ios - PresentViewController 在 iOS 中隐藏导航栏

Question

当我呈现 PresentViewController 以导航屏幕时，我试图显示导航 Controller 。我解决了这个问题，但我遇到了另一个问题。问题是当我按下一个屏幕时，时间后退按钮在带有导航 Controller 的下一个屏幕上可见。但是当我尝试 PresentViewController 时，那个时候导航栏是可见的但不是后退按钮。

这是我的代码:

 - (IBAction)clickMeAction:(id)sender
 {
    ViewController1 *viewcontrol = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewID"];
    //[self.navigationController pushViewController:viewcontrol animated:YES]; // this is for push to viewcontroller


    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewcontrol];
    [self presentViewController:navigationController animated:YES completion:nil]; // This is for modalviewcontroller
 }

这是我的输出:

Answer 1

方法一:

[navigationController presentViewController:navigationController animated:YES completion:^{
             [navigationController setNavigationBarHidden:YES animated:NO];
        }];

方法二:在presentViewController中

- (void)viewWillAppear:(BOOL)animated {
        [super viewWillAppear:animated];
        self.navigationController.navigationBarHidden = YES;
}
