NSUnknownKeyException setValue:forUndefinedKey:
ios5, iphone, nsexception, uitableview
Solution
Check your references of your outlets in your XIB, one of them is probably referencing a property (buttonOfFirstView) that does not exist anymore
Problem
Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key buttonOfFirstView.' Why do I get this error? I am trying to make a table cell though XIB. After I add this code it throws the above exception. ``` - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *CellIdentifier = @"MyCell"; MyTableViewCell *cell = (MyTableViewCell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *arrayCellXib = [[NSBundle mainBundle] loadNibNamed:@"MyTableViewCell" owner:self options:nil]; .... } ..... return cell; } ``` How to resolve it?
