图标在 ios 6 中显示正常，但在 ios 7 中显示不正常。我在 viewController viewDidLoad 方法中设置选定状态。当用户选择标签栏项目时，图像会消失。这是我的代码：

UITabBar *tabBar = self.tabBarController.tabBar;
if ([UITabBar instancesRespondToSelector:@selector(setSelectedImageTintColor:)]) {
    [self.tabBarController.tabBar setSelectedImageTintColor:[UIColor whiteColor]];
}
UITabBarItem *item0 = [tabBar.items objectAtIndex:0];
UITabBarItem *item1 = [tabBar.items objectAtIndex:1];
UITabBarItem *item2 = [tabBar.items objectAtIndex:2];
UITabBarItem *item3 = [tabBar.items objectAtIndex:3];
[item0 setTitle:@"Home"];
[item1 setTitle:@"Calendar"];
[item2 setTitle:@"News"];
[item3 setTitle:@"My Events"];
[item0 setFinishedSelectedImage:[UIImage imageNamed:@"homeIconSelected.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"home2.png"]];
[item1 setFinishedSelectedImage:[UIImage imageNamed:@"Calendar"] withFinishedUnselectedImage:[UIImage imageNamed:@"CalendarIconSelected"]];
[item2 setFinishedSelectedImage:[UIImage imageNamed:@"NewsIconSelected"] withFinishedUnselectedImage:[UIImage imageNamed:@"News"]];
[item3 setFinishedSelectedImage:[UIImage imageNamed:@"EventsIconSelected"] withFinishedUnselectedImage:[UIImage imageNamed:@"Events"]];
[item1 imageInsets];
[item2 imageInsets];
[item3 imageInsets];

您需要使用 tabBarIteminitWithTitle:image:selectedImage

[[UITabBarItem alloc] initWithTitle:@"title" image:image selectedImage:imageSel];

结合改变 UIImage 渲染模式：

imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal

或（要应用父视图模板色调遮罩，此选项是选项卡栏项目的默认选项，除非您选择退出上述渲染模式）

imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate

这是一个标签栏项目的代码示例：-

UIImage *musicImage = [UIImage imageNamed:@"music.png"];
UIImage *musicImageSel = [UIImage imageNamed:@"musicSel.png"];

musicImage = [musicImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
musicImageSel = [musicImageSel imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

self.musicViewController.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"Music" image:musicImage selectedImage:musicImageSel];

希望这可以帮助

将 bar item image 的渲染模式设置为 original 可以解决这个问题。这可以通过使用 .xcassets 中的图像来完成，因此您不必编写大量代码。

第一步，将您的条形项目图像拖放到 Assets.xcassets。

第二步，选择bar item图片，将【Render As】改为【Original Image】

ps：我一般都是通过storyboard来设置TabBarController的标签栏项，避免写很多代码。

如果您正在使用情节提要，则必须将标识符：“自定义”放在导航控制器中。

然后 ：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Assign tab bar item with titles
    UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
    UITabBar *tabBar = tabBarController.tabBar;
    UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
    UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
    UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];

    (void)[tabBarItem1 initWithTitle:nil image:[UIImage imageNamed:@"home.png"] selectedImage:[UIImage imageNamed:@"home_selected.png"]];
    (void)[tabBarItem2 initWithTitle:nil image:[UIImage imageNamed:@"home.png"] selectedImage:[UIImage imageNamed:@"home_selected.png"]];
    (void)[tabBarItem3 initWithTitle:nil image:[UIImage imageNamed:@"home.png"] selectedImage:[UIImage imageNamed:@"home_selected.png"]];

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



    return YES;
}

这对我有用。

没有一个答案对我有用——我使用的是 MonoTouch，但如果你设置TintColor了自身的属性UITabBar，它将用该颜色突出显示所选图像。在 obj c 中它可能是setTintColor函数。

您应该写入函数：

UIImage* tab_image = [UIImage imageNamed:@"tab_image.png"];
UIImage* tab_image_selected = [UIImage imageNamed:@"tab_image_selected.png"];

tab_image = [tab_image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
tab_image_selected = [tab_image_selected imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

self.tabBarItem.image = tab_image;
self.tabBarItem.selectedImage = tab_image_selected;

我对 Xcode 6.0.1 (6A317) 有同样的问题，似乎是 Interface builder 的一个错误。但是，我设法通过selected image在界面构建器中留空然后在viewDidLoad我插入的每个视图控制器中解决它：

[self.navigationController.tabBarItem setSelectedImage:[UIImage imageNamed:@"imagename-selected"]];

它现在运行良好，显示我的selectedImage和带有全局色调掩码。

根据 132206 的回答，我为 AppDelegate 制作了这个方法，调用方法application:didFinishLaunchingWithOptions:如下：

[self configureSelectedImages];

它显然需要对标签图像进行严格的命名约定，但也可以在不编辑的情况下重复使用。显而易见 - 将您选择的标签栏图像命名为 TabbarXXXSelected，其中 XXX 等于标签栏项目的标题。

- (void)configureSelectedImages
{
    UITabBarController *tabBarController = (UITabBarController *)self.window.rootViewController;
    UITabBar *tabBar = tabBarController.tabBar;

    for (UITabBarItem *tabBarItem in [tabBar items]) {
        NSString *selectedImage = [NSString stringWithFormat:@"Tabbar%@Selected", [tabBarItem title]];
        (void)[tabBarItem initWithTitle:[tabBarItem title] image:[tabBarItem image] selectedImage:[UIImage imageNamed:selectedImage]];
    }

