    NSURL *url = [NSURL URLWithString:@"https://xxx.s3-ap-northeast-1.amazonaws.com/"];
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
    NSData *imageData = UIImagePNGRepresentation([UIImage imageNamed:@"194-note-2.png"]);
    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                            @"xxxxx/videos/XXXXW",@"key",
                            @"XXXXXXXX",@"AWSAccessKeyId",
                            
                            @"XXXXXXXXXXXXXXXXXXXXXXXXXXXXX",@"policy",
                            @"XXXXXXXXXXXXXXXXXXXXXXXXX",@"signature",
                            
                            nil];
    
    
    NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/" parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
        [formData appendPartWithFileData:imageData name:@"file" fileName:@"194-note-2.png" mimeType:@"image/png"];
    }];
    
    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
        NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);
    }];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *theOperation, id responseObject) {
        NSLog(@"Success:%@,%@",operation.response.allHeaderFields, operation.responseString);
        
        
        
    } failure:^(AFHTTPRequestOperation *theOperation, NSError *error) {
        NSLog(@"Error:%@ ,%@,%@",error,operation.response.allHeaderFields,operation.responseString);
    }];
    [operation start];
    


}

in the setCompletionBlockWithSuccess and the failure is a better option use the object "theOperation" instead of operation. It may causes of leaks.

Nice code btw
