ViewControllerの実装

ViewController.swift

        }()
    
    override func viewDidLoad() {
        super.viewDidLoad()

        // 以下のように,repeatedValue にクラスを渡すと実体は1つのため状態が共有されてしまうので,実際に使うときは注意
        let cellmodels: [MyCellModel] = Array(count: 4,  repeatedValue: MyCellModel())
        
        let section = SASection()
        section.inset = UIEdgeInsets(top: 30, left: 10, bottom: 10, right: 10)
        section.minimumLineSpacing = 10
        
        sapporo
            .registerCellByNib(MyCell)
            .setLayout(SAFlowLayout())
        
        sapporo
            .reset(section)
            .bump()

            .reset(cellmodels)
            .bump()
    }

}

CellとCellModelの実装

MyCell.swift
import UIKit
import Sapporo

class MyCellModel: SACellModel {

    init(){
        let size = CGSize(width: 100, height: 100)
        super.init(cellType: MyCell.self, size: size, selectionHandler: nil)
    }
}

class MyCell: SACell, SACellType {
    typealias CellModel = MyCellModel
    
    override func configure() {
        super.configure()
        
    }
}

セルの操作

  • 追加

     section
     	.append(cellmodel)
     	.bump()

     	.append(cellmodel)
     	.bump()
    
  • 挿入

     section
     	.insert(cellmodel)
     	.bump()
     	
     section
         .insertBeforeLast(cellmodels)
         .bump()
    
  • リセット

     section
         .reset(cellmodels)              
         .bump()
    
     section
         .reset()                            
         .bump()

         .move(fromIndex: 5, toIndex: 1)
         .bump()
    
  • 削除

     section
         .remove(1)
         .bump()
    
     section
         .remove(cellmodel)
         .bump()
    
     section
         .remove(2...5)
         .bump()
    
     section
         .removeLast()
         .bump()
    
  • 更新

     let cellmodel = section[1]
     cellmodel.property = newData
     cellmodel.bump()
