问题 I have a dynamic NSTableView which can add a number of columns depending on the data provided. For each column I have set the header cell to be a NSPopUpButtonCell. (Side-note: I've had to use a custom subclass class for NSTableHeaderView otherwise the menu doesn't pop-up). All works well, apart from a duplicate or extra header button cell on the top right. It mirrors perfectly the previous column selection as shown in screenshots. My question is how do I stop the NSTableView from recycling
