Question

我正在使用UITabBar-Application。

我想用

更改所选的项目颜色

[[UITabBar appearance] setTintColor:[UIColor redColor]]

这有效，直到我想用

设置TabBar的背景颜色

[[UITabBar appearance] setBarTintColor:[UIColor blueColor]]

然后条形图为蓝色，但突出显示的项目为灰色。

[[UITabBar appearance] setBackgroundColor:[UIColor blueColor]]

无效。任何的想法？非常感谢你！

Answer 1

试用此代码

//Set greenColor for normal State
[UITabBarItem.appearance setTitleTextAttributes:@{
        UITextAttributeTextColor : [UIColor greenColor] } forState:UIControlStateNormal];
//Set purpleColor for normal State  


[UITabBarItem.appearance setTitleTextAttributes:@{
        UITextAttributeTextColor : [UIColor purpleColor] }     forState:UIControlStateSelected];

希望这有帮助。

Answer 2

您发布的代码似乎正在运行。你也可以用图像来做。试试这个：

[tabBarItem1 setImage:[[UIImage imageNamed:@"home.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
[tabBarItem1 setSelectedImage:[[UIImage imageNamed:@"home_selected.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

// Change the tab bar background
UIImage* tabBarBackground = [UIImage imageNamed:@"tabbar.png"];
[[UITabBar appearance] setBackgroundImage:tabBarBackground];
[[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:@"tabbar_selected.png"]];

UITabBar选择项目色调颜色
