在swift

Question

我正在使用TwitterKit，我需要使用图片或视频以及描述发布状态。麻烦的是它没有给我任何类型的错误代码，所以我不知道它为什么不工作。这是我到目前为止的代码：

编辑：好的，我现在收到一个错误。错误是

Error uploading image Optional(Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo=0x14604e90 {NSErrorFailingURLStringKey=https://upload.twitter.com/1.1/media/upload.json, NSErrorFailingURLKey=https://upload.twitter.com/1.1/media/upload.json, NSLocalizedDescription=The request timed out., NSUnderlyingError=0x14611520 "The request timed out."})

编辑2：确定以下所有代码都正常工作，除非我尝试上传视频时发回400错误错误请求

所以一切都是一样的，除了我改变了代码的媒体行：

var imageData : NSData = UIImageJPEGRepresentation(self.image!, 0.5)
                parameters["media"] = imageData.base64EncodedStringWithOptions(nil)

到这个

parameters["media"] = self.video!.base64EncodedStringWithOptions(nil) //self.video is NSData

这是代码：

 Twitter.sharedInstance().logInWithCompletion {
                    (session, error) -> Void in
                    if session != nil {
                        println("signed in as \(session.userName)")
                        let strUploadUrl = "https://upload.twitter.com/1.1/media/upload.json"
                        let strStatusUrl = "https://api.twitter.com/1.1/statuses/update.json"
                        UIApplication.sharedApplication().networkActivityIndicatorVisible = true
                        var twAPIClient = Twitter.sharedInstance().APIClient
                        var error: NSError?
                        var parameters:Dictionary = Dictionary<String, String>()
                        // get image from bundle
                        var imageData : NSData = UIImagePNGRepresentation(self.image!)

                        parameters["media"] = imageData.base64EncodedStringWithOptions(nil)
    //for uploading video would I just do this parameters["media'] = NSData.dataWithContentsOfMappedFile(url.relativePath!) as? NSData
                        var twUploadRequest = twAPIClient.URLRequestWithMethod("POST", URL: strUploadUrl, parameters: parameters, error: &error)
                        if true {
                            twAPIClient.sendTwitterRequest(twUploadRequest) {
                                (uploadResponse, uploadResultData, uploadConnectionError) -> Void in
                                if (uploadConnectionError == nil) {
                                    // using SwiftyJSON to parse result
                                    let json = JSON(data: uploadResultData!)
                                    // check for media id in result
                                    if (json["media_id_string"].string != nil) {
                                        println("result = \(json)")
                                        // post a status with link to media

                                            twAPIClient.sendTwitterRequest(twStatusRequest) { (statusResponse, statusData, statusConnectionError) -> Void in
                                                if (statusConnectionError != nil) {

最新的Twitter API使得在Twitter上发布带有图像和消息的推文非常容易。根据您上面的示例，下面是一个适合我的示例代码。如果您遇到任何问题，请验证并告知我们。更多细节 - ＆gt; Twitter API's github page

TWTRTwitter.sharedInstance().logInWithCompletion {
                (session, error) -> Void in
                if session != nil {
                    println("signed in as \(session.userName)")

                    let twitterUserID = TWTRTwitter.sharedInstance().sessionStore.session()?.userIDUIApplication.sharedApplication().networkActivityIndicatorVisible = true
                    var twAPIClient = TWTRAPIClient(userID: twitterUserID)
                    twitterAPIclient.sendTweet(withText: "Hey look at this", image: self.image!, completion: {(tweet, error) in

        if tweet?.createdAt != nil {
            print("Tweet posted: \(tweet.debugDescription)")
        }
        if error?.localizedDescription != nil {
            print("error posting Tweet: \(error?.localizedDescription ?? "default error message")")
        }
    })     UIApplication.sharedApplication().networkActivityIndicatorVisible = false
                }
            }
