我正在使用 iOS6 的新社交 API 实现 Facebook 视频上传，一切正常，除了我没有找到知道上传进度的方法……Apple 似乎提供的唯一 API 是如果上传完成或失败，有可能他们是如此--------以至于他们没有提供知道它的方法吗？

我也没有找到关于这个话题的任何问题，不可能只有我对此感兴趣，如果有人知道其他任何事情，请告诉我们。

谢谢 ！

我一直在努力解决这个问题，终于让它工作了。我想我会分享我的片段：

-(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];
        }
    }
}];

}

用于preparedURLRequest获取NSURLRequest对象。通过手动发送请求，NSURLConnection您可以提供一个可以处理委托方法的委托，例如connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite:.

对于那些感兴趣的人来说，我是如何使用 AFNetworking 的，在拥有一个 SLRequest 对象之后，我使用@Jesper 的方式来获取一个进度监听器。

NSURLRequest* preparedRequest = [uploadRequest preparedURLRequest];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:preparedRequest];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
    NSLog(@"%lld bytes out of %d sent.", totalBytesWritten, fileSize);
    float progress = totalBytesWritten/(float)fileSize;
}];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Facebook upload success");
    });
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Facebook upload error");
    });
}];

[operation start];

希望有帮助！
