我有一个标签栏，我试图检测它是否在视图控制器 2 中被触摸

问题描述

基本上我在视图控制器一中有一个标签栏.我正在尝试检测是否在视图控制器 2 内触摸了此 tabaritem.执行此类任务的最佳方法是什么?如果您愿意，我可以发布更具体的代码.

Basically I have a tab bar in view controller one. I am trying to detect if this tabaritem is touched inside view controller 2. What is the best method to perform such a task? I can post more specific code if you would like.

视图控制器 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];

视图控制器 2

推荐答案

你应该使用 UITabBarControllerDelegate.请参阅:http://developer.apple.com/library/ios/#documentation/uikit/reference/UITabBarControllerDelegate_Protocol/Reference/Reference.html

You should use UITabBarControllerDelegate. See: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITabBarControllerDelegate_Protocol/Reference/Reference.html

更具体地说，看看

tabBarController:didSelectViewController:

告诉委托人用户在标签栏中选择了一个项目."

"Tells the delegate that the user selected an item in the tab bar."
