swift use button to let collectionView be hidden

Question

Thank you for reading my question, like the title says, how can I use a button to control the collectionView show/hide like hidden = false.

I want the collectionView to hide it in viewDidload(ViewController) method and show when I press the button.

func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath 
    indexPath: NSIndexPath) 
    {
        collectionView.hidden = true
    }

I just can call collectionView in func , How can I do this?

In viewDidLoad, self.collectionView.hidden = true. Then you can toggle the hide/show using the following method:

@IBAction func toggleCollectionViewHideShow(sender: UIButton) {
   self.collectionView.hidden = !self.collectionView.hidden
}
