I have a subclass of tableview cell which needs to have a UICollectionView inside it. I am now facing issues while trying to add a UICollectionView. It is letting me add a new UICollectionView but I am unable to set its constrains. Below is my code for doing the same:
// Add Collection
let layout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 20, left: 10, bottom: 10, right: 10)
collectionProducts = UICollectionView(frame: CGRect.zero, collectionViewLayout: layout)
contentView.addSubview(collectionProducts)
let leadingColConstraint = NSLayoutConstraint(item: collectionProducts, attribute: NSLayoutAttribute.leadingMargin, relatedBy: NSLayoutRelation.equal, toItem: contentView, attribute: NSLayoutAttribute.leadingMargin, multiplier: 1, constant: 0)
let trailingColConstraint = NSLayoutConstraint(item: collectionProducts, attribute: NSLayoutAttribute.trailingMargin, relatedBy: NSLayoutRelation.equal, toItem: contentView, attribute: NSLayoutAttribute.trailingMargin, multiplier: 1, constant: 0)
let topColConstraint = NSLayoutConstraint(item: collectionProducts, attribute: NSLayoutAttribute.top, relatedBy: NSLayoutRelation.equal, toItem: lblHeader, attribute: NSLayoutAttribute.bottom, multiplier: 1, constant: 62)
let bottomColConstraint = NSLayoutConstraint(item: collectionProducts, attribute: NSLayoutAttribute.top, relatedBy: NSLayoutRelation.equal, toItem: contentView, attribute: NSLayoutAttribute.bottom, multiplier: 1, constant: 55)
contentView.addConstraints([leadingColConstraint,trailingColConstraint,topColConstraint,bottomColConstraint])
collectionProducts.translatesAutoresizingMaskIntoConstraints = false
Am I missing anything? I am a relatively late mover to Swift and also relatively new to creating the cells programmatically. I can easily do the same using nib or storyboard, but I am stuck here. Kindly help be out.