在您的第一个视图控制器的 .h 文件中，我添加了以下内容：@property (weak, nonatomic) IBOutlet UITabBarItem *mapViewTabBarItem; @property (weak, nonatomic) IBOutlet UITabBarItem *profileViewTabBarItem; @property (weak, nonatomic) IBOutlet UITabBarItem *notificationViewTabBarItem;

（请注意，mapViewTabBarItem 是通过 ctrl 将实际的选项卡栏项拖动到 .h 文件顶部的属性声明列表中来链接的）

接下来，在 viewDidLoad 的同一个视图控制器的 .m 文件中，添加以下内容：

self.tabBarItem = [self.tabBarController.tabBar.items objectAtIndex:0];
_mapViewTabBarItem.selectedImage = [[UIImage imageNamed:@"@2x-map-icon-selected.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
self.tabBarItem.image = [[UIImage imageNamed:@"@2x-map-icon.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

我有一个类似的问题。我在情节提要中创建了标签栏，并通过界面构建​​器菜单添加了所有图像，代码中没有。

我的修复实际上很简单：在 IB 的属性检查器窗口下，“选定图像”的选项卡栏项目字段应该是空白的，“图像”的栏项目字段应该填充您想要的图像。

我正在运行 Xcode 6.0.1 并使用 iOS 8.0.2 设备进行测试。

我遇到过同样的问题。但是使用 StoryBoards 使我无法更改代码中的任何内容。在情节提要中将图像留空为我消除了这个障碍。然而，将 initWithTitle 放在选项卡视图控制器的 viewWillAppear 方法中给了我奇怪的行为。首先获取所选图像需要额外单击，并且图像不会显示在非初始选项卡中。

对我来说，解决这个问题是将以下代码添加到 DidFinishLoadingWithOptions 中的 AppDelegate（类似于 132206 和 Amitabha）：

NSArray * vcs = [(UITabBarController*)self.window.rootViewController viewControllers];
UIViewController *tab0 = [[(UINavigationController*)[vcs objectAtIndex:0] viewControllers] objectAtIndex:0];
tab0.title = NSLocalizedString(@"Time", nil);
tab0.tabBarItem =  [[UITabBarItem alloc] initWithTitle:tab0.title image:[UIImage imageNamed:@"Recents.png"] selectedImage:[UIImage imageNamed:@"RecentsSolid.png"]];
UIViewController *tab1 = [[(UINavigationController*)[vcs objectAtIndex:1] viewControllers] objectAtIndex:0];
tab1.title = NSLocalizedString(@"Expense", nil);
tab1.tabBarItem = [[UITabBarItem alloc] initWithTitle:tab1.title image:[UIImage imageNamed:@"Euro.png"] selectedImage:[UIImage imageNamed:@"EuroSolid.png"]];

它是 UITabBar 项目的简单而干净的类别解决方案。

只需创建类别并使用运行时属性并从如下类别中引用它。 为选定的 TabBarItem 添加运行时属性 从类别中引用它并进行更改

#import "UITabBarItem+CustomTabBar.h"

@implementation UITabBarItem (CustomTabBar)

-(void)setValue:(id)value forKey:(NSString *)key {
    if([key isEqualToString:@"tabtitle"]){
        if([value isEqualToString:@"contacts"]) {
            [self setSelectedImage:[[UIImage imageNamed:@"contacts-selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
        } else if([value isEqualToString:@"chat"]) {
            [self setSelectedImage:[[UIImage imageNamed:@"chat-selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
        } else if([value isEqualToString:@"groupchat"]) {
            [self setSelectedImage:[[UIImage imageNamed:@"groupchat-selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
        } else if([value isEqualToString:@"settings"]) {
            [self setSelectedImage:[[UIImage imageNamed:@"settings-selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
        }
    }
    [self setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Roboto-Regular" size:12.0f], NSFontAttributeName, [UIColor grayColor], NSForegroundColorAttributeName, nil] forState:UIControlStateNormal];

老问题，但也将为 Xamarin.iOS/C# 和那些想要通过界面生成器设置图像的人添加我的解决方案。我通过 Interface Builder 设置Selected ImageandImage属性。然后在代码中我定义了一个InitTabs()这样的方法：

public void InitTabs(){
        HomeTab.SelectedImage = HomeTab.SelectedImage.ImageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
        HomeTab.Image = HomeTab.Image.ImageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
}

调用InitTabs()，ViewDidLoad现在将显示选定和未选定状态的正确图像。

这是 Swift-Guys 的 Swift 解决方案 :)

class CustomTabBar: UITabBar {

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        let btnNames = ["Title1", "Title2", "Title3", "Title4"]

        for (item, name) in zip(items!, btnNames) {
            item.image = UIImage(named: "bar\(name)Btn")?.imageWithRenderingMode(.AlwaysOriginal)
            item.selectedImage = UIImage(named: "bar\(name)SelectedBtn")?.imageWithRenderingMode(.AlwaysOriginal)
            item.title = name
            item.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState: .Normal)
            item.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.redColor()], forState: .Selected)
        }
    }

}

这里到底发生了什么：

  • 制作 btn 标题数组并考虑图像文件名以匹配它们
  • 在标签栏项目上进行 For 循环并刚刚创建 btn 标题数组
  • 从数组中设置 barButtonItem 的图像及其 selectedImage
  • 从数组中设置标题文本
  • 为状态 .Normal 和 .Selected 设置标题文本颜色

如果您不想将 .Normal 的项目标题颜色保留为灰色，.Selected 保留为蓝色，则设置文本颜色部分很重要，因为它是默认设置。当您考虑标签栏项目的自定义图像时，这通常是实际的。
