新Swiftで行こう…第１８回「ポーカー３」 田部井保
前回の問題は、カードを何枚か捨てて、再配布するというものでした。
さて、前回の問題の答えです。

}
eachCard[i].text = strCard
eachCard[i].tag = card
}
}
@IBAction func btnReTouch(_ sender: Any) {

}

count -= 1
var strCard: String
if card == 52 {

} else {

}
eachCard[i].text = strCard
eachCard[i].tag = card
eachButton[i].setTitle("off", for: .normal)
}
}
}
}最初に配る部分と、追加で配る部分で大分重複があります。これを一つにまとめます。まとめておくと後で修正が楽になります。

let mark: [String] = ["♣️","♦️","❤️","♠️"]
let number: [String] = ["A","2","3","4","5","6","7","8","9","T","J","Q","K"]
enum EnumCard {
static let Count = 52
}
var check: [Bool] = [Bool](repeating: false, count: EnumCard.Count)
var count = EnumCard.Count
var eachCard: [UILabel] = []
var eachButton: [UIButton] = []
func put(i: Int) {
var card = 0
let randInt = Int.random(in: 0 ..< count)
for i in 0 ... randInt {
while check[card] {
card += 1
}
if i < randInt {

}
}
check[card] = true

eachCard[i].tag = card
}
@IBAction func btnGoTouch(_ sender: Any) {
for i in 0 ..< EnumCard.Count {
check[i] = false
}
count = EnumCard.Count
for i in 0 ..< 5 {
put(i: i)
}
}
@IBAction func btnReTouch(_ sender: Any) {
for i in 0 ..< 5 {
if eachButton[i].currentTitle == "on" {
put(i: i)
eachButton[i].setTitle("off", for: .normal)
}
}
}
}同じ処理をまとめるとすっきりしますね。
さて次回からは、ポーカーの役の判別に入って行きます。まずは簡単な所から、フラッシュを判別する処理を作ってみて下さい。フラッシュとは、5枚とも同じマークになる形です。
