Question

我正在使用OCMock模拟NSURLConnection / NSURLResponse（是的，我确实知道它们已被弃用），并且一切正常，因为我希望它模拟http响应代码和http正文。现在，我正在尝试扩展它并模拟http头字段，但是我遇到了编译错误，并且不明白为什么。这是一些代码：

id   gNSHTTPURLResponseMock = [OCMockObject niceMockForClass:[NSHTTPURLResponse class]];

...

    [[[gNSHTTPURLResponseMock stub] andReturnValue:OCMOCK_VALUE(statusCode)] statusCode];
     if (header)
     {
         [[[gNSHTTPURLResponseMock stub] andReturnValue:OCMOCK_ANY(allHeaderFields)] header];
     }
     [gNidHTTPConnectionObject connection:gDummyUrlConnection didReceiveResponse:gNSHTTPURLResponseMock];

我得到的错误是它说：使用未声明的标识符“ allHeaderFields”。但是，这里是NSHTTPURLResponse的定义，可以看到我正在嘲弄的状态以及我正在得到错误的allHeaderFields。由于定义了allHeaderFields，所以我不明白为什么会出现此编译错误（如果我使用OCMOCK_VALUE而不是OCMOCK_ANY，则会出现相同的错误）

@interface NSHTTPURLResponse : NSURLResponse 
{
    @package
    NSHTTPURLResponseInternal *_httpInternal;
}

/*!
  @method   initWithURL:statusCode:HTTPVersion:headerFields:
  @abstract initializer for NSHTTPURLResponse objects.
  @param    url the URL from which the response was generated.
  @param    statusCode an HTTP status code.
  @param    HTTPVersion The version of the HTTP response as represented by the server.  This is typically represented as "HTTP/1.1".
  @param    headerFields A dictionary representing the header keys and values of the server response.
  @result   the instance of the object, or NULL if an error occurred during initialization.

我通过执行以下操作使它起作用：

//Array with date values in order(last 30 Days)

  for (var i = 0; i < 30; i++) {
        date = this.substractDays(date, 1);
        arrayDate.push(date);
    }

    console.log(arrayDate);

    arrayDate.forEach((item, index) => {
        month = item.getMonth();
        month++;

        newFormatDate = item.getFullYear() + "-" + month + "-" + item.getDate();
//get date for each days
        this.subscription = this.dataService.APICall(newFormatDate).subscribe(data => {
            this.Results.push({ "date": item, "data": data.count });

 });
console.log(Results);

不知道为什么其他方式对statusCode有效，但对allHeaderFields不起作用，但是以上方法对allHeaderFields有效。

我可以模拟NSHTTPURLResponse的状态，但不能模拟其allHeaderFields
