UITabBar所选项目色调

Question

我正在研究UITabBar应用程序。

我想更改选定项目颜色与

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

这工作，直到我想设置的TabBar的背景颜色与

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

那么酒吧是蓝色的，但高亮项目是灰色的。

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

没有效果。 任何想法？ 非常感谢！

Answer 1

您发布的代码似乎正在工作。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"]]; 

Answer 2

试试这个代码

//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]; 

希望这有助于。
