集合视图设计布局 Ios

Collection View Design Layout Ios

所以,我现在正在制作一个带有集合视图布局的应用程序,并且想知道如何着手设计它以使其看起来不错。我在网上找到了一张我想要它看起来像的图片,并且想知道我应该如何制作它。

图片如下:

我要复制的集合视图是中间那个。

这是我当前的单元格的样子:

第一个答案后我的细胞:

这是我当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!
}

我的猜测是制作我想要的设计有两个主要方面,这让我想到了两个具体问题。

  1. 如何使单元格具有圆角?
  2. 我如何 space 从屏幕侧面创建一个单元格并减少单元格之间的间隙?

ViewController Class

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 Class

class YourCollectionViewCell:UICollectionViewCell{

    override func awakeFromNib() {
            super.awakeFromNib()
            self.layer.cornerRadius = 10 //customize yourself
            self.layer.masksToBounds = true
        }
    }
