Add setter method for the View.projection_ field. about openlayers HOT 3 OPEN

It would be possible to add that, but usually it is easier to do what you are currently doing - creating a new View and call map.setView(newView). I don't see how this would be more complex than setting a projection, calculating the new center and zoom, and set the resulting properties on an existing view.

It makes sense to create a new view as center and resolution must also change when the projection changes. As long as the projections are defined using proj4 and their extents overlap the onChangeProjection function in https://openlayers.org/en/latest/examples/projection-and-scale.html should work for any combination of projections.

Yeah I didn't explain much. The reason why it's adding complexity is because for this project I'm setting many listeners on the view for different purposes. So any time I'm replacing the old view by the new one I have to unset the listeners on the old one, and reset all of them for the new view. And this has to be done any time we change projection, so with the UTM/UPS system it can be very frequent (nearly every mouse drag).

This is indeed the work from which one I started.
