I have a multi-platform OpenGL app (most code is c++, a tiny bit is Obj-C++). It switches between windowed and full screen mode by having an allocated-once window, and an allocated-and-destroyed full screen that comes and goes as needed.This worked correctly under Xcode 4. Due to local policy, I was prohibited from upgrading until it suddenly became mandatory, and I jumped from Xcode 4 to Xcode 10. Now my code no longer works correctly. Specifically, the window works, and going to full screen works, but when I try to switch back to windowed mode (by deallocating the full screen window and letting it go away on its own), it no longer goes away. I think I recall something on this list about changes to auto pools and ARC in newer Xcode, but a search didn’t produce it. I’m no expert in Obj-C, so I’m hoping someone can point me in the right direction. My attempts have only resulted in memory faults. Thanks in advance!
I think the trick is that you have to say [window orderOut: something] rather than just releasing the window. Not sure when that changed.
