Question

我有一个tabBarController和我设置的图标，但我无法选择未选择的图标成功。它接缝我只选择一个1图标和一个选定的颜色即可。

如何拍摄颜色或为未选择的状态设置单独的图标？我没有成功设置图标和所选图标。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Set the status bar to light style
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

    UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];

    UITabBarController *tabBarController = (UITabBarController*)[mainStoryboard instantiateViewControllerWithIdentifier: @"TabBar"];
    UITabBar *tabBar = tabBarController.tabBar;

    NSLog(@"%@", tabBar.items);

    UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
    //UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
    //UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];

    tabBarItem1.image = [UIImage imageNamed:@"IconTabBarFolder"];
    tabBarItem1.selectedImage = [UIImage imageNamed:@"IconTabBarFolder:Highlighted"];

    [[UITabBarItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Medium" size:10.0f], NSForegroundColorAttributeName : [UIColor colorWithRed:.5 green:.5 blue:.5 alpha:1] } forState:UIControlStateNormal];

    return YES;
}

您可以使用以下代码为UITabbarItem添加图片：

 [tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"stores222.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"home-icon-inactive.png"]];

iOS7更新：请使用此代码：

    UIImage *aImage = [UIImage imageNamed:@"a"]; 
    aImage = [aImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    UIImage *inaImage = [UIImage imageNamed:@"ina"];
    inaImage = [inaImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    self.aController.tabBarItem = [[UITabBarItem alloc]initWithTitle:@"title" image:inaImage selectedImage:aImage];

如何在标签栏中为单个项目选择2个图标？
