【问题描述】：
我在项目的 info.plist 文件中添加了 NSPhotoLibraryAddUsageDescription 和 NSPhotoLibraryUsageDescription。 尝试创建相册或将图像添加到照片库时出现以下错误
此应用程序已崩溃，因为它试图在没有使用说明的情况下访问隐私敏感数据。应用的 Info.plist 必须包含一个 NSPhotoLibraryUsageDescription 键和一个字符串值，向用户解释应用如何使用这些数据。
我已经尝试了一些像 PhotosHelper.as 的快速库来做到这一点，但我仍然面临同样的问题
以下是我正在关注的代码
import UIKit
import Photos
class PhotoLibraryManager
{
private class func fetchAlbumWithName(albumName:String)->PHAssetCollection?
{
let fetchPredicate = PHFetchOptions()
fetchPredicate.predicate = NSPredicate(format: "title == '" + albumName + "'")
let fetchResult = PHAssetCollection.fetchAssetCollections(with: PHAssetCollectionType.album, subtype: PHAssetCollectionSubtype.albumRegular, options: fetchPredicate)
return fetchResult.firstObject
}
/**
This function requests for authorization to use the photo gallery and adds the image in the album both of which are specified.If the album does not exist it creates a new one and adds the image in that
- Parameters:
- image:The image to be inserted
- albumName:The name of the album in which the image is to be inserted
*/
class func saveImageToPhone(image:UIImage,albumName:String)
{
PHPhotoLibrary.requestAuthorization({(status:PHAuthorizationStatus)->Void in
switch status
{
case PHAuthorizationStatus.authorized:
insertImageAfterAuthorization(image: image,albumName: albumName)
default:
print("Unable To Access Photo Library")
}
})
}
/**
This function fetches the specified album from the photo library if present or creates a new one
- Parameters:
- image:The image to be inserted
- albumName:The name of the album in which the image is to be inserted
*/
private class func insertImageAfterAuthorization(image:UIImage,albumName:String)
{
let album = fetchAlbumWithName(albumName: albumName)
guard let albumToBeInserted = album else{
print("Creating A New Album \(albumName)")
PHPhotoLibrary.shared().performChanges({
PHAssetCollectionChangeRequest.creationRequestForAssetCollection(withTitle: albumName)
}, completionHandler: {(success:Bool,error:Error?)->Void in
guard let errorObj = error else{
let album = fetchAlbumWithName(albumName: albumName)
guard let createdAlbum = album else{
print("Album Not Created")
return
}
addImageIntoAlbum(image: image,album: createdAlbum)
return
}
print(errorObj.localizedDescription)
return
})
return
}
addImageIntoAlbum(image: image,album: albumToBeInserted)
}
/**
This function adds an image into the album specifed
- Parameters:
- image:The image to be added
- album:The album in which the image is to inserted
*/
private class func addImageIntoAlbum(image:UIImage,album:PHAssetCollection)
{
PHPhotoLibrary.shared().performChanges({
let imgCreationRequest = PHAssetChangeRequest.creationRequestForAsset(from: image)
print(imgCreationRequest)
let albumRequest = PHAssetCollectionChangeRequest(for: album)
guard let albumSpecificationRequest = albumRequest , let placeholderObjForImg = imgCreationRequest.placeholderForCreatedAsset else{
print("Image Could Not Be Added")
return
}
let arrAlbumSpecificationRequest:NSArray = [placeholderObjForImg]
albumSpecificationRequest.addAssets(arrAlbumSpecificationRequest)
// albumSpecificationRequest.addAssets([placeholderObjForImg])
}, completionHandler: {(success:Bool,error:Error?)->Void in
guard let errorObj = error else{
return
}
print(errorObj.localizedDescription)
})
}
}
这是我的 info.plist

提前感谢您的帮助。
【问题讨论】：
-
那么，你是否在 info.plist 中添加了 NSPhotoLibraryUsageDescription 键？
-
更新您的问题，显示您的 Info.plist 的相关部分。
-
这可能是 plist 问题而不是代码问题。正如 rmaddy 所说，请出示您的 plist。
-
您为 NSCameraUsageDescription 添加的字符串值是多少？
-
我用 info.plist 文件更新了问题
