在 iPhone 模拟器中很难通过 MFMessageComposeViewController 获得 SMS 功能

我是 iPhone 开发新手。

这是我的问题。我想在将 iPhone 模拟器部署到手机之前对其进行“设备短信功能”检查。这是我在 .m 文件中编写的代码。这是触发我的短信按钮时调用的函数。

    Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));
 if (messageClass != nil)
 {
   NSLog (@" \ntxting\n");
  // We must always check whether the current device is configured for sending messages
  if ([messageClass canSendText] == TRUE)
  {
   NSLog (@"canSendText is not passingg"); //Not entering this loop
   [self displayTextSheet];
  }

问题是if循环没有进入。我想知道 Messageview 控制器是否根本不会在模拟器中弹出，并且仅适用于手机。

请指教。

更新：我在 messageClass if 循环中添加了一个 NSLog 并打印出来。所以 messageClass 不是“nil”

I am new to iPhone developement.

Here is my question.
I would like to do a 'device texting capability' check on my iPhone simulator before I deploy it to my phone. This is the code I wrote in the .m file.
This is the function which is called when my SMS button is triggered.

    Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));
 if (messageClass != nil)
 {
   NSLog (@" \ntxting\n");
  // We must always check whether the current device is configured for sending messages
  if ([messageClass canSendText] == TRUE)
  {
   NSLog (@"canSendText is not passingg"); //Not entering this loop
   [self displayTextSheet];
  }

The problem is that the if-loop does not enter.
I was wondering if the Messageview controller does not pop up in the simulator at all and only for the phone.

Please advice.

Update: I have added a NSLog in the messageClass if loop and that gets printed.
so messageClass is not 'nil'
