  3. Assign the grid layout to your collection view’s `collectionViewLayout` property.

“`swift
import RDHCollectionViewGridLayout

let gridLayout = RDHCollectionViewGridLayout()
gridLayout.numberOfColumns = 3
gridLayout.interitemSpacing = 10.0
gridLayout.lineSpacing = 10.0

collectionView.collectionViewLayout = gridLayout
“`

Customization

The RDHCollectionViewGridLayout provides various customization options to tailor the grid layout according to your needs.

Grid Properties

You can modify the following properties of the grid layout:

  • `numberOfColumns`: The number of columns in the grid.
  • `interitemSpacing`: The horizontal spacing between grid items.
  • `lineSpacing`: The vertical spacing between grid items.
  • `itemSize`: The size of the grid items.
  • `headerInsets`: The insets of the header view.
  • `footerInsets`: The insets of the footer view.

Example

Here’s an example of how to use the RDHCollectionViewGridLayout:

“`swift
import UIKit
import RDHCollectionViewGridLayout

class MyViewController: UIViewController, UICollectionViewDataSource {
@IBOutlet weak var collectionView: UICollectionView!

let gridLayout = RDHCollectionViewGridLayout()

override func viewDidLoad() {
super.viewDidLoad()

gridLayout.numberOfColumns = 2
gridLayout.interitemSpacing = 10.0
gridLayout.lineSpacing = 10.0

collectionView.collectionViewLayout = gridLayout
collectionView.dataSource = self

// Register your cell class or nib file
collectionView.register(MyCollectionViewCell.self, forCellWithReuseIdentifier: “cellIdentifier”)
}

// Implement UICollectionViewDataSource methods

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return myDataSource.count
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: “cellIdentifier”, for: indexPath) as! MyCollectionViewCell

// Configure your cell

return cell
}
}
“`
