iphone - UINavigationController 中的 "title"问题

Question

我在标题和 UINavigationController 方面遇到问题。我在 UIViewControllerCurrent 使用以下代码，当我从 NextViewController 返回时，NavBar 的标题仍然是“Previous”。任何人都可以帮我解决这个问题吗？谢谢。

[self setTitle:@"Previous"]; 
NextViewController *controller = [[NextViewController alloc] init]; 
[[self navigationController] pushViewController:controller animated:YES]; 
[controller release], controller = nil; 

- (void)viewWillAppear:(BOOL)animated; {     
[self setTitle:@"Real Title"];     
[super viewWillAppear:animated]; } 

Answer 1

我会尝试交换两条线路

[self setTitle:@"Real Title"];     
[super viewWillAppear:animated];

让你得到

[super viewDidAppear:animated];
[self setTitle:@"Real Title"];

我会将这些放入 viewDidAppear。
