CheckBox in tableview

Question

I am facing trouble in putting check boxes into a UITableView. I am posting a part of my code here.

- (NSCell *)tableView:(NSTableView *)tableView dataCellFo         


        

Answer 1

I'm not sure why you're creating the cell in code. You can just drag the cell onto the table column in Interface Builder.

Also, setObjectValue: is where you respond to the change in the cell's state. The user has already changed the cell's state to off; then you send setNextState and change it back. That's why the cell doesn't appear to uncheck: you keep re-checking it.

What you need to do is not touch the cell at all, but set the object value (which, for this column, will probably be a Boolean NSNumber containing either YES or NO) as the new value of the appropriate property in your model.

Also, of course, make sure the column is set as editable.
