Error CS1061 'CustomPin' does not contain a definition for 'AddAnnotation' and no accessible extension method 'AddAnnotation' accepting a first argument of type 'CustomPin' could be found (are you missing a using directive or an assembly reference?)

The repro project:

The mentioned class is here: https://github.com/HobDev/CustomPinSample/blob/master/CustomizedMap/Platforms/iOS/MapExtensions.cs

But AddAnnotation() is method in MapExtensions class. How it can be called by control.AddAnnotation() as control is type of CustomPin.

VladislavAntonyuk commented

the problem is in your namespace. you should either add

#if IOS
using CustomizedMap.Platforms.iOS
#endif

or change the namespace to CustomizedMap.CustomControl

HobDev commented

@VladislavAntonyuk Thank you ! the issue is resolved by adding the namespace in iOS if directive. But I am still getting default pins on iOS

VladislavAntonyuk commented

Is the code in AddAnnotation executed?

HobDev commented

You directed me to the right code to debug. The AddAnnotation was executed but Map in the following code was null:
var nativeMap = (MauiMKMapView)pin.Map?.Handler?.PlatformView;
After setting the Map value in the ItemTemplate of the Map the code worked.
