我知道此问题也已在早些时候提出，但我仍然无法在互联网上搜索解决方案。

I know this question has been asked earlier as well, but still i didn't get any solution searching the solution on internet.

推荐答案

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，另一个是未选中的。

I'm assuming that you do not want to change the color using tintColor? Another option is to use two images that look exactly the same, but differ in color. One image is the selected tab, the other is unselected.

在 AppDelegate.m - （BOOL）应用程序：（UIApplication *）应用程序didFinishLaunchingWithOptions：（NSDictionary *）launchOptions 函数，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根视图控制器的人，你可以像这样抓住控制器，其余代码是相同的。

For those who don't have the tab bar controller as their root view controller, you can grab the controller like this and the rest of the code is the same.

UITabBarController * tabBarController = self.tabBarController;
