推荐答案
正如您在评论中所说,您使用模态控制器
As you said in your comment you use a modal controller
在 viewWillappear
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style: UIBarButtonItemStyleBordered target:self action:@selector(Back)];
self.navigationItem.leftBarButtonItem = backButton;
并且
- (IBAction)Back
{
[self dismissViewControllerAnimated:YES completion:nil]; // ios 6
}
