So today I implement landscape mode for my app. It is an opengl es application. I rotated it 90 degrees. The first thing I notice is that the touches no longer work. The reason being is that the call to locationInView is still giving the coordinates as though the application is in portrait mode.
How do people typically deal with this? Do I have to write my own version of locationInView to take into account the orientation of the phone? Or is there a better way?
That’s default behavior. Whether the iPhone is in portrait or landscape the screen coordinates don’t change, so you’ll need to adjust for that in your app.
