Specify if current thread is main thread or not

Question

Is there any way to specify if current thread is main thread or not in objective-c?

I want to do something like this.

  - (void)someMethod
  {
    if (IS_THIS_MAIN_THREAD?) {
      NSLog(@"ok. this is main thread.");
    } else {
      NSLog(@"don't call this method from other thread!");
    }
  }

Have a look at NSTHread API documentation at this page. There are methods like - (BOOL)isMainThread + (BOOL)isMainThread and + (NSThread *)mainThread
