cocoa-touch - 如何在可可的 uitabbarcontroller 中设置单个 tabbaritem 图标

Question

有人回答了我如何为 uitabbarcontroller 一般设置图像。但是我的 uitabbarcontroller 是一组视图，如下所示：

          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, 

我在上一个答案中获得了将图像添加到 tabbaritem 的代码：

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

但是，这并没有指定特定的 tabbbaritem。

如何将图像分配给这 4 个选项卡中的每一个？

谢谢！零];

对要添加到标签栏的每个视图控制器执行以下操作：

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

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