我的UITabBarController的didSelectViewController方法没有得到调用？ [英] My UITabBarController's didSelectViewController method is not getting called?

问题描述

这是我的代码存根为我的app-delegate.m - 它从不被调用。

Here is my code stub for my app-delegate.m -- it never gets called.

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
    NSLog(@"%s", __FUNCTION__);
}

它在此app-delegate.h中定义

It is defined in this app-delegate.h

@interface OrioleAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
    UIWindow *window;
    UITabBarController *tabBarController;
}

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

@end

推荐答案

您在 UITabBarController 和您的应用程序委托之间建立连接？

Did you make a connection between your UITabBarController and your application delegate?

- (void)applicationDidFinishLaunching:(UIApplication *)application
{
     ...
     tabBarController.delegate = self;
     ...
}
