Changing layout of UICollectionView for each item

I have the code below in my viewDidLoad method.

let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
    layout.sectionInset = UIEdgeInsets(top: 70, left: 10, bottom: 60, right: 10)
    layout.itemSize = CGSize(width: self.view.frame.width - 20, height: 100)
    collectionView = UICollectionView(frame: CGRectMake(0, 75, self.view.frame.width, self.view.frame.height-75), collectionViewLayout: layout)
    collectionView!.dataSource = self
    collectionView!.delegate = self
    collectionView!.registerClass(ChatCellCollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
    collectionView!.backgroundColor = UIColor.clearColor()
    collectionView!.alwaysBounceVertical = true
    self.view.addSubview(collectionView!)

Each item has a UILabel that has the text set from an array. This then determines the height of the UILabel. How can I also resize the height of the items in the collection view to the same as the label? Thanks

Have you tried implementing the UICollectionViewDelegateFlowLayout delegate method 'sizeForItemAtIndexPath" ?

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    return CGSizeMake(label.size.width, label.size.height); 
}
