Swift自定义UITableView、UICollectionView

一、在工程里创建MyTableViewCell.swift文件

import UIKitclass MyTableViewCell: UITableViewCell {    var model : Model?    var backView : UIImageView?    var titleLabel : UILabel?    var timeLabel : UILabel?    var likeLabel : UILabel?    override init(style: UITableViewCellStyle, reuseIdentifier: String?) {    super.init(style: style, reuseIdentifier: reuseIdentifier)        self.backView = UIImageView(frame: CGRect(x: 10, y: 0, width: 355, height: 190))        self.backView?.backgroundColor = UIColor.yellowColor()        self.backView?.layer.masksToBounds = true        self.backView?.layer.cornerRadius = 10        self.addSubview(self.backView!)        // 标题        self.titleLabel = UILabel(frame: CGRect(x: 10, y: 0, width: 355, height: 30))        self.titleLabel?.font = UIFont.systemFontOfSize(15)        self.titleLabel?.backgroundColor = UIColor.cyanColor()        self.addSubview(self.titleLabel!)//        self.titleLabel?.text = self.model?.title        // 喜欢        self.likeLabel = UILabel(frame: CGRect(x: 250, y: 160, width: 110, height: 30))        self.likeLabel?.backgroundColor = UIColor.blueColor()        self.addSubview(self.likeLabel!)        // 时间        self.timeLabel = UILabel(frame: CGRect(x: 10, y: 160, width: 100, height: 30))        self.timeLabel?.backgroundColor = UIColor.redColor()        self.addSubview(self.timeLabel!)    }    required init?(coder aDecoder: NSCoder) {        fatalError("init(coder:) has not been implemented")    }    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    }}

二、在ViewController.swift

import UIKit// 网络请求import Alamofireclass ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {    // 定义属性    var myTableView : UITableView？    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view, typically from a nib.        // 创建UITableView        self.myTableView = UITableView(frame: UIScreen.mainScreen().bounds, style: .Plain)        self.myTableView.delegate = self        self.myTableView.dataSource = self        self.view.addSubview(self.myTableView!)         self.myTableView.registerClass(MyTableViewCell.self, forCellReuseIdentifier: "reuse")        // 网络请求        self.getAFNetworkingData()    }    func getAFNetworkingData() {        Alamofire.request(.GET, "http://api.liwushuo.com/v2/channels/111/items?limit=20&offset=0&gender=1")            .responseJSON {response in                debugPrint(response)        }    }    //MARK: UITableViewDataSource    func numberOfSectionsInTableView(tableView: UITableView) -> Int {        return 1    }    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {        return 10    }    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {        let cell = tableView.dequeueReusableCellWithIdentifier("reuse", forIndexPath: indexPath) as! MyTableViewCell        configureCell(cell, forRowAtIndexPath: indexPath)        return cell    }    func configureCell(cell: MyTableViewCell, forRowAtIndexPath: NSIndexPath) {//        cell.textLabel?.text = MyTableViewCell().model?.title//        cell.imageView?.image = UIImage(named: "2.jpg")        cell.model = MyTableViewCell().model    }    // 高度    func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {        return 200    }    // 点击进入下一界面    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {         self.presentViewController(FirstViewController(), animated: true) { () -> Void in        }    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }}

三、下一界面FirstViewController.swift

import UIKitclass FirstViewController: UIViewController {    var myButton : UIButton？    // 自定义View    var myView : BackGroundView？    override func viewDidLoad() {        super.viewDidLoad()        // Do any additional setup after loading the view.        self.view.backgroundColor = UIColor.whiteColor()        self.myButton = UIButton(type: .Custom)        self.myButton.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 100)        self.myButton.setTitle("返回", forState: .Normal)        self.myButton.backgroundColor = UIColor.grayColor()        self.view.addSubview(self.myButton!)        self.myButton.addTarget(self, action: "tap:", forControlEvents: .TouchUpInside)        self.myView = BackGroundView(frame: CGRect(x: 0, y: 110, width: self.view.frame.size.height, height: 400))        self.view.addSubview(self.myView!)    }    func tap(sender : AnyObject) {        self.dismissViewControllerAnimated(true) { () -> Void in        }    }    override func didReceiveMemoryWarning() {        super.didReceiveMemoryWarning()        // Dispose of any resources that can be recreated.    }    /*    // MARK: - Navigation    // In a storyboard-based application, you will often want to do a little preparation before navigation    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {        // Get the new view controller using segue.destinationViewController.        // Pass the selected object to the new view controller.    }    */}

四、自定义BackGroundView.swift里嵌套UICollectionView

import UIKitclass BackGroundView: UIView, UICollectionViewDelegate, UICollectionViewDataSource {    var flowLayout : UICollectionViewFlowLayout = UICollectionViewFlowLayout()    var collectionView : UICollectionView?    override init(frame: CGRect) {        super.init(frame: frame)        flowLayout.itemSize = CGSize(width: frame.size.width, height: frame.size.height)        flowLayout.scrollDirection = .Horizontal        flowLayout.minimumInteritemSpacing = 0        flowLayout.minimumLineSpacing = 0        self.collectionView = UICollectionView(frame: self.bounds, collectionViewLayout: self.flowLayout)        self.collectionView?.delegate = self        self.collectionView?.dataSource = self        self.addSubview(self.collectionView!)        self.collectionView?.registerClass(BackCollectionViewCell.self, forCellWithReuseIdentifier: "reuse")    }    // 类中存在异于父类的初始化方法必须要写    // required    required init?(coder aDecoder: NSCoder) {        fatalError("init(coder:) has not been implemented")    }    // MARK: UICollectionViewDataSource    func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {        return 1    }    func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {        return 100    }    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("reuse", forIndexPath: indexPath) as! BackCollectionViewCell        configureCell(cell, forItemAtIndexPath: indexPath)        return cell    }    func configureCell(cell: BackCollectionViewCell, forItemAtIndexPath: NSIndexPath) {        cell.backgroundColor = UIColor.redColor()    }    /*    // Only override drawRect: if you perform custom drawing.    // An empty implementation adversely affects performance during animation.    override func drawRect(rect: CGRect) {        // Drawing code    }    */}

五、自定义BackCollectionViewCell.swift

import UIKitclass MyModel : NSObject {    var imageUrl : String?    init(imageUrl : String) {        self.imageUrl = imageUrl    }}class BackCollectionViewCell: UICollectionViewCell {    var myView : UIImageView!    var model : MyModel? {        willSet (newValue) {            print(newValue)            print(model)        }        didSet {            print(model?.imageUrl)            self.myView?.image = UIImage(named: (model!.imageUrl)!)        }    }    override init(frame: CGRect) {        super.init(frame: frame)        self.myView = UIImageView(frame: self.bounds)        self.myView.image = UIImage(named: "1.jpg")        self.addSubview(self.myView)    }    required init?(coder aDecoder: NSCoder) {        fatalError("init(coder:) has not been implemented")    }}
