Here’s some code for a not bad looking little scrunchy push-ish transition for the case of jumping out of one hierarchy and directly to another off the root with a UINavigationController:
There’s a video showing it here as well.
At this exact moment what we want to do is not jump around in a navigation hierarchy but toggle between a navigation stack and a plain UIView, but the code looks pretty applicable to that as well. If we run into any problems with that, we’ll be sure to let you know!
Yep, took us 9 minutes flat to convert the code linked above into a UIWindow method to replace its main view with a transition and test, works perfectly and looks quite appropriate for the use case we’ve got for the switching between error view and navigation stack here. Ex-cellent!
