Xamarin.Forms.Maps iOS填充

Question

I am having trouble finding a solution for my problem. I am looking to set the padding for the Xamarin Forms Map (Mapkit/MKMapView) on iOS (Custom Renderer).

For Android it can be set in the custom renderer with NativeMap.SetPadding(10,200,10,10) but I cannot find a way to do it in iOS.

The problem I am trying to solve is that the compass on the map appears on the top right corner of the map (iOS) and since I do have my own controls on the top of the map, the compass is not accessible.

On android setting the padding pushes the compass down below my controls and solves the issue.

I'd appreciate any suggestion on how to solve it for iOS

MapKit.MKMapView

You can create your own MKCompassButton and alter its X/Y position (via its Frame) on the map.

var compass = MKCompassButton.FromMapView(mkMapViewInstance);
compass.CompassVisibility = MKFeatureVisibility.Visible;
compass.Frame = new CGRect( new CGPoint(25,25), compass.Frame.Size);

Google.Maps.MapView (iOS)

You can add padding around the edges of the map using the GMSMapView.padding property. The map will continue to fill the entire container, but text and control positioning, map gestures, and camera movements will behave as if it has been placed in a smaller space. This results in the following changes:

myGMSMapViewInstace.Padding = new UIEdgeInsets(100.0f, 100.0f, 100.0f, 100.0f);
