SLRequest进度回调(iOS 6)

Question

我正在使用适用于iOS6的新社交API实现Facebook视频上传,一切正常,但我没有找到方法来了解上传的进展情况...... Apple似乎提供的唯一API就是如果上传完成或失败,那么他们可能是-------他们没有提供方法来知道它？

我也没有找到关于这个话题的任何问题,我不可能是唯一对它感兴趣的人,如果有人知道其他事情,请告诉我们.

谢谢 !

我正在努力解决这个问题,最终让它发挥作用.我以为我会分享我的片段:

-(void)sendTwitter {
ACAccountStore *account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:
                              ACAccountTypeIdentifierTwitter];

[account requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error) {
    if (granted == YES) {
        NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
        if ([arrayOfAccounts count] > 0) {
            twitterAccount = [arrayOfAccounts lastObject];

            NSString *status = @"Secrets";
            UIImageView *uploadImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 640, 480)];
            UIImage *uploadImage = [image resizedImageToFitInSize:uploadImageView.bounds.size scaleIfSmaller:NO];

            NSURL *requestURL = [NSURL URLWithString:@"https://upload.twitter.com/1.1/statuses/update_with_media.json"];

            SLRequest *postRequest = [SLRequest
                                      requestForServiceType:SLServiceTypeTwitter
                                      requestMethod:SLRequestMethodPOST
                                      URL:requestURL parameters:nil];
            [postRequest addMultipartData:UIImageJPEGRepresentation(uploadImage, 0.6) withName:@"media[]" type:@"multipart/form-data" filename:nil];
            [postRequest addMultipartData:[status dataUsingEncoding:NSUTF8StringEncoding] withName:@"status" type:@"multipart/form-data" filename:nil];
            [postRequest setAccount:twitterAccount];

            NSURLRequest *preparedRequest = [postRequest preparedURLRequest];

            AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:preparedRequest];

            [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
                NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite);
            }];
            [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
                    NSLog(@"Twitter upload success");
                    [self completedSendingPhotos];
                } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                    NSLog(@"Twitter upload error");
                }];

            [operation start];
        }
    }
}];

}
