Question

I’ve integrated Oomph MacMapKit in one of my projects, I did all the steps. But there is a problem.
I’m using a NSToolbar and switching between the views. whenever I’m in my map page if I switch into another page and then switch back to the map page, the map is drew under the MKMapView and MKMapView is white but I can navigate in map by dragging mouse in the white area.

I’ve tried it in another project as well, And it acts just like this again.

Normal Look

After switching back

Does anyone know how can I fix this?

This code is running in my window controller delegate for switching pages

- (NSView*)viewForTag:(int)tag
{
    switch (tag)
    {
        case 0:
            return [firstViewController view];
            break;
        case 1:
            return [secondViewController view];
            break;
        default:
            return [firstViewController view];
            break;
    }
}

- (IBAction)switchViews:(id)sender
{
    NSView* currentView = [self viewForTag:[sender tag]];
    NSView* previousView = [self viewForTag:currentViewTag];

    currentViewTag = [sender tag];

    [[[[self window] contentView] animator] replaceSubview:previousView with:currentView];
}

There is no special code in maps page.

Thanks in advance

This Map Kit is a bit buggy sometimes, changing my way of presenting views solved the problem.
