使用推送通知启动应用程序时隐藏 UINavigationBar

Question

我有一个ViewController。通常我用

启动它

MyBookingDetailedViewController * vcNavigate = [self.storyboard instantiateViewControllerWithIdentifier:@"MyBookingDetailedViewController"];
vcNavigate.bookId = [booking.bookingId intValue];
vcNavigate.status = booking.bookingStatus;

现在我尝试在用户单击 pushNotification 时打开它。我所做的是在 AppDelegate 文件的 didRecieveRemoteNotification 中添加以下内容。

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;

MyBookingDetailedViewController *booking = (MyBookingDetailedViewController*)[mainStoryboard instantiateViewControllerWithIdentifier: @"MyBookingDetailedViewController"];
booking.bookId = [notificationId intValue];
booking.status = notificationStatus;

[navigationController pushViewController:booking animated:YES];

但是出现的时候，顶部导航栏是隐藏的。我不能回去，它只是视图而已。

Answer 1

您可以将以下代码放入 MyBookingDetailedViewController

- (void) viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:animated];
}

Answer 2

请使用下面的代码并在视图中应用此代码，它可能对您有所帮助..

[self.navigationController.navigationBar setTranslucent:NO];
self.extendedLayoutIncludesOpaqueBars=NO;
