iOS-无法使用Twitter/Fabric新SDK上载媒体

我想从我的iOS应用程序向twitter发布一张照片。我可以在没有媒体的情况下发布推文，但当我尝试连接媒体时，它会抛出一个错误

我正在关注twitter文档，根据这一点，首先我需要将媒体上传到，然后我将能够使用media-id将其与tweet连接起来

这是我上传媒体的代码

应用程序在URLRequestWithMedthod调用时崩溃

帮我解决这个问题

UIImage *image = [UIImage imageNamed:@"shareit.png"];
NSData *imageData = UIImageJPEGRepresentation(image, 0.7);
NSString *statusesShowEndpoint = @"https://upload.twitter.com/1.1/media/upload.json";
NSDictionary *params = @{@"media" : imageData};
NSError *clientError;
NSURLRequest *request = [[[Twitter sharedInstance] APIClient] 
                         URLRequestWithMethod:@"POST"
                         URL:statusesShowEndpoint
                         parameters:params
                         error:&clientError];

if (request) {
    [[[Twitter sharedInstance] APIClient]
     sendTwitterRequest:request
     completion:^(NSURLResponse *response,
                  NSData *data,
                  NSError *connectionError) {
         if (data) {
             // handle the response data e.g.
             NSError *jsonError;
             NSDictionary *json = [NSJSONSerialization
                                   JSONObjectWithData:data
                                   options:0
                                   error:&jsonError];
             NSLog(@"%@",json);
         }
         else {
             NSLog(@"Error: %@", connectionError);
         }
     }];
}
else {
    NSLog(@"Error: %@", clientError);
}

其实很简单。缺少的只是将imagedata转换为base64EncodedString。这是解决办法

   NSString *media = @"https://upload.twitter.com/1.1/media/upload.json";

   NSData *imageData = UIImageJPEGRepresentation(image, 0.9);

   NSString *imageString = [imageData base64EncodedStringWithOptions:0];
   NSError *error;
   NSURLRequest *request = [[[Twitter sharedInstance] APIClient] URLRequestWithMethod:@"POST" URL:media parameters:@{@"media":imageString} error:&error];

   [[[Twitter sharedInstance] APIClient] sendTwitterRequest:request completion:^(NSURLResponse *urlResponse, NSData *data, NSError *connectionError) {

       NSError *jsonError;
       NSDictionary *json = [NSJSONSerialization
                              JSONObjectWithData:data
                              options:0
                              error:&jsonError];
       NSLog(@"Media ID :  %@",[json objectForKey:@"media_id_string"]);

      // Post tweet With media_id
    }];

完成萨尼的答案

// Post tweet With media_id

mediaID = [json objectForKey:@"media_id_string"];
client = [[Twitter sharedInstance] APIClient];
message = @{@"status": title, @"wrap_links": @"true", @"media_ids": mediaID};

NSURLRequest *request = [client URLRequestWithMethod:@"POST" URL:@"https://api.twitter.com/1.1/statuses/update.json" parameters:message error:&error];

[client sendTwitterRequest:request completion:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {

    if (connectionError) {
        NSLog(@"error %@",[connectionError localizedDescription]);
    } else {
        NSError *jsonError;
        NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonError];
        NSLog(@"json Finish! %@",json);
    }
}];

如果有人仍在寻求帮助，请共享swift 2.2（Xcoe 7.3.2）代码

 let client = TWTRAPIClient.init(userID:<Twitter_User_Id_Here>)
let imgData =  UIImageJPEGRepresentation(UIImage(named:"Home")!, 0.7)
    client.uploadMedia(imgData!, contentType: "image/jpeg", completion: {(media_ids,error) in

        if error == nil{
            //prints the media_ids in String. 
      //Pass them into the params of status update params ["media_ids":<MEDIA_ID>]
            print(media_ids)
        }
        else{
            print(error?.localizedDescription)
        }
    })

let client=TWTRAPIClient.init（userID:）
设imgData=uiImageJPEG表示法（UIImage（名为：“Home”）！，0.7）
client.uploadMedia（imgData！，contentType:“image/jpeg”，完成：{（media_id，error）in
如果错误==nil{
//以字符串形式打印媒体标识。
//将它们传递到状态更新参数[“媒体ID”：
打印（媒体标识）
}
否则{
打印（错误？.localizedDescription）
}
})

发送状态更新

   let request = client.URLRequestWithMethod("POST", URL: "https://api.twitter.com/1.1/statuses/update.json", parameters: ["status":"Hello World","media_ids":<Media_Ids_Here>], error: nil)

    client.sendTwitterRequest(request, completion: {
        (response,data,error)in
        if error == nil {
            print(data)

        }
        else{
            print("Error")
        }
    })
}

let request=client.URLRequestWithMethod（“POST”，URL:”https://api.twitter.com/1.1/statuses/update.json，参数：[“状态”：“你好世界”，“媒体ID”：]，错误：无）
client.sendTwitterRequest（请求、完成：{
（响应、数据、错误）
如果错误==nil{
打印（数据）
}
否则{
打印（“错误”）
}
})
}

这真的对你有用吗？我正在尝试这个，但503服务不可用。没有oauth_*params，你是如何让它工作的？@sun没有oauth_*params，它将无法工作。你需要在使用前登录。为我工作，谢谢！如何处理多个图像？你能帮我做这个吗
