如何設置可可中的uitabbarcontroller中的單個tabbaritem圖標

Question

我被解答瞭如何爲uitabbarcontroller設置圖像。但是我的UITabBarController是意見陣列，看起來像：

  tabBarController = [[UITabBarController alloc] init];   

viewTab1controller = [[ViewTab1Controller alloc] initWithNibName:@"ViewTab1" bundle:nil]; 
viewTab1controller.title = @"Schedules"; 
navigationTab1Controller = [[[UINavigationController alloc] initWithRootViewController:viewTab1controller] autorelease]; 
[viewTab1controller release]; 

viewTab2controller = [[ViewTab2Controller alloc] initWithNibName:@"ViewTab2" bundle:nil]; 
viewTab2controller.title = @"Nearest Stop"; 
navigationTab2Controller = [[[UINavigationController alloc] initWithRootViewController:viewTab2controller] autorelease]; 
[viewTab2controller release]; 

viewTab3controller = [[ViewTab3Controller alloc] initWithNibName:@"ViewTab3" bundle:nil]; 
viewTab3controller.title = @"Routes"; 
navigationTab3Controller = [[[UINavigationController alloc] initWithRootViewController:viewTab3controller] autorelease]; 
[viewTab3controller release]; 

viewTab4controller = [[ViewTab4Controller alloc] initWithNibName:@"ViewTab4" bundle:nil]; 
viewTab4controller.title = @"Feedback"; 
navigationTab4Controller = [[[UINavigationController alloc] initWithRootViewController:viewTab4controller] autorelease]; 
[viewTab4controller release]; 

//viewTab5controller = [[ViewTab5Controller alloc] initWithNibName:@"ViewTab5" bundle:nil]; 
//navigationTab5Controller = [[[UINavigationController alloc] initWithRootViewController:viewTab5controller] autorelease]; 
//[viewTab5controller release]; 

tabBarController.viewControllers = [NSArray arrayWithObjects: 
            navigationTab1Controller, 
            navigationTab2Controller, 
            navigationTab3Controller, 
            navigationTab4Controller, 
            //navigationTab5Controller, 

他們給我在以前的答案代碼的圖像添加到tabbaritem：

 viewController.tabBarItem.image = [UIImage imageNamed:@"foo.png"]; 

然而，這並不指定特定的tabbbaritem。

如何將圖像分配給這四個選項卡中的每一個？

謝謝！ 無];

像這樣做的，你會被添加到您的標籤欄每個視圖控制器：

viewTab1controller = [[ViewTab1Controller alloc] initWithNibName:@"ViewTab1" bundle:nil]; 
viewTab1controller.title = @"Schedules"; 

navigationTab1Controller = [[UINavigationController alloc] initWithRootViewController:viewTab1controller]; 
navigationTab1Controller.tabBarItem.image = [UIImage imageNamed:@"Match.png"];
