In my ignorance, I would suspect that there might be two factors at play. One being gesture tracking applied to which object/view, the other being initialization of the image scale in the view of the subview when the scene is being drawn.
Out of curiosity, how does the image scale behave when you set a minimum zoom size? What I have seen is that there are many unseen inherited operations and we don't see what gets called when as items appear. For instance, I could not set the frame of a storyboarded 1/2 screen TVC on viewDidLoad, or viewWillAppear but setting it on viewDidAppear work just fine without any visual artifacts that I would have expected. My suspicion would be that you need to identify the event chain when the view appears and for giggles, see if you can manually set the scale of the zoom at different events and record where it fails and where it works. Once you find where it works, track down the reason why and work within the initialization routines. FYI, this is one of my gripes with OC. There is no way to see the parent method invocation chain in the source. It would rock if you had an option to see this at a 50% transparency so that you could see the inherited methods that are called which set up your display and you have little knowledge about. GL.
