willMoveToWindow:nil
gets called when the view gets hidden, e.g. when navigating away. The problem here is, that you can navigate back and the view should be active again, but we completely destroy a reference to it in this method.Instead, we should only destroy the reference in
dealloc
.To be a bit more efficient on the CPU we can also think about pausing redraws if
willMoveToWindow
gets called with anil
window and anil
superview, but deleting the reference just causes the app to crash/the view to freeze and no longer update.
