我正在尝试以编程方式更改导航栏的标题，但我使用的代码不起作用。

首先通过查看当前控制器在导航堆栈上的索引
NSLog(@"%@", self.navigationController.viewControllers );
after finding the index of current ViewController let say 1.
找到当前 ViewController 的索引后，假设为 1。
UINavigationController *navCon = (UINavigationController*) [self.navigationController.viewControllers objectAtIndex:1];
navCon.navigationItem.title = @"Hello";

You can use built in method setTitlenow in XCode[self setTitle:@"title"]
or self.title=@"title"
inside its viewController.
您现在可以在 XCode或其viewController 中使用内置方法setTitle。[self setTitle:@"title"]self.title=@"title"
