無法自定義iOS5中的標籤欄

我在iOS 5中有一個選項卡，並希望針對所選狀態和未選狀態爲TabBarButton創建圖像。下面是代碼：無法自定義iOS5中的標籤欄

BOOL isIOS5 = [[[UIDevice currentDevice] systemVersion] floatValue] >= 5.0; 

    if(isIOS5) 
    { 
     //[tabBarController.tabBar setBackgroundImage:[UIImage imageNamed:@"Tab-bg"]]; 
     // [tabBarController.tabBar setSelectionIndicatorImage:[UIImage imageNamed:@"Cell-bg"]]; 

     [[tabBarController.tabBar.items objectAtIndex:0] setFinishedSelectedImage:[UIImage imageNamed:@"list-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"list-menu"]]; 
     [[tabBarController.tabBar.items objectAtIndex:1] setFinishedSelectedImage:[UIImage imageNamed:@"gallery-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"gallery-menu"]]; 
     [[tabBarController.tabBar.items objectAtIndex:2] setFinishedSelectedImage:[UIImage imageNamed:@"map-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"map-menu"]]; 
     [[tabBarController.tabBar.items objectAtIndex:3] setFinishedSelectedImage:[UIImage imageNamed:@"submit-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"submit-menu"]]; 
     [[tabBarController.tabBar.items objectAtIndex:4] setFinishedSelectedImage:[UIImage imageNamed:@"search-menu-selected"] withFinishedUnselectedImage:[UIImage imageNamed:@"search-menu"]]; 
    }

即圖像的非Retina顯示屏44px高度，他們應該是足夠的，以填補空間

的問題是，dont't將圖像從頂部至底部：在tabbar的底部還有一些空間沒有填充。有沒有人有過這個問題？
