Question

当我第一次在Twitter Api上玩时，我在使用NSMutableURLRequest为update_with_media twitter构建主体时遇到了问题。在这里我不使用MGTwitterEngine。

注册，updated_status等工作正常。

NSString *postUrl = @"https://api.twitter.com/1/statuses/update_with_media.json";

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:postUrl]];

    NSString *iString =@"hi test url";

   // NSData *imageData = UIImagePNGRepresentation(iImage);

//    NSMutableDictionary *postInfo = [NSMutableDictionary
//                                     dictionaryWithObject:iString
//                                     forKey:@"status"];

    NSMutableDictionary *postInfo = [NSMutableDictionary dictionaryWithObjectsAndKeys:iImageData,@"media[]",iString,@"status",nil];

    NSString *postBodyString = [NSString stringWithFormat:@"status=%@", [iString encodedURLParameterString]];

    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:[postBodyString dataUsingEncoding:NSUTF8StringEncoding]];
    [request setValue:[self oAuthHeaderForMethod:@"POST"
                                          andUrl:postUrl
                                       andParams:postInfo] forHTTPHeaderField:@"Authorization"];

    NSHTTPURLResponse *response;
    NSError *error = nil;

    [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

    if (error)
    {
        //        NSLog(@"Error from NSURLConnection: %@", error);

    }
    NSLog(@"Status posted. HTTP result code: %d", [response statusCode]);

我尝试发送请求我收到此错误
