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似乎唯一的API提供的是，如果上传完成或失败，他们可能是-------他们没有提供知道它的方法吗？

我也没有找到关于这个主题的任何问题，我不可能是唯一对此感兴趣的人，如果有人知道其他任何事情，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];
        }
    }
}];

}

使用preparedURLRequest获取NSURLRequest对象。使用NSURLConnection手动发送请求可让您提供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我是如何处理AFNetworking的，在拥有SLRequest对象后，我使用@Jesper方式来获得进度监听器。

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];

希望有所帮助！
