Swift纯代码自定义Cell

最近在自学Swift，想要写一个自定义Cell，可是网上查了好多资料发现大家都是跟Xib结合使用的，本人对Xib不是特别擅长，所以想实现一款纯代码的自定义Cell

首先需要构建一个TableView

class MainViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
 var mainTable: UITableView?
   var mainArray: NSMutableArray?
    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        self.view.backgroundColor = UIColor.whiteColor()
        self.title = "下厨房"
        
        self.setUpTable()
        self.loadDataSource()
    }
    
    // MARK: - tableView Delegate && tableView DataSource
    func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }
    
    func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        return 180
    }
    
    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        print(mainArray!.count)
        return mainArray!.count
    }
    
    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let identifier = "mainCell"
        let cell = MainClassicalCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: identifier)
        
        //下面两个属性对应subtitle
//        cell.firstTitle?.text = mainArray![indexPath.row] as? String
//        cell.subTitle?.text = mainArray![indexPath.row] as? String
        
        var dic = Dictionary<String, String>()
        dic["name"] = mainArray![indexPath.row] as? String
        cell.setValueForCell(dic)
        
        //添加照片
//        cell.showImage?.image = UIImage(named: mainArray![indexPath.row] as! String)
        
        return cell
    }
    
  
    func loadDataSource() {
        mainArray = NSMutableArray.init(array: ["宝宝0", "宝宝1", "宝宝2", "宝宝3", "宝宝4", "宝宝5", "宝宝6", "宝宝7", "宝宝8", "宝宝9", "宝宝10", "宝宝11"])

        self.mainTable?.reloadData()
    }
    
    func setUpTable(){
        mainTable = UITableView.init(frame: CGRectMake(0, 0, SCREENWIDTH, SCREENHEIGHT) , style: UITableViewStyle.Grouped)
        mainTable!.delegate = self
        mainTable!.dataSource = self
        mainTable!.backgroundColor = UIColor.whiteColor()
        self.view.addSubview(mainTable!)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

自定义Cell

import UIKit

class MainClassicalCell: UITableViewCell {
    
    var showImage   : UIImageView?
    var firstTitle  : UILabel?
    var subTitle    : UILabel?
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }
    
    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        self.setUpUI()
    }
    
    func setUpUI() {
        showImage = UIImageView.init(frame: CGRectMake(5, 5, SCREENWIDTH-10, 170))
        showImage!.layer.masksToBounds = true
        self.addSubview(showImage!)
        
        subTitle = UILabel.init(frame: CGRectMake(10, 150, (showImage?.frame.size.width)!-20, 12))
        subTitle?.font = UIFont.systemFontOfSize(15)
        subTitle?.textAlignment = NSTextAlignment.Center
        subTitle?.textColor = UIColor.redColor()
        self.addSubview(subTitle!)
        
        firstTitle = UILabel.init(frame: CGRectMake(10, CGRectGetMinY((subTitle?.frame)!)-38, (subTitle?.frame.size.width)!, 30))
        firstTitle?.font = UIFont.systemFontOfSize(18)
        firstTitle?.textAlignment = NSTextAlignment.Center
        firstTitle?.textColor = UIColor.blueColor()
        self.addSubview(firstTitle!)
    }

    func setValueForCell(dic: NSDictionary) {
        subTitle!.text = "45道菜谱"
        firstTitle!.text = "世界各地大排档的招牌美食"
        showImage!.image = UIImage(imageLiteral: "img.jpg")
    }

    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
    }

}
