IOS迅速创建应用程序文件夹错误 [英] IOS swift creating app folder error

问题描述

我在为 PhotoLibrary 创建文件夹时遇到了问题。
有谁知道那里有什么问题？

I got problem with creating folder for PhotoLibrary. Does anyone know what is wrong there?

            var albumPlaceholder:PHObjectPlaceholder!
            //create the folder
            NSLog("\nFolder \"%@\" does not exist\nCreating now...", albumName)
            PHPhotoLibrary.sharedPhotoLibrary().performChanges({
                let request = PHAssetCollectionChangeRequest.creationRequestForAssetCollectionWithTitle(albumName)
                albumPlaceholder = request.placeholderForCreatedAssetCollection
                },
                completionHandler: {(success:Bool, error:NSError!)in
                    NSLog("Creation of folder -> %@", (success ? "Success":"Error!"))
                    self.albumFound = (success ? true:false)
                    if(success){
                        let collection = PHAssetCollection.fetchAssetCollectionsWithLocalIdentifiers([albumPlaceholder.localIdentifier], options: nil)
                        self.assetCollection = collection?.firstObject as PHAssetCollection
                    }
            })

这段代码一直打印错误！在控制台上。提前致谢！

推荐答案

您无权访问照片库。
您需要先申请。因此，请使用以下代码：

You don't have permission to access Photo Library. You need to request it first. So use the following code for that:

PHPhotoLibrary.requestAuthorization
{ (PHAuthorizationStatus status) -> Void in
     switch (status)
     {
        case .Authorized:
            // Permission Granted
            println("Write your code here")
        case .Denied:
            // Permission Denied
            println("User denied")
        default:
            println("Restricted")
        }
    }

有关详细信息，请参阅： requestAuthorization
