Mapbox-gl-native: Issue MGLAnnotationView subclass and AutoLayout

[aodhol]

Platform: iOS 10.3.x
Mapbox SDK version: 3.6.1

Steps to trigger behavior

1. Subclass MGLAnnotationView adding an UIImageView.
2. Constrain the image view to the edges.
3. Use an image for the normal state and an image for the selected state.
4. Set the selected state of the annotation view.

Expected behavior

The selected view should grow in size and remain in position.

Actual behavior

The annotation view moves to the top left corner.

Note, I tried this without AutoLayout and if you set the frame yourself the pin will also move to top left unless the frame origin is preserved. So it looks like the AutoLayout issue might stem from this?

I modified your sample code: https://gist.github.com/aodhol/c4490cf2063628bf8fb96c637caa43e9 (you will just need to images - a small pin image and a large pin image).

I have same issue connected with AutoLayout. Do you know solution ? Temporary solution for the @aodhol is to use greaterThanOrEqualTo instead of equalTo.

Just a quick guess that this code might be responsible, since it modifies the view’s frame manually rather than using Auto Layout:
