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

也许我过于简单了，但从苹果的文档中，措辞是:

如果一个自定义栏按钮项没有被任何一个视图控制器指定，则使用一个默认的返回按钮，并且它的标题被设置为前一个视图控制器的title属性的值——也就是说，在堆栈的下一层的视图控制器。

上面标记为正确的解决方案设置了来自父控制器的默认按钮项。这是正确的答案，但我正在通过改变自我来解决问题。在将新控制器推送到NavigationController堆栈之前，UIViewController的title属性。

这将自动更新后退按钮在下一个控制器上的标题，只要你设置了self。标题回到什么它应该在viewWillAppear我不能看到这个方法造成太多的问题。

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。

斯威夫特版本:

在你的子ViewController中:

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.navigationBar.backItem?.title = "TEXT"
}

self.navigationController.navigationBar.backItem.title = @"TEXT";

在Swift中:

self.navigationController?.navigationBar.backItem?.title = "TEXT"

这应该放在调用名为NewTitle的ViewController的方法中。 就在push或popViewController语句之前。

UIBarButtonItem *newBackButton = 
        [[UIBarButtonItem alloc] initWithTitle:@"NewTitle" 
                                         style:UIBarButtonItemStyleBordered 
                                        target:nil 
                                        action:nil];
[[self navigationItem] setBackBarButtonItem:newBackButton];
[newBackButton release];
