iOS Error Occurs when Changing UITableView loaded from nib to Subclassing UITableView

[roeik]

HI,

I just modified a class on my iPhone app. It used to load a UITableView from a nib, but now I am just subclassing UITableViewController:

@interface DetailViewController : UITableViewController

When I build the app on a device that has a previous version installed, the app crashes and I get an error. However, when I delete the app from the simulator/device and build it again the issue is resolved. I tested this on 3 devices running pervious versions of the app. All give the following error, which as I said disappear when I delete the app from the device and rebuild it:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "DetailViewController" nib but didn't get a UITableView.'
*** First throw call stack:

libc++abi.dylib: terminating with uncaught exception of type NSException

My question is, can I safely submit the new version to the app store without being concerned it will cause a crash to users that update the app?

Thank you,

It's hard to know the answer.

The way to test this is with an adhoc build. Load your App Store version. Then update it with an adhoc build using iTunes or Xcode. Then see what happens. That is the closest to what a real user will experience.

Needless to say, you should always do this with new versions to be submitted to the app store.
