func twitterSender(photoImported: UIImage) ->Void {

    let accountType = account.accountTypeWithAccountTypeIdentifier(
        ACAccountTypeIdentifierTwitter)

    account.requestAccessToAccountsWithType(accountType, options: nil,
        completion: {(success: Bool, error: NSError!) -> Void in

            if success {
                let arrayOfAccounts =
                account.accountsWithAccountType(accountType)

                if arrayOfAccounts.count > 0 {

                    let imageString = imageData.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.allZeros)
                    message["media_ids"] = imageString
                    let requestURL = NSURL(string:
                        "https://api.twitter.com/1.1/statuses/update.json")
                    let postRequest = SLRequest(forServiceType:
                        SLServiceTypeTwitter,
                        requestMethod: SLRequestMethod.POST,
                        URL: requestURL,
                        parameters: message)

                    postRequest.addMultipartData(imageData, withName: "oauth_*", type: "application/octet-stream", filename: "image.jpg")
                    postRequest.account = twitterAccount

                    postRequest.performRequestWithHandler({
                        (responseData: NSData!,
                        urlResponse: NSHTTPURLResponse!,
                        error: NSError!) -> Void in

                        if let err = error {
                            println("Error : \(err.localizedDescription)")
                        }
                        println("Twitter HTTP response \(urlResponse.statusCode)")
                    })
                }
            }
    })

}

我的代码的问题是只能发布没有图像的文本。我搜索了很多，并尝试在 twitter 的网站上找到一些信息。但我仍然很困惑如何去做。Twitter 曾经有一个名为 POST statuses/update_with_media 的 API 来完成我现在想做的工作。不幸的是，twitter 放弃了那个 API 并使用了一个新的。所以我确实发现了一些与我类似的问题，但所有这些问题要么使用objective-c，要么使用旧的twitter API。没有什么对我有帮助。由于大量研究花费了我很多时间，看起来我需要使用 addMultipartData 来完成这项工作，但我不知道如何填充这些参数，或者这可能是一个错误的方向。

您需要使用 update.json 并使用带有 NSData 的 addMultipartData 提供图像。这对我有用：

func tweetWithImage(data:NSData)
{

    let account = ACAccountStore()
    let accountType = account.accountTypeWithAccountTypeIdentifier(
        ACAccountTypeIdentifierTwitter)

    account.requestAccessToAccountsWithType(accountType, options: nil,
        completion: {(success: Bool, error: NSError!) -> Void in
            if success {
                let arrayOfAccounts =
                account.accountsWithAccountType(accountType)

                if arrayOfAccounts.count > 0 {
                    let twitterAccount = arrayOfAccounts.first as! ACAccount
                    var message = Dictionary<String, AnyObject>()
                    message["status"] = "Test Tweet with image"

                    let requestURL = NSURL(string:
                        "https://api.twitter.com/1.1/statuses/update.json")
                    let postRequest = SLRequest(forServiceType:
                        SLServiceTypeTwitter,
                        requestMethod: SLRequestMethod.POST,
                        URL: requestURL,
                        parameters: message)

                    postRequest.account = twitterAccount
                    postRequest.addMultipartData(data, withName: "media", type: nil, filename: nil)

                    postRequest.performRequestWithHandler({
                        (responseData: NSData!,
                        urlResponse: NSHTTPURLResponse!,
                        error: NSError!) -> Void in
                        if let err = error {
                            println("Error : \(err.localizedDescription)")
                        }
                        println("Twitter HTTP response \(urlResponse.statusCode)")

                    })
                }
            }
            else
            {
                // do what you want here

            }
    })
}

我在我的博客上放了一个教程，并在 GitHub 中展示了使用 SLRequest 以便支持动画 GIF 的相应项目......你可以在这里看到它：http: //www.iosinsight.com/twitter-integration-with-迅速/

注意：此代码和博客文章是根据 maml 关于使用简单的“更新”而不是弃用的“update_with_media”的评论更新的。
