如何在嵌入式 UIImagePickerController 中隐藏导航栏 [英] How to hide Navigation Bar in embedded UIImagePickerController

问题描述

我正在尝试将 UIImagePickerController 作为普通 UIViewController 中的子视图呈现.

I'm trying to present UIImagePickerController as a subview in ordinary UIViewController.

我面临的问题是我无法隐藏内部导航栏(带有Chwile"标题和Anuluj"按钮).它看起来像这样:

The problem I'm facing is that I'm unable to hide the inner navigation bar (with "Chwile" title and "Anuluj" button). It looks something like this:

我尝试用我的自定义控制器子类化 UIImagePickerController.我还尝试设置 NavigationBar 属性的样式并获得以下结果:

I tried subclassing UIImagePickerController with my custom controller. I also tried to style the NavigationBar property and achieved the following result:

但是，我想完全删除导航栏.我试图在 ViewWillAppear、ViewDidLoad<中调用 SetNavigationBarHidden(true, true); 和 NavigationController.SetNavigationBarHidden(true, true);/code> 和自定义图像选择器控制器的 ViewDidAppear，但没有结果.

However, I'd like to remove the Navigation Bar entirely. I tried to call SetNavigationBarHidden(true, true); and NavigationController.SetNavigationBarHidden(true, true); in ViewWillAppear, ViewDidLoad and also ViewDidAppear of custom image picker controller, but with no result.

您知道如何完全删除导航栏吗?swift 或 obj-c 中的解决方案对我来说也很完美.

Do you know how to remove the nav bar entirely? The solution in swift or obj-c is also perfect for me.

    private void PresentImagePicker(UIImagePickerControllerSourceType type)
    {
        imagePicker = new CustomImagePickerController
        {
            SourceType = type,
            AllowsEditing = false,
        };

        imagePicker.FinishedPickingMedia += OnImagePickerFinishedPickingMedia;
        imagePicker.Canceled += OnImagePickerCancelled;

        AddChildViewController(imagePicker);

        ContentView.AddSubview(imagePicker.View);
        imagePicker.View.Frame = Content.Bounds;
        imagePicker.View.AutoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight;

        imagePicker.DidMoveToParentViewController(this);
    }

推荐答案

您可以像这样简单地使用presentViewController，而不是将子视图添加到父视图和管理框架:

Instead of adding subview to parent view and managing frames, you can simply use presentViewController like this:

self.present(imagePicker, animated: true, completion: nil)

因此，您需要删除以下几行并用上面的一行替换它们:

So, you need to remove following these lines and replace them with just one line as above:

        AddChildViewController(imagePicker);
        ContentView.AddSubview(imagePicker.View);
        imagePicker.View.Frame = Content.Bounds;
        imagePicker.View.AutoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight;

        imagePicker.DidMoveToParentViewController(this);

它会正常工作
