颜色。

在uicolor:RGB中，您需要设置255的值

[UIColor colorWithRed:89/255.0f green:216/255.0f blue:239/255.0f alpha:1]

在应用程序代理的didFinishLaunching方法中尝试以下操作：

[[UITabBar appearance] setSelectedImageTintColor:[UIColor colorWithRed:89/255.0f green:216/255.0f blue:239/255.0f alpha:1]];

在iOS 7中使用：

[[UITabBar appearance] setTintColor:[UIColor colorWithRed:89/255.0f green:216/255.0f blue:239/255.0f alpha:1]];
