Convert MKMapRect to CGRect
mapkit, mkmaprect, objective-c
Solution
The map view has the `convertRegion:toRectToView:` method which takes an `MKCoordinateRegion` and converts it to a `CGRect` relative to the specified view.
If you have an `MKMapRect`, first convert it to an `MKCoordinateRegion` using the `MKCoordinateRegionForMapRect` function and then call `convertRegion:toRectToView:`.
Example:
MKCoordinateRegion mkcr = MKCoordinateRegionForMapRect(someMKMapRect);
CGRect cgr = [mapView convertRegion:mkcr toRectToView:self.view];
Remember that although the `MKMapRect` for some fixed area will not change as the map is zoomed or panned, the corresponding `CGRect` will vary in its `origin` and `size`.
Problem
I'm trying to find out the size of an MKMapRect in points (i.e. 320x568 points for iPhone). Is there something similar to converting co-ordinates to points? i.e. ``` [self.mapView convertCoordinate:coordinate1 toPointToView:self.view]; ```
