Question

我从之前的问题中得到了一些建议，并对代码进行了相当多的修改。我仍在尝试检测何时触摸标签栏项目。如果所选索引为零，则应在nslog中返回“moo”。可能会遗漏一个小细节。

查看控制器1

     TUHomeViewController *homeViewController = [[TUHomeViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *homeNavigationController = [[UINavigationController alloc] initWithRootViewController:homeViewController];
homeNavigationController.tabBarItem = [[DSTabBarItem alloc] initWithFinishedSelectedImage:[UIImage imageNamed:@"home"] 
                                                            finishedUnselectedImage:[UIImage imageNamed:@"home1"]
                                                                                 iconSize:CGSizeMake(76, 59)
                                                                                tag:0];
[tabBarViewControllers addObject:homeNavigationController];

查看控制器2.h

     @interface viewcontroller2 : UIViewController<UIWebViewDelegate,UITabBarControllerDelegate>{

       }

查看控制器2

   - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController{

if(self.tabBarController.selectedIndex == 0){
    NSLog(@"MOO");
 return(TRUE);

}
return(FALSE);
 }

  - (void)viewDidLoad {
  [super viewDidLoad];
   self.delegate = self;
   }

Answer 1

将您的代表设置为自己：

[tabBarViewControllers setDelegate:self];

Answer 2

只需在appdelegare（你正在创建的地方）实现你的tabBar委托

self.objTabBarController.delegate=self;

在appdelegate中实现其委托方法

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController
{
    NSLog(@"MOO");
    return YES;
}

我对标签栏代表做错了什么？
