UITabBar not showing selected item images in ios 7

Question

The icons show fine in ios 6 but not in ios 7. I\'m setting the selected state in the viewController viewDidLoad method. When the user selects a tab bar item the image disap

Answer 1

None of the answers worked for me - I am using MonoTouch but if you set the TintColor property of the UITabBar itself that will highlight the selected image with that color. In obj c it may be setTintColor function.

Answer 2

if you are working with storyboards you have to put the identifier : "custom" in Navigation Controller.

then :

- (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;
}

This works for me.

Set bar item image's render mode to original can solve this problem. This can be done by using images in the .xcassets, so you don't have to write lots of codes.

First step, drap&drop your bar item images to Assets.xcassets.

Second step, choose the bar item image, and change [Render As] to [Original Image]

ps: I usually set the TabBarController's tab bar items all by story board to avoid writing lots of code.

Based on the answer from 132206, I made this method for AppDelegate, called from application:didFinishLaunchingWithOptions: with:

[self configureSelectedImages];

It obviously requires a strict naming convention for your tab images, but can also be re-used without editing. To state the obvious - name your selected tab bar images TabbarXXXSelected, where XXX equals the title of the tab bar item.

- (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]];
    }
}

Answer 5

After spending a couple of hours trying to make my custom tabbar to work for both iOS 6 & 7, that's what worked for me...

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];
UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];

tabBarItem1.title = @"Home";
tabBarItem2.title = @"Map";
tabBarItem3.title = @"Weather";
tabBarItem4.title = @"Info";

if ([[[UIDevice currentDevice] systemVersion] floatValue] < 7) {
    [tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"cyexplore_home_white.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"cyexplore_home_black.png"]];
    [tabBarItem2 setFinishedSelectedImage:[UIImage imageNamed:@"cyexplore_cloud_white.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"cyexplore_cloud_black.png"]];
    [tabBarItem3 setFinishedSelectedImage:[UIImage imageNamed:@"cyexplore_map_white.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"cyexplore_map_black.png"]];
    [tabBarItem4 setFinishedSelectedImage:[UIImage imageNamed:@"cyexplore_info_white.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"cyexplore_info_black.png"]];
} else {
    tabBarItem1.selectedImage = [[UIImage imageNamed:@"cyexplore_home_white"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
    tabBarItem1.image = [[UIImage imageNamed:@"cyexplore_home_black"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

    tabBarItem2.selectedImage = [[UIImage imageNamed:@"cyexplore_cloud_white"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
    tabBarItem2.image = [[UIImage imageNamed:@"cyexplore_cloud_black"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

    tabBarItem3.selectedImage = [[UIImage imageNamed:@"cyexplore_map_white"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
    tabBarItem3.image = [[UIImage imageNamed:@"cyexplore_map_black"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];

    tabBarItem4.selectedImage = [[UIImage imageNamed:@"cyexplore_info_white"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
    tabBarItem4.image = [[UIImage imageNamed:@"cyexplore_info_black"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
}

UIImage* tabBarBackground = [UIImage imageNamed:@"tabbar.png"];
[[UITabBar appearance] setBackgroundImage:tabBarBackground];
[[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:@"tabbar_selected.png"]];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor blackColor], UITextAttributeTextColor, nil] forState:UIControlStateNormal];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor, nil] forState:UIControlStateSelected];

Add these lines of codes in

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
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];
UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];

tabBarItem1.selectedImage = [[UIImage imageNamed:@"selectimg"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem1.image = [[UIImage imageNamed:@"deselectimg"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem1.title = @"xxxx";

tabBarItem2.selectedImage = [[UIImage imageNamed:@"selectimg"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem2.image = [[UIImage imageNamed:@"deselectimg"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem2.title = @"xxxx";

tabBarItem3.selectedImage = [[UIImage imageNamed:@"selectimg"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem3.image = [[UIImage imageNamed:@"deselectimg"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem3.title = @"xxxx";

tabBarItem4.selectedImage = [[UIImage imageNamed:@"selectimg"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem4.image = [[UIImage imageNamed:@"deselectimg"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
tabBarItem4.title = @"xxxx";

return YES;
}

this works for me... and hope for the best...
