Hi MilkyJoe,
The following code *might* be faster, depending on what the compiler does:
NSOobject[] annotations = map.Annotations;
foreach (NSObject annotation in annotations) {
if (!(annotation is MKUserLocation)) {
mvMap.RemoveAnnotation (annotation);
}
}
You could also try collecting an array/list of MKAnnotations and then call
map.RemoveAnnotations (array) - that may be slightly faster, but you'd have
to check to see.
Hope that helps,
Jeff
