Mapview not able to scroll on Iphone os3.2 and 4

Question

HI I have a main view on which i added a view and then I added a mapview. This mapview is perfectly scrolling in iPhone SDK3.1.3 but i am not able to scroll it on iPhone SDK3.2 and 4.0. Can anyone help me. actully on middle view we write some tuoch event to trap the touch of user.

code is this viewTouch = [[UIViewTouch alloc] initWithFrame:CGRectMake(0, 0, 320, 430)] [self.view addSubview:viewTouch]; [viewTouch addSubview:my_mapView];

Thanks in advance.
