我在iOS新，但我会提供我的覆盖导航控制器类的非常简单的答案。 我有简单的覆盖推和弹出方法，并保存以前的视图控制器的标题。抱歉在js block中进行了粘贴。有点困惑如何过去它在正常的代码块。

#import "MyCustomNavController.h" @implementation MyCustomNavController { NSString *_savedTitle; } - (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated withBackBtnTitle:(NSString *)title { _savedTitle = self.topViewController.title; self.topViewController.title = title; [super pushViewController:viewController animated:animated]; } - (UIViewController *)popViewControllerAnimated:(BOOL)animated { [self.viewControllers objectAtIndex:self.viewControllers.count - 2].title = _savedTitle; return [super popViewControllerAnimated:animated]; } @end

我发现，更改返回按钮名称最简单的方法是将视图控制器的标题设置为返回按钮的标题，然后将视图控制器导航项中的titleView替换为带有它的真实名称的自定义标签。

是这样的:

CustomViewController.m

@implementation CustomViewController

- (NSString*)title {
    return @"Back Button Title";
}

- (void)viewDidLoad {
    [super viewDidLoad];
    UILabel* customTitleView = [[UILabel alloc] initWithFrame:CGRectZero];
    customTitleView.text = @"Navigation Bar Title";
    customTitleView.font = [UIFont boldSystemFontOfSize:20];
    customTitleView.backgroundColor = [UIColor clearColor];
    customTitleView.textColor = [UIColor whiteColor];
    customTitleView.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
    customTitleView.shadowOffset = CGSizeMake(0, -1);

    [customTitleView sizeToFit];

    self.navigationItem.titleView = [customTitleView autorelease];
}

@end

这将使你的标题在UINavigationBar看起来就像它是本地的。让视图控制器能够拥有分离的标题和返回按钮标题。

在视图控制器A和B的情况下，A负责告诉它的后退按钮应该是什么样子，而B是显示的。

编辑:这也保持了后退按钮的原始外观(左边带箭头的栏按钮项)。

UIBarButtonItem *btnBack = [[UIBarButtonItem alloc]
                                   initWithTitle:@"Back" 
                                   style:UIBarButtonItemStyleBordered
                                   target:self
                                   action:@selector(OnClick_btnBack:)];
    self.navigationItem.leftBarButtonItem = btnBack;
    [btnBack release];

以下是答案:

在viewDidAppear:animated中(不是在viewDidLoad中)执行以下操作

- (void)viewDidAppear:(BOOL)animated
{
     [self.navigationController.navigationBar.backItem setTitle:@"anything"];

     // then call the super
     [super viewDidAppear:animated];
}

如果你想保持后退按钮的形状。

斯坦的回答是最好的。但它也有一个问题，当你使用带有标签栏的控制器并更改控制器的标题时，你也可以更改标签栏的标题。所以最好的答案是改变view_controller。navigationitem。只使用view_controller.navigationItem。函数中的标题。 答案在这里:(使用ARC并将它们添加到视图的viewDidLoad中)

  static NSString * back_button_title=@"Back"; //or whatever u want
  if (![view_controller.navigationItem.title isEqualToString:back_button_title]){
    UILabel* custom_title_view = [[UILabel alloc] initWithFrame:CGRectZero];
    custom_title_view.text = view_controller.navigationItem.title; // original title
    custom_title_view.font = [UIFont boldSystemFontOfSize:20];
    custom_title_view.backgroundColor = [UIColor clearColor];
    custom_title_view.textColor = [UIColor whiteColor];
    custom_title_view.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
    custom_title_view.shadowOffset = CGSizeMake(0, -1);

    [custom_title_view sizeToFit];

    view_controller.navigationItem.titleView = custom_title_view;
    view_controller.navigationItem.title = back_button_title;
  }

在我自己的使用中，我使它成为一个这样的函数，只是在viewDidLoad中有一行代码的特性。

+ (void)makeSubViewHaveBackButton:(UIViewController*) view_controller{
  static NSString * back_button_title=@"Back"; //or whatever u want
  if (![view_controller.navigationItem.title isEqualToString:back_button_title]){
    UILabel* custom_title_view = [[UILabel alloc] initWithFrame:CGRectZero];
    custom_title_view.text = view_controller.navigationItem.title; // original title
    custom_title_view.font = [UIFont boldSystemFontOfSize:20];
    custom_title_view.backgroundColor = [UIColor clearColor];
    custom_title_view.textColor = [UIColor whiteColor];
    custom_title_view.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
    custom_title_view.shadowOffset = CGSizeMake(0, -1);

    [custom_title_view sizeToFit];

    view_controller.navigationItem.titleView = custom_title_view;
    view_controller.navigationItem.title = back_button_title;
  }
}

Most of solutions kills the original style of BackButton (The left arrowed bar button) while adding a usual button with desired title. So to keep the original style there are 2 ways: 1st: To use undocumented button style (110 or something like that) which I prefer not to do. But if you want you could find how to do it here, on stackoverflow. 2nd: To use I the Trenskow's idea. I liked it and I use it a bit changed. Instead of overriding - (NSString*)title I've decided to keep the original title in the following way (which allows me to use nib's titles as well as given title at push state btw).

- (void)viewDidLoad {
    [super viewDidLoad];
    static NSString * backButtonTitle=@"Back"; //or whatever u want

    if (![self.title isEqualToString:backButtonTitle]){

        UILabel* customTitleView = [[UILabel alloc] initWithFrame:CGRectZero];
        customTitleView.text = self.title; // original title
        customTitleView.font = [UIFont boldSystemFontOfSize:20];
        customTitleView.backgroundColor = [UIColor clearColor];
        customTitleView.textColor = [UIColor whiteColor];
        customTitleView.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
        customTitleView.shadowOffset = CGSizeMake(0, -1);

        [customTitleView sizeToFit];

        self.navigationItem.titleView = [customTitleView autorelease];
        self.title = backButtonTitle; 
    }
}

这个解决方案效果很好，看起来很自然。此外，如果在viewDidLoad方法中使用它，它可以防止执行超过1次。 我也试过杰塞德克的解决方案，但看起来很糟糕。它导致可见的用户标题栏的变化，从原来的BackButton的期望和回来。
