HTTP請求API調用

Question

我在IOS SDK下面的代碼我建：

+ (void) makeRequestToEndPoint:(NSString *) endpoint values:(NSMutableDictionary *) params onCompletion:(SDKCompletionBlock) responseHandler 
{ 
    [params setObject: key forKey: @"key"]; 

    NSString * urlString = [self createApiUrlFromEndpoint: endpoint]; 
    NSURL * url = [NSURL URLWithString: urlString]; 

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: url]; 
    request.HTTPMethod = @"POST"; 
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
    [request setValue:@"charset" forHTTPHeaderField:@"utf-8"]; 
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
    request.HTTPBody = [[params urlEncodedString] dataUsingEncoding:NSUTF8StringEncoding]; 

    [NSURLConnection sendAsynchronousRequest:request 
             queue:[NSOperationQueue mainQueue] 
          completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) 
    { 

     NSError * dicError = nil; 
     NSDictionary * dictionary = nil; 

     if([data length] >= 1) { 
      dictionary = [NSJSONSerialization JSONObjectWithData: data options:kNilOptions error: &dicError]; 
     } 

     responseHandler(dictionary, error); 
    }]; 

} 

因此，使用SDK的人可以通過執行以下API調用：

[SDK makeRequestToEndpoint ：@]

上面的代碼的結構（處理錯誤處理，響應處理等的最佳方式）的最佳方式是什麼，以方便人們使用SDK？
