工具栏选中的项目色调颜色

Question

我正在做一个uitabbar应用程序。

我想用

改变选中的项目颜色

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

这是可行的，直到我想用

设置标签栏的背景色

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

则该栏为蓝色，但突出显示的项目是灰色的。

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

无效。任何想法?非常感谢!

Answer 1

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];

你的代码，你已经发布，似乎是工作。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"]];
