在 iOS 台设备上访问应用内购买

Question

我正在开发一个 iOS 应用程序，其中包含一个应用程序内购买项目，该项目包含一个下载到用户设备的 PNG 文件。

从我查看日志语句可以看出，文件已成功下载到此目录：

/var/mobile/Containers/Data/Application/ABC43D27-B79C-486C-AE39-F34BF6EF8658/Documents/

如何将文件移动到用户设备上用户能够访问文件的位置，例如用户的 iCloud 存储空间？

如果这有用，下面是我下载文件的代码。

func paymentQueue(queue: SKPaymentQueue, updatedDownloads downloads: [SKDownload]) {
    for download:AnyObject in downloads {
        if let down:SKDownload = download as? SKDownload {
            switch down.downloadState {
            case .Active:
                NSLog("progress %f", down.progress)
                NSLog("remaining %f", down.timeRemaining)
                NSLog("Active")
                break
            case .Cancelled:
                NSLog("%@", "download cancelled")
                break
            case .Failed:
                NSLog("%@", "download failed")
                textView.text = "Download Failed"
                break
            case .Finished:
                NSLog("Finished")
                let source = down.contentURL?.relativePath
                //var dict = NSMutableDictionary(contentsOfFile: (source! as NSString).stringByAppendingPathComponent("ContentInfo.plist"))
                let pathToDownloadsFolder = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
                //let pathToDownloadsFolder = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first!
                let content:String =
                    (pathToDownloadsFolder as NSString).stringByAppendingPathComponent("bonus_brune_image.png")
                //let content:String = pathToDownloadsFolder.URLByAppendingPathComponent("bonus_brune_image.png")
                    self.copyPathToDownloadsFolder(source!, target: content)
                    SKPaymentQueue.defaultQueue().finishTransaction(down.transaction)
                    break
            case .Paused:
                NSLog("%@", "download paused")
                break
            case .Waiting:
                NSLog("%@", "download waiting")
                break
            }
        }
    }
}

func copyPathToDownloadsFolder(source:String, target:String) {
    NSLog("Source is %@", source)
    NSLog("Target is %@", target)

    let filemgr:NSFileManager = NSFileManager.defaultManager()

    do {
    try filemgr.copyItemAtPath(source, toPath: target)
        NSLog("Success: file is now in %@", target)
    } catch let e as NSError {
        NSLog(String(e))
    }
}

所以我发现解决办法是这样的：使用iTunes文件共享.

要启用 iTunes 文件共享，请在 info.plist 中将键 UIFileSharingEnabled 设置为 true。

然后当用户将设备连接到 iTunes 并在 iTunes 中查看已安装的应用程序时，您的应用程序将列在 "file sharing" 个应用程序中，并且存储在应用程序的 Documents 目录中的文件将可供用户保存。
