A Few Questions About MapKit

1. Is it possible to contain an MKMapView within certain coordinates? perhaps by programatically shifting (bounce back) the view when a boundary is reached?

2. For offline support, is it possible to save/refer to an MKMapView within certain coordinates?

 

sorry, my second question was more referencing the ability to actually view the map when offline. if i turn off wifi on my iPod touch the map isn't saved, and doesn't reload - i get grid lines only. is there a way to force-cache, or save a map (EX: the city of Montréal, from 4 corner coordinates or something like that) for viewing offline?

[EDIT]

oh... and one more question to add to my list:

3. i've set the image property of the MKAnnotationView to replace the default pin annotations with my own image. however, canShowCallout is also set to yes, and while the map loads with my custom annotations, whenever i tap to show a callout, the image of the annotation i've tapped changes into a pin. i haven't yet tried to actually subclass MKPinAnnotationView, and currently believe that is why this is happening, but if that's the case, what's the purpose of the image property?

Code:

MKAnnotationView *annotationView = [self.myMapView dequeueReusableAnnotationViewWithIdentifier:@"AnnotationID"];

if (annotationView == nil)
	{
	annotationView = [[[MKPinAnnotationView alloc] initWithAnnotation:annot reuseIdentifier:@"AnnotationID"] autorelease];
	annotationView.image = [UIImage imageNamed:@"customPin.png"];
	annotationView.canShowCallout = YES;
	}

return annotationView;

[EDIT Again] ah, the image property only works in the subclass... clearly...
