这段代码也可以工作。把这个放到导航控制器的根控制器上:

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];

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。

这里解释的解决方案没有一个对我有效。所以我所做的就是从我来自的场景中删除标题，方法如下:

自我。标题= @"";

因此，当新场景呈现时，后面的文本不会出现。

我完全同意，这不是一个明确的解决方案，但工作，没有一个解释对我有效。

这对我来说是以前发布的答案的“简化”版本。

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] init];

backButton.title = @"Go Back";

self.navigationItem.backBarButtonItem = backButton;

记住把代码放在父视图控制器(例如，有你的表格视图或UITableViewController的视图)，而不是子视图或细节视图(例如，UIViewController)。

你可以像这样简单地本地化返回按钮字符串:

backButton.title = NSLocalizedString(@"Back Title", nil);

我发现最好是在推到下一个视图控制器之前，在导航堆栈中将当前视图控制器的标题更改为后退按钮的所需文本。

例如

self.navigationItem.title = @"Desired back button text";
[self.navigationController pushViewController:QAVC animated:NO];

然后在viewDidAppear中将标题设置回原始VC所需的标题。瞧!

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
