Summary:
I have a tab view controller which has 2 tab with navigation controller in both tab.
I have a UITableViewController which I manage its view by creating a new view and then add the superclass’s table view to it as a subview. I push this view controller onto a UINavigationController. I open another tab in then also push my UITableViewController when I call popViewController on both navigation controller then switch back, Application will crash.
it said that UITableView try to access its delegate which already dealloc. The Navigation Controller still has the UITableView in its subview which it shouldn’t

Steps to Reproduce:
1. Open Sample Projejct
2. IN first tab, tap the first row to push into my UITableViewController
3. In second tab, tap the first row to push into my UITableViewController too.
4. Top the button in navigation bar to make both UINavigationController to call popViewController
5. Switch back to the first tab.

Expected Results:
Shows the navigation controller with its root view.

Actual Results:
Application crash.

Regression:
iOS 7 doesn’t crash.
