标题: ios - UIDocumentPickerViewController - 隐藏位置按钮

我正在开发一个应用程序，该应用程序能够从其他云资源导入音频文件，这些资源提供 UIDocumentPickerViewControllerExtenstion 来选择文件，但左上角有一个位置按钮，我想删除它。

下面是我的代码:

let menupicker = UIDocumentMenuViewController(documentTypes: [kUTTypeAudio as String], in: .import)
menupicker.delegate = self
self.present(menupicker, animated: true, completion: nil)



func documentMenu(_ documentMenu: UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {
    documentPicker.delegate = self
    documentPicker.navigationItem.leftBarButtonItem = nil
    self.present(documentPicker, animated: true) { 
        documentPicker.navigationItem.leftBarButtonItem = nil
        documentPicker.navigationItem.backBarButtonItem = nil
        documentPicker.navigationItem.hidesBackButton = true
    }
}

Best Answer-推荐答案

我正在寻找相同的解决方案，但找不到。根据我的理解，这是不可能的。 如果你遍历 UIDocumentPickerViewController，它实际上有一个类型为“_UIResilientRemoteViewContainerViewController”的 subview Controller

let picker = UIDocumentPickerViewController(documentTypes: supportDocTypes, in: .import)
picker.delegate = self
present(picker, animated: true) {
    print(picker.childViewControllers) // you will get something like this: [<_UIResilientRemoteViewContainerViewController: 0x102e956c0>]
}

这是无法访问的，但是我们可以通过循环访问它，最终您将获得一些其他私有(private)组件，例如_RemoteView。
