swift UICollectionView使用

方法1：创建 的时候注册 layout

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

/// 时间view private lazy var timeCollectionV: UICollectionView = {     1.直接注册 并设置好 UICollectionViewFlowLayout     let layout = UICollectionViewFlowLayout()       layout.itemSize = CGSize.init(width: (JY_DEVICE_WIDTH - 60) / 5, height: (JY_DEVICE_WIDTH - 60) / 5)     layout.minimumLineSpacing = 10     layout.minimumInteritemSpacing = 0     layout.sectionInset = UIEdgeInsetsMake(0, 0, 0, 0)           let collectionV = UICollectionView(frame: CGRect.zero, collectionViewLayout: layout)     collectionV.register(UINib.init(nibName: "JYChooseShopTimeCollectionCell", bundle: nil), forCellWithReuseIdentifier: "JYChooseShopTimeCollectionCell")     collectionV.delegate = self     collectionV.dataSource = self     collectionV.backgroundColor = UIColor.white     return collectionV }()

　　2.在代理里面设置UICollectionViewFlowLayout

extension JYBespeakStylistAndTimeVc: UICollectionViewDataSource, UICollectionViewDelegate,UICollectionViewDelegateFlowLayout{

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

//最小行间距     func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {         return 10;     }       //每个分区的内边距     func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAt section: Int) -> UIEdgeInsets {         return UIEdgeInsetsMake(0, 0, 0, 0);     }       //item 的尺寸     func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {           let sizeItem : CGFloat = CGFloat(JY_DEVICE_WIDTH - 60) / 5         return CGSize.init(width: sizeItem, height: sizeItem)     }<br><br>

}

　　

3.其他设置

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13

// 一个分区几行     func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {         return 60     }           //每个cell     func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {                   let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "JYChooseShopTimeCollectionCell", for: indexPath) as! JYChooseShopTimeCollectionCell           //        cell.configModel(model: self.secmentControlTuple.timeArr![indexPath.row])         return cell     }<br><br>

   　　func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {

        

        DDLOG(message: "点击 item")

    }
