iOS 7: on textfield did change the firstresponder my application is crashing

Question

I have editable tableview cell,and when i move from first textfield to last textfield in the table it is crashing.Code is.The below code is for textfield delegate

Answer 1

May be this answer somewhat is stupid but the correct answer. I have checked for tableview cellforrowatindexpath and added an identifier

static NSString *EditableTextFieldCellIdentifier = @"EditableCell";

// using custom cells to show textfield and multiple columns
EditableTextFieldCell *cellText = [tableView dequeueReusableCellWithIdentifier:EditableTextFieldCellIdentifier];

And this fixed my problem and also crash.
