Pushing a navigation controller is not supported e

问题:

I am working on an app where the user has the possibility to add products and those products are then displayed in a TableView. I created a TableViewController with static cells and two sections and I want to hook the cell in the second section with another TableViewController.

I dragged the TableViewController from the object library, embedded it in a navigation controller and made a push segue from the cell to the NavigationController but when I try to run the app I get the following error message in the output window:

2013-03-20 09:55:32.981 STAM[725:c07] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported' First throw call stack: (0x1d04012 0x11e8e7e 0x22a5b0 0x22a098 0x585da3 0x577ad9 0x577b54 0x1df899 0x1dfb3d 0xbe6e83 0x1cc3376 0x1cc2e06 0x1caaa82 0x1ca9f44 0x1ca9e1b 0x1f3c7e3 0x1f3c668 0x13065c 0x2a6d 0x2995) libc++abi.dylib: terminate called throwing an exception

Here's a screenshot form my storyboard.

Thank you very much!

Your UINavigationController is at the wrong place. It should be before the UITableViewController.

You can select the UITableViewController from story board then from menu: Editor > Embed In > Navigation Controller.

You can get more info about the navigation stack from the reference guide.
