“Unbalanced calls to begin/end appearance transitions for DetailViewController” when pushing more than one detail view controller

by

“The unbalanced calls to begin/end appearance transitions”

occurs when you try and display a new viewcontroller before the current view controller is finished displaying. You can reproduce it by navigating in viewWillAppear.

Basically you are trying to push two view controllers onto the stack at almost the same time. Suggest you maintain a queue in the tableview controller which maintains a list of the detail views which need displaying. Push one at a time on to the stack and check on exit from the current detail view whether there are any queued detail views which need displaying.

This kind of navigation is going to be confusing for the user. It may be better to consider making your detail view support multiple items.
