Methods like - mapView: didUpdateUserLocation:
are never called.
This happens because when you first set the delegate to a MKMapView, it asks you a series of respondToSelector: with all the delegate methods in order to create its own delegate flags (like you do with the struct _flags
).
In your code this happens in the - commonInitialization
this method is called by - initWithCoder
or - initWithFrame
, and therefor I haven't the opportunity to set my delegate before this method has been called.
What happens next is that MKMapView implementation start asking your the series of respondToSelector
but when the following code is called:
- (BOOL)respondsToSelector:(SEL)aSelector
{
if (![super respondsToSelector:aSelector])
{
return [_targetDelegate respondsToSelector:aSelector];
}
return YES;
}
_targetDelegate
is nil and returns NO.
This cause the fact that mapView never call again delegate methods.
