有没有办法将所有导航栏后退按钮的标题全局更改为“返回”按钮。 [英] Is there a way to globally change title of all navigtion bar back button to "Back"

问题描述

在所有视图控制器中更改它是单调乏味的

It's tedious to change it in all view controller

我可以全局更改吗？

推荐答案

您可以使用的是一个类别：

What you can use is a category:

UINavigationItem + MyBackButton.h

UINavigationItem+MyBackButton.h

@interface UINavigationItem (MyBackButton)

@end

UINavigationItem + MyBackButton.m

UINavigationItem+MyBackButton.m

#import "UINavigationItem+MyBackButton.h"

@implementation UINavigationItem (MyBackButton)

-(UIBarButtonItem*)backBarButtonItem
{
    UIBarButtonItem *backButton = [[UIBarButtonItem alloc] 
                                   initWithTitle: @"Back Button Text" 
                                   style: UIBarButtonItemStyleBordered
                                   target: nil action: nil];

    return [backButton autorelease];
}
@end

将这两个文件添加到项目中，你就是完成。
为了提高效率，应在此添加ivar和延迟加载。

Add this two files to the project and you are done. To be more efficient ivar and lazy loading should be added here.
