tab bar icon selected image

问题:

How to customize the selected image/icon on the tab bar? Is this possible?

Pls advise. Thanks

回答1:

Its possible without adding any subView.

In the class where you define the tab bar set the property of the tabBarItem to ->>

UITabBarItem *tabBarItem1 = [[self.tabBar.tabBar items] objectAtIndex:0]; [tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"campaigns_hover.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"campaigns.png"]]; 

Its a property of tabBarItem and u can change the default blue image to a custom image. campaigns_hover.png is the selected custom image AND campaigns.png is the custom image when not selected...

Enjoy the secret.. :)

In iOS 6 I have change the selected Tabbaritem image like -

In the Tabbar controller delegate method

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController  {     if([tabBarController selectedIndex] == 0)     {         [viewController.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"selected.png"]withFinishedUnselectedImage:[UIImage imageNamed:@"unselect.png"]];     }     } 

through this you can change your image.

Or you can use directly in your view controllers init(or ViewWillAppear) method, like

[viewController.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"selected.png"]withFinishedUnselectedImage:[UIImage imageNamed:@"unselect.png"]];

You can change the image, but the selected image always has the same blue overlay applied to the image. The only way I can see getting around this might be to subclass UITabBarItem.

回答4:

Yes. Just read the Apple documentation

You can do by IB or code
