Question

我使用iCloudDocumentSync库在iCloud（iCloud Container）中存储/检索文件。我有NSArray对象，我将此数组转换为NSData：

NSKeyedArchiver.archivedDataWithRootObject(foundationArray)

并将文件存储到iCloud。一切正常。

当我检索到这个文件，并尝试将NSData转换为NSArray时，我有错误：

iCloud.sharedCloud().retrieveCloudDocumentWithName(backupName, completion: { (document, data, error) -> Void in

                if error == nil {
                    print(document.fileURL)
//                    let addressBook = NSKeyedUnarchiver.unarchiveObjectWithFile(document.fileURL.URLString)
                    let addressBook = NSKeyedUnarchiver.unarchiveObjectWithData(data)
                    print(addressBook)
                    progressHUD.hide(true)
                }
            })

Eror：

你必须将你的网址转换为NSURL，你要传递给接受NSURL的参数类型。

let UrlToUse = NSURL(string: url)
