I'm having a NSCollectionView consist of 10 NSButtons and also dragged a NSpanel from object library. If i click a button NSpanel should be appeared.If i clicked the next button, last generated NSpanel should closed and another NSpanel was opened. What my problem is the NSpanel was generated, if i clicked the Second Button another NSpanel appeared and the previous one was not closed.
