Swift 学习 第3天 - UITableViewCell

UITableViewCell

cell 实现

//

import UIKit
import SnapKit

class BaseTableViewCell: UITableViewCell
{
    class func initWithTableViewCell(_ tableView: UITableView, _ indexPath: NSIndexPath, _ Identifier: String) -> BaseTableViewCell
    {
        var cell = BaseTableViewCell()
        cell = tableView.dequeueReusableCell(withIdentifier: Identifier, for: indexPath as IndexPath) as! BaseTableViewCell
        return cell
    }
    
    // 根据model 填充Cell
    func cellForModel(model: BaseModel?) {
        if let tempModel = model {
            nameLb.text = tempModel.name
        }
    }
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        setupUI()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    fileprivate lazy var nameLb : UILabel = {
        let nameLb = UILabel()
        nameLb.backgroundColor = UIColor.orange
        nameLb.text = "哈哈哈"
        nameLb.textColor = .white
        nameLb.font = .systemFont(ofSize: 14)
        return nameLb
    }()
    
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
        // Configure the view for the selected state
    }
    
}


extension BaseTableViewCell
{
    fileprivate func setupUI() {
        
        setupTitleLabels()
    }
    
    fileprivate func setupTitleLabels() {
        
        self.contentView.addSubview(nameLb)
        nameLb.snp.makeConstraints { make in
            make.left.equalTo(15)
            make.centerY.equalTo(self.contentView)
        }
        
    }
}

VC 实现

//

import UIKit
import SnapKit

private let NormalCellID = "BaseTableViewCell"

class AVC: BaseVC {
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.backgroundColor = XColor.x_randomColor
        setupUI()
        AddNavUI()
    }
    
    // MARK: ----- lazy
    private lazy var tableView: UITableView = {
        let tableView = UITableView(frame: CGRect.zero, style: .plain)
        tableView.register(BaseTableViewCell.self, forCellReuseIdentifier: NormalCellID)
        tableView.separatorStyle = .none
        tableView.delegate = self
        tableView.dataSource = self
        //tableView.backgroundColor = XColor.x_randomColor
        return tableView
    }()
    
    private lazy var dataArys: NSMutableArray = {
        let dataArys = NSMutableArray()
        return dataArys
    }()
    
}

// MARK: ----- UI
extension AVC
{
    
    private func setupUI() {
        view.addSubview(tableView)
        tableView.snp.makeConstraints { (make) in
            make.top.equalTo(TopHeight)
            make.left.right.bottom.equalTo(0)
        }
        
        for i in 0 ..< 100
        {
            let model = BaseModel()
            model.name = "哈哈哈" + " \(i) "
            dataArys.add(model)
        }
        tableView.reloadData()
    }
    
    func AddNavUI() {
        
        let homeNav = XNavView()
        homeNav.titleName = "个人中心"
        homeNav.isBackBtnHid = false
        homeNav.onBackBlock = { isok in
            self.navigationController?.popViewController(animated: true)
        }
        homeNav.navLineColor = .red
        view.addSubview(homeNav)
        homeNav.snp.makeConstraints { make in
            make.left.top.right.equalTo(0)
            make.height.equalTo(TopHeight)
        }
        
    }
    
}

// MARK: ----- tableview 代理
extension AVC: UITableViewDelegate,UITableViewDataSource
{
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        dataArys.count
    }
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        50
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        let cell = BaseTableViewCell.initWithTableViewCell(tableView, indexPath as NSIndexPath, NormalCellID)
        cell.cellForModel(model: (dataArys[indexPath.row] as! BaseModel))
        return cell
        
//        let cell = tableView.dequeueReusableCell(withIdentifier: "BaseTableViewCell", for: indexPath) as! BaseTableViewCell
//        cell.textLabel?.text = "---------\(indexPath.row)"
//        cell.backgroundColor = XColor.x_randomColor
//        return cell;
    }
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
        let skinvc = ASkinVC()
        self.navigationController?.pushViewController(skinvc, animated: true)
    }
}
