IOS8 - does not display custom images in the tab

I have a pre-existing app (pre iOS8) that uses a UITabbar with a custom image. Tabba is visible in iOS7 simulator and device, but not visible in iOS8. What is causing this problem? I use image

and selectedImage

properties UITabBarItem

with UIImageRenderingModeAlwaysOriginal

images. Is it an issue with the Xcode 6 or iOS (iPhone) simulator, or are we unable to use custom images (only grayscale images are allowed !?) on the tab anymore? link for image property tabbaritem

Problem with my approach when initializing tab items (in method when login is completed on the login screen itself). I have a login validation login at the login screen viewDidLoad and segueing to the main screen if the user is logged in. But in the viewWillAppear of the login, I return tabbarItems.

In the iOS 8 pre-login window, the screen is not showing and I have an initialized tab on my home screen. But in iOS 8, it displays the login screen (for a while) even if I go to the main screen from viewDidLoad.



To solve the problem, I moved the initialization code for the tab items to the home screen. enter image description here

Let's say you have an array of images in your project:

   NSArray *icons_low = [[NSArray alloc]init];
   icons_low =  [NSArray arrayWithObjects:@"first_tab_ic.png",  @"second_tab_ic.png", @"third_tab_ic.png", @"4th_tab_ic.png", nil];
   for(int i=0;i<icons_low.count;i++) {
          UITabBarItem *item = [self.tabBarController.tabBar.items objectAtIndex:i];
          NSString *img_name = [NSString stringWithFormat:@"%@", [icons_low objectAtIndex:i] ];
 /* deprecated -> comment such lines  
  [item setFinishedSelectedImage:[UIImage imageNamed:img_name] withFinishedUnselectedImage:
         [UIImage imageNamed:img_name]]; */
         item.image = [[UIImage imageNamed:img_name]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal ];
         item.selectedImage = [[UIImage imageNamed:img_name]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    }


But I also suspect that your tablet (check the XIB) has set something related to setBarStyle.

You can use the following code:

UITabBarItem *maps = [[UITabBarItem alloc] initWithTitle:nil image:[[UIImage imageNamed:@"map_icon"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] tag:3];
[navMaps setTabBarItem:maps];
