Question

func twitterSender(photoImported: UIImage) ->Void {
    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.last as! ACAccount
                    var message = Dictionary<String, AnyObject>()
                    message["status"] = "My app test 5"
                    let imageData = UIImageJPEGRepresentation(photoImported, 0.9)
                    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做到这一点。 Twitter曾经有一个名为POST status / update_with_media的API来完成我现在想做的工作。不幸的是，twitter丢弃了该API并使用了新API。所以我确实在我的网站上找到了一些类似的问题，但他们都使用了objective-c或者使用了旧的twitter API。没有什么对我有帮助。有很多研究耗费了我很多时间，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，或者这也许是一个错误的方向。

func twitter(){
    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.last as! ACAccount
        var message = Dictionary<String, AnyObject>()
        message["status"] = self.txtPostDesc.text! //textbox
        let imageData = UIImagePNGRepresentation(self.imagePost)//pickerview add
        let imageString = imageData!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions())
        message["media_ids"] = imageString
        let requestURL = NSURL(string: "https://upload.twitter.com/1/statuses/update_with_media.json")
        let postRequest = SLRequest(forServiceType: SLServiceTypeTwitter, requestMethod: SLRequestMethod.POST, URL: requestURL, parameters: message)

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

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

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

            }
        }
    })

}

您需要使用update.json并使用NSData为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

            }
    })
}

我已经在我的博客上添加了一个教程，其中包含GitHub中的相应项目，该项目说明了使用SLRequest以便支持动画GIF ...您可以在此处看到它：http://www.iosinsight.com/twitter-integration-with-swift/

注意：此代码和博客帖子根据maml关于使用简单＆＃34;更新＆＃34;的评论进行更新。而不是弃用＆＃34; update_with_media＆＃34;。

如何使用swift上的SLRequest类将图像和文本发布到twitter？
