DatePicker練習 計算生命靈數

兩光師來算命囉

來幫自己算算命吧!!

SeaFood不好意思，借我練習一下><

用到的功能：

1. UIDatePicker
2. UIButton

能觸發的IBAction有

1. 嗯…就只有UIButton，按下Button後，會抓取選取的日期，

再來是計算出年紀.星座.生肖及生命密碼

而我的習慣是把資訊都用陣列包起來，包含星座.生肖及狀態

//預設陣列
    var newConstellation = ["水瓶座","雙魚座","白羊座","金牛座","雙子座","巨蟹座","獅子座","處女座","天秤座","天蠍座","射手座","摩羯座"]
    var newAnimal = ["鼠","牛","虎","兔","龍","蛇","馬","羊","猴","雞","狗","豬"]
    var passwdStatusMessage = ["","財運","事業","愛情","親情","友情","運氣","健康","眼睛","學業","天氣"]

處理星座：基本上判斷日期後，抓取陣列內的第N筆

//處理星座
        let constellationNumber: Int
        if month == 1 && day >= 19 || month == 2 && day <= 19 {
            //水瓶座
            constellationNumber = 0
        }else if month == 2 && day >= 20 || month == 3 && day <= 20 {
            //雙魚座
            constellationNumber = 1
        }else if month == 3 && day >= 21 || month == 4 && day <= 20 {
            //白羊座
            constellationNumber = 2
        }else if month == 4 && day >= 21 || month == 5 && day <= 20 {
            //金牛座
            constellationNumber = 3
        }else if month == 5 && day >= 21 || month == 6 && day <= 20 {
            //雙子座
            constellationNumber = 4
        }else if month == 6 && day >= 21 || month == 7 && day <= 22 {
            //巨蟹座
            constellationNumber = 5
        }else if month == 7 && day >= 23 || month == 8 && day <= 22 {
            //獅子座
            constellationNumber = 6
        }else if month == 8 && day >= 23 || month == 9 && day <= 22 {
            //處女座
            constellationNumber = 7
        }else if month == 9 && day >= 23 || month == 10 && day <= 22 {
            //天秤座
            constellationNumber = 8
        }else if month == 10 && day >= 23 || month == 11 && day <= 22 {
            //天蠍座
            constellationNumber = 9
        }else if month == 11 && day >= 23 || month == 12 && day <= 22 {
            //射手座
            constellationNumber = 10
        }else{
            //摩羯座
            constellationNumber = 11
        }

處理年紀：抓取選擇的欄位及現在時間，去做加減動作

let today = Date()
        let nowComponents = Calendar.current.dateComponents(in: TimeZone.current, from: today)
        let nowYear = nowComponents.year!
        var age = nowYear - year //年紀
        //年紀小於0，顯示0
        if age < 0 {
            age = 0
        }

處理生肖：(選擇的年份-4 )% 12 的值 就是陣列內的第n筆

//處理生肖
        let animalNumber = (year - 4) % 12 // (選的年份-4) % 12 取餘數 = 陣列第幾筆
        //更換資訊
        changeFile(constellationNumber: constellationNumber, animalNumber: animalNumber,age: age)
        var passwd : Int  = getPasswd()
        passwdLabel.text = "\(passwd)"
        passwdStatusLabel.text = passwdStatusMessage[passwd]
