custom image for tabbar item

Question

изменение пользовательского изображения для UITabBar item Я использовал этот код, но он не работает.

UIImage *selectedImage0 = [UIImage imageNamed:@"f.png"]; 
UIImage *unselectedImage0 = [UIImage imageNamed:@"f.png"]; 

UIImage *selectedImage1 = [UIImage imageNamed:@"g.png"]; 
UIImage *unselectedImage1 = [UIImage imageNamed:@"g.png"]; 

UIImage *selectedImage2 = [UIImage imageNamed:@"i.png"]; 
UIImage *unselectedImage2 = [UIImage imageNamed:@"i.png"]; 

UIImage *selectedImage3 = [UIImage imageNamed:@"s.png"]; 
UIImage *unselectedImage3 = [UIImage imageNamed:@"s.png"]; 

UIImage *selectedImage4 = [UIImage imageNamed:@"t.png"]; 
UIImage *unselectedImage4 = [UIImage imageNamed:@"t.png"]; 


UITabBar *tabBar = self.tabBarController.tabBar; 
UITabBarItem *item0 = [tabBar.items objectAtIndex:0]; 
UITabBarItem *item1 = [tabBar.items objectAtIndex:1]; 
UITabBarItem *item2 = [tabBar.items objectAtIndex:2]; 
UITabBarItem *item3 = [tabBar.items objectAtIndex:3]; 
UITabBarItem *item4 = [tabBar.items objectAtIndex:4]; 

[item0 setFinishedSelectedImage:selectedImage0 withFinishedUnselectedImage:unselectedImage0]; 
[item1 setFinishedSelectedImage:selectedImage1 withFinishedUnselectedImage:unselectedImage1]; 
[item2 setFinishedSelectedImage:selectedImage2 withFinishedUnselectedImage:unselectedImage2]; 
[item3 setFinishedSelectedImage:selectedImage3 withFinishedUnselectedImage:unselectedImage3]; 
[item4 setFinishedSelectedImage:selectedImage4 withFinishedUnselectedImage:unselectedImage4]; 

Answer 1

Вы должны использовать - (UIImage *)imageWithRenderingMode:(UIImageRenderingMode)renderingMode NS_AVAILABLE_IOS(7_0); метод, как показано ниже

item0.image = [unselectedImage1 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; 
item0.selectedImage = [selectedImage1 imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; 

Answer 2

Вы установили два изображения для каждого TabItem простое изображение и изображение парят.

item0.image = [[UIImage imageNamed:@"f.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; // set simple image 

item0.selectedImage = [[UIImage imageNamed:@"f.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]; // set hover image
