454 PointsNew verson of CGRectMake Swift 4
I'm trying to make the cells in my collection view expand the entire width of the screen. I tried:
CGSizeMake(view.frame.width, 50)
Im getting an error trying to do this and it saying CGSizeMake isnt available in swift. what should I use instead.
Also below is the code of the functions for the cells
verride func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 3
}
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
return collectionView.dequeueReusableCell(withReuseIdentifier: cellID, for: indexPath)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtsizeForItemAt indexPath: IndexPath) -> CGSize {
// HERE IS WHERE ITS BROKEN have tried multiple things and none of it works
return CGSize(width: 50, height: 50)
}
}
class FeedCell: UICollectionViewCell { override init(frame: CGRect) { super.init(frame: frame) setupViews()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setupViews() {
backgroundColor = UIColor.white
}
}

454 PointsI ended up doing:
if indexPath.section == 1 { return CGSize(width: (view.frame.width / 3) -16, height: 150
}
and that worked without having to create an extension. Thanks for the advice tho. Got me on a good track.

15,994 PointsMake an extension of your collectionViewController conforming to UICollectionViewDelegateFlowLayout. Then just return the CGSize with the frame's width and height.
extension YourCollectionViewController : UICollectionViewDelegateFlowLayout {
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: view.frame.width, height: view.frame.height)
}
}

454 PointsI created an extension and it builds but they are still square. for width i put (width: view.frame.width, 50)

15,994 PointsDo you have a collection view inside a view controller? If so, remember to set your collectionView as a delegate of this view controller.
