Objective Flickr - 从NSMutablearray错误在Flickr上发布多张照片

Question

我正在创建一个应用程序，让用户可以发布到他们的Flickr照片流。我正在使用ObjectiveFlickr来处理授权和发布过程。

对于发布单张图片，我使用以下代码：

if (isSinglePic) {
            UIImage *img = self.singlePic;
            NSData *JPEGData = UIImageJPEGRepresentation(img, 1.0);

            self.flickrRequest.sessionInfo = __kUploadImageStep;
            [self.flickrRequest uploadImageStream:[NSInputStream inputStreamWithData:JPEGData] suggestedFilename:self.descriptionTextField.text MIMEType:@"image/jpeg" arguments:[NSDictionary dictionaryWithObjectsAndKeys:@"0", @"is_public", nil]];

            //[NSDictionary dictionaryWithObjectsAndKeys:photoID, @"photo_id", @"PicknPost", @"title", @"via PicknPost", @"description", nil]]

            [UIApplication sharedApplication].idleTimerDisabled = YES;
        }

这很好用。但是，当我尝试发布存储在NSMutableArray中的多个图片时，ObjectiveFlickr仅上传第一张图片。

我发布多张照片的代码如下所示：

NSMutableArray *array = [[NSMutableArray alloc] initWithArray:picsToPost copyItems:YES];


            for (UIImage *imgToPost in array) {
                NSData *JPEGData = UIImageJPEGRepresentation(imgToPost, 1.0);

                self.flickrRequest.sessionInfo = __kUploadImageStep;
                [self.flickrRequest uploadImageStream:[NSInputStream inputStreamWithData:JPEGData] suggestedFilename:self.descriptionTextField.text MIMEType:@"image/jpeg" arguments:[NSDictionary dictionaryWithObjectsAndKeys:@"0", @"is_public", nil]];

                [UIApplication sharedApplication].idleTimerDisabled = YES;

有没有人知道为什么for-in语句不起作用？

任何帮助都将不胜感激。
