iOS开发 Swift开发数独游戏（三） 选关界面

一、选关界面涉及到的功能点

1）需要UITableView以及相应数据代理、协议的实现

2）读取plist文件并转化成模型

3）在单元格点击后进入数独游戏，涉及到把数据经segue在UIViewController间传递

4）记录某一关卡是否通过需要用到NSUserDefaults的存档记录功能

 

先放一张效果图

 

二、具体步骤

1、在

Storyboard中拖入一个TableViewController，勾选”Is Initial View Controller”，如图

为了方便设计，我还将Size 设为“freeform” 长宽设为1024*768

2、新建一个Swift类ChooseGameTableView，令其继承UITableViewController,并实现UITableViewDataSource协议。在之前的ViewController属性列表中Custom Class输入新建的类。

3、在Swift类ChooseGameTableView中设置UITableView以及相应数据代理、协议的实现 ，代码如下

：

   2:  //  ChooseGameTableView.swift

   9:  import Foundation

  10:  import UIKit

  11:  class ChooseGameTableView: UITableViewController,UITableViewDataSource {

  12:      // MARK: - 变量

  13:      //swift貌似现在还不支持#pragma mark 这样的写法

  14:      // 写法参考来源：http://www.tuicool.com/articles/JVZjmm

  15:      var passes = [pass]()

  16:      var touchingP:pass = pass(mytitle: "", isPassed: false, prob: "", solves: [""])

  17:      var touchingCellIndex:NSIndexPath?

  18:      // MARK: - View载入时执行方法

  19:      override func viewDidLoad() {

  20:          //读取plist文件

  21:          var path = NSBundle.mainBundle().pathForResource("sudukuR", ofType: "plist")

  22:          var rootDic = NSDictionary(contentsOfFile: path!)

  23:          var PassNum = 0

  24:          var NotFound = "NotFound"//未找到时的标记符

  25:          for i in 1...81 {

  26:              var tempPasses: AnyObject? = rootDic?.objectForKey("D\(i)")//按挖孔数区分难度进行遍历

  27:              if tempPasses == nil {//如果该挖空数下没有关卡则跳过

  28:                  continue

  29:              }

  30:              var CurrentDPasses  = tempPasses as NSArray //转成NSArray

  31:              for SinglePassDic in CurrentDPasses {//遍历得到每一关的单独关卡（Dictionary格式）

  32:                  //数据转模型，添加进passes中

  33:                  passes.append(pass(mytitle: "第\(++PassNum)关 挖空:\(i)", isPassed: getIsPassedByMD5(SinglePassDic.objectForKey("p") as String), prob: SinglePassDic.objectForKey("p") as String, solves: SinglePassDic.objectForKey("s") as [String]))

  34:              }

  35:          }

  36:          self.tableView.dataSource = self

  37:       }

  38:     

  39:      // MARK: - 检查该关卡之前是否已经通过

  40:      func getIsPassedByMD5(pro:String)->Bool{

  41:          var md5 = (pro as NSString).md5()
