Question

I am trying to implement the method below to select the set of annotations in the visible region of my map.

- (NSSet *)annotationsInMapRect:(MKMapRect)mapRect

I added the line in my code as such

NSSet *nearbySet = [self annotationsInMapRect:self.mapView.frame];

My app is crashing because of this. Can anyone advise on how I should use the above method correctly?

EDIT:
Stack Trace is as follows:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CarParkTableViewController annotationsInMapRect:]: unrecognized selector sent to instance 0x187b60'

Thanks

Try

NSSet *nearbySet = [self.mapView annotationsInMapRect:self.mapView.frame];

Your posted error shows that self is not an instance of MKMapView but annotationsInMapRect is a message you can send only to that class.
