MKMapkit constraint error when reopen project

Question

I built a custom view controller. It has 1 tableview, 2 views and 1 map. When I set the constraints for this layout it works fine. I close project and reopen the map view out of the view controller. The width and height are 1000 points. If I set the map on top of this stack, there is no problem. But when I set map in the middle of the other views, a problem happens. I must put this mapview inside another view or it affects the others, but the problem is still there.

I use Xcode 8 beta 5, and constraint is 0 0 0 0

Answer 1

I have the same issue in the latest beta. I believe the problem is in the wrong default size, that is always set to 1000x1000 by Xcode for MKMapView.

I would wait for the fix in the next Xcode version.

If you, by some reason, really need it fixed now, you can setup a UIView with constraints as required, then put MKMapView inside the UIView and use Autoresizing to scale it.
