在成功进行应用内购买后，我一直在尝试访问下载的SKDownloadzip 文件：

func paymentQueue(_ queue: SKPaymentQueue, updatedDownloads downloads: [SKDownload]) {
  downloads.forEach ({ (download) -> Void in
     switch download.state {
        ...
        case .finished:
           self.processDownload(download: download)
           ...
           break

        ...
    })
}

这是处理下载SKDownload文件的函数：

func procesessDownload(download: SKDownload) {
    guard let hostedContentPath = download.contentURL else {
        return
    }

    do {
        // THIS LINE OF CODE THROWS WITH THE ERROR POSTED BELOW
        let files = try FileManager.default.contentsOfDirectory(atPath: hostedContentPath.relativePath)

    } catch {
        //catch error
    }
}

当我检查download.contentURL它时：

file:///private/var/mobile/Containers/Data/Application/D755EC3C-2BA6-43A8-BB21-938B38EBFCB7/Library/Caches/EB11461D-71C8-42C7-9C99-E6F8B81161EE.zip/
  - _url : file:///private/var/mobile/Containers/Data/Application/D755EC3C-2BA6-43A8-BB21-938B38EBFCB7/Library/Caches/EB11461D-71C8-42C7-9C99-E6F8B81161EE.zip/

但是在尝试FileManager使用上面的这行代码访问文件时：

let files = try FileManager.default.contentsOfDirectory(atPath: hostedContentPath.relativePath)

我不断收到以下错误消息，指出该文件不存在：

Error Domain=NSCocoaErrorDomain Code=260 "The file “EB11461D-71C8-42C7-9C99-E6F8B81161EE.zip” couldn’t be opened because there is no such file." UserInfo={NSFilePath=/private/var/mobile/Containers/Data/Application/D755EC3C-2BA6-43A8-BB21-938B38EBFCB7/Library/Caches/EB11461D-71C8-42C7-9C99-E6F8B81161EE.zip, NSUnderlyingError=0x28320d500 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}

  • 我尝试/在最后添加以将 zip 文件视为目录和许多其他内容均无济于事。

  • 我什至尝试访问包含该文件的目录（直到 zip 文件）：

/private/var/mobile/Containers/Data/Application/D755EC3C-2BA6-43A8-BB21-938B38EBFCB7/Library/Caches/

错误说找不到“缓存”目录。

  • 我还尝试"Contents"像随机人找到的示例代码之一一样添加到路径中。

我已经连续敲了一天多的头，但找不到任何关于此事的文件。任何帮助将不胜感激，谢谢！
