使用下面的代碼來執行：

[[UITabBar appearance] setBackgroundImage:tabBarBackground]; 
[[UITabBar appearance]setSelectionIndicatorImage:[UIImage imageNamed:@"footer-hover-bg.png"]]; 

if(IS_IOS_7) 
{ 
    [[appDelegate.tabBarController tabBar] setSelectionIndicatorImage:[UIImage imageNamed:@"footer-hover-bg.png"]]; 
    [[UITabBar appearance] setTintColor:[UIColor blackColor]]; 
} 
appDelegate.tabBarController.tabBar.frame = CGRectMake(0, 20, 320, 50); 
appDelegate.tabBarController.delegate=self; 

UIView *view=[[UIView alloc]initWithFrame:CGRectMake(0, -20, 320, 600)]; 

viewControllers = [[NSMutableArray alloc] init]; 

MainViewController *view1 = [[MainViewController alloc] init]; 
UINavigationController *nav1=[[UINavigationController alloc]initWithRootViewController:view1]; 
[viewControllers addObject:nav1]; 

ViewController1 *view2 = [[ViewController1 alloc] init]; 
UINavigationController *nav2=[[UINavigationController alloc]initWithRootViewController:view2]; 
[viewControllers addObject:nav2]; 

[appDelegate.tabBarController setViewControllers:viewControllers]; 

appDelegate.tabBarController.tabBarController.view.frame=CGRectMake(0, 0, 320, 480); 
[view addSubview:appDelegate.tabBarController.view]; 

[self.view addSubview:view]; 

UITabBarItem *tabBarItem1 = [appDelegate.tabBarController.tabBar.items objectAtIndex:0]; 
UITabBarItem *tabBarItem2 = [appDelegate.tabBarController.tabBar.items objectAtIndex:1]; 


[tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:[arraySelectedImages objectAtIndex:0]] withFinishedUnselectedImage:[UIImage imageNamed:[arrayUnselectedImages objectAtIndex:0]]]; 
[tabBarItem2 setFinishedSelectedImage:[UIImage imageNamed:[arraySelectedImages objectAtIndex:1]] withFinishedUnselectedImage:[UIImage imageNamed:[arrayUnselectedImages objectAtIndex:1]]];
