问题描述

如何让 UINavigation 控制器导航到前一个视图而不是前一个视图.基本上我希望它跳回 2 个位置而不是默认位置.

How would I go about having a UINavigation controller navigate not to the previous view but the view before that. Basically I would like it to jump back 2 places instead of the default one.

我敢肯定，这是非常规的，但我现在只需要这样做.

This is unconventional I'm sure, but I just need to do it for now.

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

感谢您的帮助.

推荐答案

设置:

self.navigationItem.backBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(goBack)] autorelease];

然后创建一个方法-goBack

-(void)goBack
{
   UIViewController *ctrl = [self.navigationController.viewControllers objectAtIndex:self.navigationController.viewControllers.count - 2];
   [self.navigationController popToViewController:ctrl animated:YES];
}
