@interface CustomTabBarItem : UITabBarItem 
{
    UIImage *customHighlightedImage;
    UIImage *customStdImage;
}

@property (nonatomic, retain) UIImage *customHighlightedImage;
@property (nonatomic, retain) UIImage *customStdImage;

@end


//====== implementation file .m ========

#import "CustomTabBarItem.h"

@implementation CustomTabBarItem

@synthesize customHighlightedImage;
@synthesize customStdImage;

- (void) dealloc
{
    [customHighlightedImage release]; customHighlightedImage=nil;
    [customStdImage release]; customStdImage=nil;  
    [super dealloc];
}

-(UIImage *) selectedImage
{
    return self.customHighlightedImage;

    tabItem.customHighlightedImage=[UIImage imageNamed:@"but-home-active"];
    tabItem.customStdImage=[UIImage imageNamed:@"but-home"];  
   
    UIEdgeInsets titleInsets = UIEdgeInsetsMake(2.0, 0.0, -5.0, 0.0);
    tabItem.imageInsets = titleInsets;
   
    self.tabBarItem=tabItem;
    [tabItem release];
    tabItem=nil; 
   
    [super awakeFromNib];
