iphone - 导航栏上有超过 1 个 rightBarButtonItem

Question

我想在导航栏上有两个 rightBarButtonItems。一个用于编辑，另一个用于添加。

显然我无法使用 Interface Builder 来实现它。

有人知道如何以编程方式做到这一点吗？谢谢!

它现在包含在 iOS 5 中，称为 rightBarButtonItems，注意复数

这是来自 apple docs 的文本:

rightBarButtonItems

An array of custom bar button items to display on the right side of the navigation bar when the receiver is the top navigation item.

@property(nonatomic, copy) NSArray *rightBarButtonItems

Discussion

This array can contain 0 or more bar button items to display on the right side of the
navigation bar. Items are displayed right-to-left in the same order as they appear in the array. Thus, the first item in the array is the rightmost item and other items are added to the left of the previous item.

If there is not enough room to display all of the items in the array, those that would overlap the title view (if present) or the buttons on the left side of the bar are not
displayed.

The first item in the array can also be set using the rightBarButtonItem property.

Declared In UINavigationBar.h

以下是我在导航栏右侧实现搜索图标和编辑图标的方法:

UIBarButtonItem *searchButton         = [[UIBarButtonItem alloc]
                                         initWithBarButtonSystemItem:UIBarButtonSystemItemSearch
                                         target:self
                                         action:@selector(searchItem:)];

UIBarButtonItem *editButton          = [[UIBarButtonItem alloc] 
                                         initWithBarButtonSystemItem:UIBarButtonSystemItemEdit
                                         target:self action:@selector(editItem:)];

self.navigationItem.rightBarButtonItems =
[NSArray arrayWithObjects:editButton, searchButton, nil];
