Dropbox usersGetCurrentAccount 无成员编译器错误

Question

使用IOS 9.1，运行在Xcode 7.1.1上。在埃尔卡皮坦之下。我正在尝试通过他们的（可能是新的）SwiftDropbox 库访问 Dropbox 的教程，请按照此页面进行操作。

https://blogs.dropbox.com/developers/2015/05/try-out-swiftydropbox-the-new-swift-sdk-for-dropbox-api-v2/

开始顺利，设法连接并获得授权，但无法做更多事情，因为发布到他们的教程的代码无法编译。

if let client = Dropbox.authorizedClient {
 
    // Get the current user's account info
    client.usersGetCurrentAccount().response { response, error in
        if let account = response {
            println("Hello \(account.name.givenName)")
        } else {
            println(error!)
        }
    }
     
    // List folder
    client.filesListFolder(path: "").response { response, error in
        if let result = response {
            println("Folder contents:")
            for entry in result.entries {
                println(entry.name)
            }
        } else {
            println(error!)
        }
    }

抱怨

DropboxClient

没有成员“usersGetCurrentAccount”或“filesListFolder”，我认为它们是某种排序方法调用{对于 swift 来说也是相当新的}。谷歌似乎找不到任何有用的线索？这段代码应该读/说什么？

邦，

谢谢你，smarx；你让我走上了正确的道路。这是最终的代码；对他在这里提到的教程进行了两个小修正。

//  ViewController.swift

import UIKit
import SwiftyDropbox

class ViewController: UIViewController {


@IBAction func linkButtonPressed(sender: AnyObject) {
        if (Dropbox.authorizedClient == nil) {
            Dropbox.authorizeFromController(self)
        } else {
            print("User is already authorized!")
        }
}


override func viewDidLoad() {
    super.viewDidLoad()

    // Verify user is logged into Dropbox
    if let client = Dropbox.authorizedClient {

        // Get the current user's account info
        client.users.getCurrentAccount().response { response, error in
            print("*** Get current account ***")
            if let account = response {
                print("Hello \(account.name.givenName)!")
            } else {

            }
        }

您正在阅读 5 月份发布的有关 SDK 早期预览版的博客文章。自那篇文章以来，很多事情都发生了变化！查看 https://www.dropbox.com/developers/documentation/swift#tutorial 获取最新教程。

我相信你想要

users.getCurrentAccount

和

files.listFolder

。
