objective-c - 如何将UINavigationBar后退按钮的标题更改为 "Back"

Question

当我将 View 推送到导航 Controller 时，后退按钮的标题会设置为前一个 View 的标题。如何让后退按钮只说“后退”？

Answer 1

在你的viewwillappear中写下这段代码:

UIBarButtonItem *_backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleDone target:nil action:nil];
self.navigationItem.backBarButtonItem = _backButton;
[_backButton release];
_backButton = nil;
