Question

我知道此问题也已在早些时候提出过，但我仍然无法在互联网上搜索解决方案。

我提到了以下帖子：

How can I change the text and icon colors for tabBarItems in iOS 7? 仅能使用tintColor更改所选图标颜色。

How to change the color of unselected tab bar items in iOS 7? 在此，他们编写了自己的GozTabBar类继承自UIView

我想更改UITabBar图标处于未选中状态时的默认灰色。

任何帮助都将受到高度赞赏。提前谢谢。

Answer 1

我假设您不想使用tintColor更改颜色？另一种选择是使用两个看起来完全相同但颜色不同的图像。一个图像是选定的选项卡，另一个图像是未选中的。

在AppDelegate.m - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions函数中，试试这个。

UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
UITabBar *tabBar = tabBarController.tabBar;

// repeat for every tab, but increment the index each time
UITabBarItem *firstTab = [tabBar.items objectAtIndex:0];

// also repeat for every tab
firstTab.image = [[UIImage imageNamed:@"someImage.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
firstTab.selectedImage = [[UIImage imageNamed:@"someImageSelected.png"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

编辑：对于那些没有标签栏控制器作为其根视图控制器的人，可以像这样获取控制器，其余代码是相同的。

UITabBarController *tabBarController = self.tabBarController;

Answer 2

如果您已使用Storyboard配置标签栏图像，只需在第一个视图的ViewDidLoad中调用此方法：

-(void) configTabBar
{     
    UITabBarController *tabBarController = [self tabBarController];
    UITabBar *tabBar = tabBarController.tabBar;

    for (UITabBarItem  *tab in tabBar.items) {
        tab.image = [tab.image imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal];
        tab.selectedImage = [tab.image imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal];
    }
}

[[UITabBar appearance] setTintColor:[UIColor colorWithRed:252/255.0 green:218/255.0 blue:49/255.0 alpha:1.0]];

tabBarItem1.image = [[UIImage imageNamed:@"home_icon.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    tabBarItem1.selectedImage = [UIImage imageNamed:@"home_icon_selected.png"];

[[UITabBar appearance] setBackgroundColor:[UIColor colorWithRed:15/255.0 green:85/255.0 blue:160/255.0 alpha:1.0]];
    // Change the title color of tab bar items
    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                       [UIColor whiteColor], NSForegroundColorAttributeName,
                                                       nil] forState:UIControlStateNormal];
    UIColor *titleHighlightedColor = [UIColor colorWithRed:252/255.0 green:218/255.0 blue:49/255.0 alpha:1.0];
    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                       titleHighlightedColor, NSForegroundColorAttributeName,
                                                       nil] forState:UIControlStateHighlighted]

Answer 4

将UIControlStateHighlighted更改为iOS8的UIControlStateSelected

 [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                           [UIColor whiteColor], NSForegroundColorAttributeName,
                                                           nil] forState:UIControlStateNormal];
    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                           titleHighlightedColor, NSForegroundColorAttributeName,
                                                           nil] forState:UIControlStateSelected]

要更改iOS 7中所选标签栏图标的颜色？
