所以,我现在正在制作一个带有集合视图布局的应用程序,并且想知道如何设计它以使其看起来不错。我在网上发现了一张我希望它看起来像的图片,并想知道我应该如何制作它。
这是图片:
我想要复制的集合视图是中间的那个。
以下是我当前细胞的样子:
第一个回答后的我的细胞:
这是我目前配置单元格的代码:
override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "channelCell", for: indexPath) as? ChannelCollectionViewCell
let channel = channels[indexPath.row]
// Configure the cell
cell?.configureCell(channel: channel)
return cell!
}
我的猜测是,我想要的设计有两个主要内容,它带给我两个具体的问题。
答案 0 :(得分:1)
ViewController类
class YourClass: UIViewController {
//MARK:-Outlets
@IBOutlet weak var yourCollectionView: UICollectionView!
//Mark:-Variables
var cellWidth:CGFloat = 0
var cellHeight:CGFloat = 0
var spacing:CGFloat = 12
var numberOfColumn:CGFloat = 2
//MARK:-LifeCycle
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
yourCollectionView.contentInset = UIEdgeInsets(top: spacing, left: spacing, bottom: spacing, right: spacing)
if let flowLayout = yourCollectionView.collectionViewLayout as? UICollectionViewFlowLayout{
cellWidth = (yourCollectionView.frame.width - (numberOfColumn + 1)*spacing)/numberOfColumn
cellHeight = 100 //yourCellHeight
flowLayout.minimumLineSpacing = spacing
flowLayout.minimumInteritemSpacing = spacing
}
}
extension YourClass:UICollectionViewDataSource{
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 10
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as? YourCollectionViewCell{
//Configure cell
return cell
}
return UICollectionViewCell()
}
}
extension YourClass:UICollectionViewDelegateFlowLayout{
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
return CGSize(width: cellWidth, height: cellHeight)
}
}
CollectionViewCell类
class YourCollectionViewCell:UICollectionViewCell{
override func awakeFromNib() {
super.awakeFromNib()
self.layer.cornerRadius = 10 //customize yourself
self.layer.masksToBounds = true
}
}
