collection view had multiple images working fine. it's showing like this
But i want show like this way
this is code of collection view cell
let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
layout.sectionInset = UIEdgeInsets(top: 10, left: 0, bottom: 20, right: 0)
let width = UIScreen.main.bounds.width
layout.itemSize = CGSize(width: width/2 , height: width/2 )
layout.minimumInteritemSpacing = 0
layout.minimumLineSpacing = 0
collectionView!.collectionViewLayout = layout
Just implement some UICollectionViewDelegateFlowLayout
methods to get the correct size and spacing of the UICollectionViewCells
.
Example:
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize
{
let cellSize = CGSize(width: (collectionView.bounds.width - (3 * 10))/2, height: 120)
return cellSize
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat
{
return 10
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets
{
let sectionInset = UIEdgeInsetsMake(10, 10, 10, 10)
return sectionInset
}
Just change the size and spacing values according to your requirement.
Add this method on your viewcontroller
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: IndexPath) -> CGSize {
return CGSize(width: ((self.view.frame.size.width/2) - 10), height: 255)
}
尝试,
collectionViewCellImageView.contentMode = .scaleToFill
You can try to set minimum spacing for cell & line for collection view and implement the bellow delegate
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: (collectionView.frame.width/2) - 5, height: collectionView.frame.width/2)
}
