问题描述

I have created a UITabBar and UITabBarItems without UITabBarController on it, now i want to know how to place an action on click of the UITabBarItem.What is the method i should use for action on UITabBarItem?

推荐答案

您不能直接在UITabBarItem对象上设置操作.相反,您的视图控制器应实现以下UITabBarDelegate方法:

You can't set an action on a UITabBarItem object directly. Instead, your view controller should implement the following UITabBarDelegate method:

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

当用户选择一个选项卡(即UITabBarItem)时,将调用此方法.

This method is called when the user selects a tab (i.e. UITabBarItem).
