NSPhotoLibraryUsageDescription key must be present in Info.plist to use camera roll

提问by Murat Ozgul

Recently I started to get this error:

最近我开始收到这个错误：

NSPhotoLibraryUsageDescription key must be present in Info.plist to use camera roll.

NSPhotoLibraryUsageDescription 键必须存在于 Info.plist 中才能使用相机胶卷。

I am using React Native to build my app (I am not familiar with ios native development) and I don't know how to add this key to Info.plist

我正在使用 React Native 来构建我的应用程序（我不熟悉 ios 本机开发）并且我不知道如何将此键添加到 Info.plist

Can you post an example? Thanks

I am using npm package "react-native-camera-roll-picker": "^1.1.7"

Thanks @rmaddy, I added this just after other key-string pairs in Info.plist and fixed the problem:

谢谢@rmaddy，我在 Info.plist 中的其他键字符串对之后添加了这个并解决了这个问题：

<key>NSPhotoLibraryUsageDescription</key>
<string>Photo Library Access Warning</string>

Edit:

编辑：

I also ended up having similar problems on different components of my app. Ended up adding all these keys so far (after updating to Xcode8/iOS10):

我也最终在我的应用程序的不同组件上遇到了类似的问题。到目前为止，最终添加了所有这些键（更新到 Xcode8/iOS10 后）：

<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app does not require access to the microphone.</string>
<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>

You need to paste these two in your info.plist, The only way that worked in iOS 11 for me.

您需要将这两个粘贴到 info.plist 中，这是在 iOS 11 中对我有用的唯一方法。

    <key>NSPhotoLibraryUsageDescription</key>
    <string>This app requires access to the photo library.</string>

    <key>NSPhotoLibraryAddUsageDescription</key>
    <string>This app requires access to the photo library.</string>

For camera access use:

对于相机访问使用：

<key>NSCameraUsageDescription</key>
<string>Camera Access Warning</string>

回答by Shanu Singh

In order to save or retrieve an image from the camera roll. Additionally, you need to ask the user for the permission otherwise you'll get this error or your app may get crashed. To save yourself from this add this into your info.plist

为了从相机胶卷中保存或检索图像。此外，您需要征求用户的许可，否则您会收到此错误或您的应用程序可能会崩溃。为了避免这种情况，请将其添加到您的 info.plist 中

<key>NSPhotoLibraryAddUsageDescription</key>
<string>This app requires read and write permission from the user.</string>

In the case of Xamarin.iOS

对于 Xamarin.iOS

 if you're adding it from the generic editor then "Privacy - Photo Library Additions Usage Description" will be the given option you will find out instead of "NSPhotoLibraryAddUsageDescription".

回答by Moises Hilario

If you added the key-string pairs in Info.plist (see Murat's answer above) and still getting the error, try to check if the target you're currently working on has the keys.

如果您在 Info.plist 中添加了键字符串对（请参阅上面的 Murat 的回答）并且仍然收到错误，请尝试检查您当前正在处理的目标是否具有键。

In my case I had 2 targets (dev and development). I added the keys in the editor, but it only works for the main target and I was testing on development target. So I had to open XCode, click on the project > Info > Add the key-pair for the development target there.

就我而言，我有 2 个目标（开发和开发）。我在编辑器中添加了键，但它只适用于主要目标，我正在测试开发目标。所以我必须打开 XCode，点击项目 > 信息 > 在那里添加开发目标的密钥对。
