Again, a little bit of a grey area as you are overriding private methods. So,
this very well could break in future updates. Be warned. But here is an
example for your understanding-
Subclass UITabBarItem and override the private method selectedImage.
@interface GRCustomUITabBarItem : UITabBarItem
{
UIImage *customHighlightedImage;
}
@property (nonatomic, retain) UIImage *customHighlightedImage;
@end
@implementation GRCustomUITabBarItem
@synthesize customHighlightedImage;
- (void) dealloc
{
[customHighlightedImage release]; customHighlightedImage=nil;
[super dealloc];
}
-(UIImage *) selectedImage
{
return self.customHighlightedImage;
}
@end
Then in the init of each one of the viewControllers that corresponds to a tab,
you setup the tabBarItem
// Customized Tab Bar Item
GRCustomUITabBarItem *tabItem = [[GRCustomUITabBarItem alloc]
initWithTitle:@"Home" image:[UIImage imageNamed:@"home.png"] tag:0];
tabItem.customHighlightedImage=[UIImage
imageNamed:@"Home-sel.png"];
self.tabBarItem=tabItem;
[tabItem release]; tabItem=nil;
The customHighlightedImage should be a png properly sized and colored as you
like. It will be used as-is and not recolored to the blue like normal.
