UItableView自定义&封装
一：Model
1 class AppsModel: NSObject {
2
3 //定义模型的三个属性
4 var imageName:String! //图片名称
5 var appName:String! //应用名称
6 var appDescription:String! //应用描述
7
8
9
10 //自定义初始化方法
11 init(imageName image_Name:String , app_Name:String , app_Description:String) {
12 self.imageName=image_Name
13 self.appName=app_Name
14 self.appDescription=app_Description
15 }
16
17
18
19 // MARK: - NSCoding
20 func encodeWithCoder(_encoder: NSCoder)
21 {
22 _encoder.encodeObject(self.imageName, forKey: "M_imageName")
23 _encoder.encodeObject(self.appName, forKey: "M_appName")
24 _encoder.encodeObject(self.appDescription, forKey: "M_appDescription")
25 }
26
27
28 init(coder decoder: NSCoder)
29 {
30 // imageName = decoder.decodeObjectForKey("M_imageName") as String
31 // appName = decoder.decodeObjectForKey("M_appName") as String
32 // appDescription = decoder.decodeObjectForKey("M_appDescription") as String
33
34 //2015年5月2号修改
35 imageName = decoder.decodeObjectForKey("M_imageName") as! String
36 appName = decoder.decodeObjectForKey("M_appName") as! String
37 appDescription = decoder.decodeObjectForKey("M_appDescription") as! String
38 }
39
40 }
二：View
1 class MyTableViewCell: UITableViewCell {
2
3 var iconImageView:UIImageView! //图片
4 var appNameLabel:UILabel! //标题
5 var decLabel:UILabel! //描述
6
7 //赋值方法 - 显示cell内容方法
8 func showAppInfoWithModel(model:AppsModel)
9 {
10 //获取model中得图片
11 iconImageView.image = UIImage(named: model.imageName)
12
13 //获取model中app名称
14 appNameLabel.text = model.appName
15
16 //获取model中app描述
17 decLabel.text = model.appDescription
18 }
19
20 override init(style: UITableViewCellStyle, reuseIdentifier: String?)
21 {
22 super.init(style: style, reuseIdentifier: reuseIdentifier)
23
24 //创建iconImageView
25 iconImageView = UIImageView(frame: CGRectMake(10, 5, 40, 40))
26 self.addSubview(iconImageView)
27
28 //创建appNameLabel
29 appNameLabel = UILabel(frame: CGRectMake(60, 0, 220, 15))
30 appNameLabel.font = UIFont.systemFontOfSize(16)
31 self.addSubview(appNameLabel)
32
33 //创建decLabel
34 decLabel = UILabel(frame: CGRectMake(60, 15, 220, 35))
35 decLabel.font = UIFont.systemFontOfSize(12)
36 decLabel.numberOfLines = 2
37 decLabel.textColor = UIColor.lightGrayColor()
38 self.addSubview(decLabel)
39
40 }
41
42 required init(coder aDecoder: NSCoder) {
43 fatalError("init(coder:) has not been implemented")
44 }
45
46
47
48 override func awakeFromNib() {
49 super.awakeFromNib()
50 // Initialization code
51 }
52
53 override func setSelected(selected: Bool, animated: Bool) {
54 super.setSelected(selected, animated: animated)
55
56 // Configure the view for the selected state
57 }
58
59 }
三：Controller
1 class UITableViewControllerCustom: UIViewController, UITableViewDataSource, UITableViewDelegate {
2
3 var titleString:String!
4
5 @IBOutlet var titleLabel:UILabel!
6 @IBOutlet var listTableView : UITableView!
7
8
9 //定义数组
10 var items:[AppsModel]!
11
12
13 //返回按钮事件
14 @IBAction func backButtonClick()
15 {
16 self.navigationController?.popViewControllerAnimated(true)
17 }
18
19
20 override func viewDidLoad() {
21 super.viewDidLoad()
22
23 titleLabel.text = titleString
24
25 //定义三个模型对象
26 var model1:AppsModel = AppsModel(imageName: "appIcon1.png", app_Name: "Football Maze", app_Description: "足球迷宫，迷宫的新玩法，益智虚拟迷宫游戏。快来挑战你的空间想象，足球迷宫带你到一个不同的世界… 迷宫大家都在玩，你还在等什么。")
27 var model2:AppsModel = AppsModel(imageName: "appIcon2.png", app_Name: "租房点评", app_Description: "租房被骗？现在开始，你来改变这一切！《租房点评》为你而备，租房无忧！")
28 var model3:AppsModel = AppsModel(imageName: "appIcon3.png", app_Name: "iJump", app_Description: "摇动手机，松鼠就可以运动啦，越跳越高，注意会有虫子咬坏跳板哦，祝你玩得开心")
29 var model4:AppsModel = AppsModel(imageName: "appIcon4.png", app_Name: "哪里逃", app_Description: "哪里逃 是一款躲避类游戏，拖动美女图片，躲避，追来的帅锅，帅锅人数越来越多，不要被追到哦。")
30
31 //修改数组值
32 items = [model1,model2,model3,model4]
33
34 //TabelView刷新
35 listTableView.reloadData()
36
37 // Do any additional setup after loading the view.
38 }
39
40 override func didReceiveMemoryWarning() {
41 super.didReceiveMemoryWarning()
42 // Dispose of any resources that can be recreated.
43 }
44
45
46 /*
47 // MARK: - Navigation
48
49 // In a storyboard-based application, you will often want to do a little preparation before navigation
50 override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
51 // Get the new view controller using segue.destinationViewController.
52 // Pass the selected object to the new view controller.
53 }
54 */
55
56
57 //MARK: - UITableViewDelegate
58 //tableView数据源：返回行数
59 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
60 {
61 return items.count
62 }

65 func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat
66 {
67 return 50
68 }
69
70 //tableView数据源：每一行内容
71 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
72 {
73 //Cell标示符，代表一系列
74 // OC：使用static， swift：使用let
75 let cellIdentifier: String = "cellIdentifier"
76
77 //通过cellIdentifier标示符取没有使用的Cell
78 //有可能不存在，所以使用：optional
79 var cell: MyTableViewCell? = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as? MyTableViewCell
80
81 //如果cell取到是空
82 if cell == nil { // no value
83
84 //创建新的MyTableViewCell实例

101
102 var cellModel:AppsModel = self.items[indexPath.row]

105 cell?.showAppInfoWithModel(cellModel)
106

108 }
109
110 //tableView代理：点击一行
111 func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
