ios - tableView:canEditRowAtIndexPath: crash when popping viewController

Question

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

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {

    return YES;
}

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

[ViewController tableView:canEditRowAtIndexPath:]: message sent to deallocated instance 0xaae64d0

How can I resolve this problem?

Answer 1

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