I have a viewcontroller with a UITableView , the rows of which I allow to edit (delete) with a swipe-much as in the Mail app. I do it with, among other, this method:

  -  (bool) tableview:( Uitableview *) tableview Caneditrowatindexpath :(nsindexpath *) { return Yes}             /span>            

However, if I has a delete button revealed, and at the same time I use back navigation of my UINavigationController , i.e. when I popViewControllerAnimated: , th E app crashes with the following message:

[Viewcontroller Tableview:caneditrowatindexpath:]: Message sent to deallocated instance 0xaae64d0

How can I resolve this problem?

In your view controller ' s dealloc method, set the table view's property to editing NO .

this works but it is only started happening in IOS7. Any idea Why? –  imran oct "at 10:49

at first, I thought this is a random CR Ash because of system bugs because Crashlytics tells me only few people (out of thousands) have this issue. Now I know why and get my app Fixed! –  benck feb" at 9:17

I had the same problem, but I am using ARC and I didn ' t want to being mucking about in the Dealloc method. Doing it in Viewwilldisappear is sufficient to stop the crash.

- (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [table setEditing:NO];}

is it wrong to a dealloc method un Der ARC as long as you don ' t call [Super dealloc]? –  artooras  Oct 9 ' at 9:27

it ' s not wrong. The accepted answer won ' t break anything and would compile normally. You literally won ' is allowed to call  [Super Dealloc]  or  release  as ARC is supposed to call them for you. My suggestion is mostly to reduce confusion since I didn ' t want a unusual dealloc method when none of my other classes H Ave One. It also feels weird to being setting a property in an object moments before it'll likely be released. –  nat Han Rabe oct 9 ' at 15:39
this method would sometimes cause weird behaviour if you present other VCs etc so I Wou LD Use the Dealloc method. –  imran oct" at 10:51
viewdiddisappear:  also Works, which I prefer in this case as the User doesn ' t see the TableView transitioning out of the editing State. –  defragged mar 6 ' + at 13:20
