iphone – tabBar didSelectItem似乎没有用

@interface TabBarController : UIViewController <UIApplicationDelegate,UITabBarDelegate,UITabBarControllerDelegate>{

    IBOutlet UITabBarController *tabBarController;

}

-(void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item;

@property (nonatomic,retain) IBOutlet UITabBarController *tabBarController;

@end

在我的主文件中,我有这个：

@synthesize tabBarController;

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

-(void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item{
    NSLog(@"rawr"); 
}

- (void)viewDidUnload {
    [super viewDidUnload];
}

- (void)dealloc {
    [tabBarController release];
    [super dealloc];
}


@end

我已将tabbarcontroller作为委托连接到接口构建器中的文件所有者,但它仍然从不调用didSelectItem方法.

这里有什么我想念的吗？

我已经添加了tabBarController.delegate = self;它仍然无法正常工作.
