Наконец-то я обнаружил странный крах. Это вызвано тем, что tableView:commitEditingStyle:forRowAtIndexPath:
вызывается с nil
indexPath. Но как это может быть?
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
// DEBUG
if (indexPath == nil) {
NSLog(@"Deleting row at nil indexPath in %@", self);
}
[self deleteItemAtIndexPath:indexPath fromTableView:tableView];
}
}
Вот трассировка стека:
