从 pushViewController 视图设置后退按钮

Question

我有一个viewControllerA，可不可以我预先设置viewControllerB的后退键，按下去的时候

Controller *B = [Controller viewControllerFromStoryboardWithProfile: profile editMode: NO];

    UIBarButtonItem *newBackButton =
    [[UIBarButtonItem alloc] initWithTitle:@"Home"
                                     style:UIBarButtonItemStyleBordered
                                    target:nil
                                    action:nil];

    [B.navigationItem setBackBarButtonItem:newBackButton];

    [self.navigationController pushViewController:B animated:YES];

是这样的吗？

Answer 1

试试这个代码：

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Home"
                                 style:UIBarButtonItemStyleBordered
                                target:nil
                                action:nil];

self.navigationItem.backBarButtonItem = backButton;
[backButton release];

[self.navigationController pushViewController:anotherViewController];
