删除UITabBarItem [英] Remove UITabBarItem

问题描述

如何从UITabBar中删除UITabBarItem?

我没有尝试任何事情，因为我没有从Google搜索或UITabBar，UITabBarController或UITabBarItem的文档中找到任何东西.

I haven't tried anything, because I haven't found anything from Google searches or the documentation for UITabBar, UITabBarController, or UITabBarItem.

提前谢谢！ :)

推荐答案

UITabBar has an NSArray collection of items. Since the items property is an NSArray and not an NSMutableArray, you'd have to construct a new NSArray from the existing one devoid of the object you want to remove, then set the items property to the new array.

/* suppose we have a UITabBar *myBar, and an int index idx */
NSMutableArray *modifyMe = [[myBar items] mutableCopy];
[modifyMe removeObjectAtIndex:idx];
NSArray *newItems = [[NSArray alloc] initWithArray:modifyMe];
[myBar setItems:newItems animated:true];
