Swift实战（一）: 剪子包袱锤ios应用

来自十奶的大作业教学视频。

主要了解了MVC模型。

首先是View，通过设计mainstoryboard构建UI界面，主要靠拖动，用到了label和button。

接着是model，设计RPS（剪子包袱锤）结构体，见Rps.swift。

12 struct Rps{
13     private var stat:Stats!
14     
15     enum Stats {
16         case Rock
17         case Scissor
18         case Paper
19     }
20     
21     func getStats () -> Stats {
22         return stat
23     }
24     
25     mutating func setStats (inputStat: Stats!) {
26         stat=inputStat
27     }
28     
29     func randomRps () -> Stats{             //生成一个随机的手势
30         let randomNumer = arc4random_uniform(3)
31         var randomStat:Stats!
32         switch randomNumer{
33         case 0:
34             randomStat =  .Rock
35         case 1:
36             randomStat = .Scissor
37         case 2:
38             randomStat = .Paper
39         default:
40             print("Error")
41         }
42         return  randomStat
43     }
44     
45     func compare (aRpsStat:Stats, anotherRpsStat:Stats) -> Int {
46         //返回三种状态，0为前者数，1为前者赢，2为平局
47         var result:Int!
48         switch aRpsStat {
49         case .Rock:
50             switch anotherRpsStat{
51             case .Rock:
52                 result=2
53             case .Scissor:
54                 result=1
55             case .Paper:
56                 result=0
57             }
58             
59         case .Scissor:
60             switch anotherRpsStat{
61             case .Rock:
62                 result=0
63             case .Scissor:
64                 result=2
65             case .Paper:
66                 result=1
67             }
68             
69         case .Paper:
70             switch anotherRpsStat{
71             case .Rock:
72                 result=1
73             case .Scissor:
74                 result=0
75             case .Paper:
76                 result=2
77             }
78             
79         }
80         return result
81 }
82 
83 }

最后是control，即ViewControl.swift，要和mainstoryboard关联起来，靠outlet和action。

    //全局初始化
    func resetAll(){
        textUp.text = ""
        textDown.text = ""
        rps.setStats(nil)
    }
    
    //判断输赢
    func judgement () {
        let randomRps=rps.randomRps()
        let currentStat=rps.getStats()
        let result = rps.compare(currentStat, anotherRpsStat: randomRps)
        screen(result,stat:currentStat,anotherStat:randomRps)
    }
   
    
    //控制显示的方法
    func screen(result:Int,stat:Rps.Stats,anotherStat:Rps.Stats){
        var resultString=""
        var statString=""
        var anotherString=""

        case 1:
            resultString="赢"
        case 2:
            resultString="竟然平局"
        default:
            resultString="醉"
        }
        
        switch stat{
        case .Rock:
            statString = "👊"
        case .Scissor:
            statString = "✌️"
        case .Paper:
            statString = "✋"
        }
        
        switch anotherStat{
        case .Rock:
            anotherString = "👊"
        case .Scissor:
            anotherString = "✌️"
        case .Paper:
            anotherString = "✋"
        }
        
        textUp.text = "你" + resultString + "了！"
        textDown.text = "你出了" + statString + "，但电脑出了" + anotherString + "!"
        
    }
