shake detection in iPhone which is presented as ModalViewController from appdelegete?

I got the answer after breaking head for a day!!! (maybe a piece of cake for others).

here goes the solution:

In the root view controller or view controller from where we present modal view controller we have to detect shake:

- (void) viewWillAppear:(BOOL)animated
{
    [self becomeFirstResponder];
    [super viewWillAppear:animated];
}
- (void) viewWillDisappear:(BOOL)animated
{
    //[self resignFirstResponder];
    /*dont resign first responder on view disappear */  
    [super viewWillDisappear:animated];
}
- (BOOL)canBecomeFirstResponder
{ 
       return YES;
}

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
   if ( event.subtype == UIEventSubtypeMotionShake )
    {
    // Put in code here to handle shake
     }

   if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )
      [super motionEnded:motion withEvent:event];
}

present the modal view normally... shake will be detected in modalview also... Its tested and working!! Thanks all :)
