You can change the title of the edit button like this:-
您可以像这样更改编辑按钮的标题：-
- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
// Make sure you call super first
[super setEditing:editing animated:animated];
if (editing)
{
self.editButtonItem.title = NSLocalizedString(@"Cancel", @"Cancel");
}
else
{
self.editButtonItem.title = NSLocalizedString(@"Edit", @"Edit");
}
}
its working like edit:-
它的工作方式就像编辑：-

Building on Nitin's answerI suggest a slightly different approach that uses the built in UIButtonBarsystem items.
基于Nitin 的回答，我建议使用一种稍微不同的方法来使用内置UIButtonBar系统项。
This will give your UI the system look & feel. For example, the standard "Done" button to cease editing should have a specific boldlook on iOS 8. Apple might change these stylings in future. By using the system defined buttons your app will pick up the current aesthetic automatically.
这将为您的 UI 提供系统外观和感觉。例如，用于停止编辑的标准“完成”按钮在 iOS 8 上应该具有特定的粗体外观。Apple 将来可能会更改这些样式。通过使用系统定义的按钮，您的应用程序将自动选择当前的美学。
This approach also provides you with free string localisation. Apple have already translated the system button titles for you in to the dozens of languages that iOS supports.
这种方法还为您提供了免费的字符串本地化。Apple 已经为您将系统按钮标题翻译成 iOS 支持的数十种语言。
Here's the code I've got:
这是我得到的代码：
-(IBAction) toggleEditing:(id)sender
{
[self setEditing: !self.editing animated: YES];
}
-(void) setEditing:(BOOL)editing animated:(BOOL)animated
{
[super setEditing: editing animated: animated];
const UIBarButtonSystemItem systemItem =
editing ?
UIBarButtonSystemItemDone :
UIBarButtonSystemItemEdit;
UIBarButtonItem *const newButton =
[[UIBarButtonItem alloc]
initWithBarButtonSystemItem: systemItem
target: self
action: @selector(toggleEditing:)];
[self.navigationItem setRightBarButtonItems: @[newButton] animated: YES];
}
The example here is for the case where your UIViewControlleris hosted in a UINavigationControllerand so has a UINavigationIteminstance. If you're not doing this, you'll need to update the bar item in an appropriate way.
此处的示例适用于您UIViewController托管在 a 中UINavigationController并因此有一个UINavigationItem实例的情况。如果您不这样做，则需要以适当的方式更新栏项目。
In your viewDidLoaduse the following call to configure the edit button ready for use:
在您viewDidLoad使用以下调用来配置准备使用的编辑按钮：
[self setEditing: NO animated: NO];
