Adding a "Pick from Photo Library" button to UIImagePickerController's toolbar
提问by RickiG
I am implementing a flow where the user can either select a photo from their library or take a photo using the camera. When presenting the UIImagePickerController modally I have to either go:
我正在实施一个流程，用户可以从他们的库中选择一张照片或使用相机拍照。当以模态呈现 UIImagePickerController 时，我必须要么去：
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
or
或者
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
This means presenting a "scaffolding controller" where to user can pick either their Library or the Camera. I see that most other apps with this kind of functionality go directly to the Camera controller, but displays a button for selecting from the library instead.
这意味着呈现一个“脚手架控制器”，用户可以在其中选择他们的图书馆或相机。我看到大多数其他具有这种功能的应用程序直接进入相机控制器，但会显示一个用于从库中进行选择的按钮。
All examples/tutorials I can find, including Apple's PhotoPicker source, does this empty viewController where you pick from camera or library - but all apps I check does the 'direct to camera - with the option for going to library".
我能找到的所有示例/教程，包括 Apple 的 PhotoPicker 源代码，都会在您从相机或库中选择的空视图控制器中执行此操作 - 但我检查的所有应用程序都执行“直接到相机 - 并带有转到库的选项”。
How do I add the photo library button option to the camera tool bar?
