Swiftで行こう…第１８回「ポーカー５」（もちゃち）

ーーーMavericks Xcode6.1ーーー
前回の問題は、ペアを判別するという事でした。
前回の問題の答の一つです。
以下ソースコードです。
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
for i in 0 ..< cardCount {
check += [false]
}
count = cardCount
for i in 0 ..< 5 {
var lbl = UILabel(frame: CGRectMake(0, 0, 50, 21))
lbl.center = CGPointMake(50 + 50 * CGFloat(i), 50)
lbl.textAlignment = NSTextAlignment.Center
lbl.text = "⬛️"
eachCard += [lbl]
self.view.addSubview(lbl)
let btn = UIButton(frame: CGRectMake(0, 0, 50, 21)) as UIButton
btn.center = CGPointMake(50 + 50 * CGFloat(i), 100)
btn.setTitle("off", forState: .Normal)
btn.setTitleColor(UIColor.blackColor(), forState: .Normal)
btn.addTarget(self, action: "btnTapped:", forControlEvents: .TouchUpInside)
btn.tag = i
eachButton += [btn]
self.view.addSubview(btn)
}
}
func btnTapped(sender: UIButton) {
if sender.currentTitle == "off" {
sender.setTitle("on", forState: .Normal)
eachCard[sender.tag].text = "⬛️"
} else {
sender.setTitle("off", forState: .Normal)
var card = eachCard[sender.tag].tag
var strCard: String
if card == 52 {
strCard = "JK"
} else {
strCard = mark[card / 13] + number[card % 13]
}
eachCard[sender.tag].text = strCard
}
}
let mark: [String] = ["♣️","♦️","♥️","♠️"]
let number: [String] = ["A","2","3","4","5","6","7","8","9","T","J","Q","K"]
let cardCount = 52
var check: [Bool] = []
var count = 0
var eachCard: [UILabel] = []
var eachButton: [UIButton] = []
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func put(i: Int) {
var card: Int = 0
var randInt = Int(arc4random_uniform(UInt32(count)))
for i in 0 ... randInt {
while check[card] {
card++
}
if i < randInt {
card++
}
}
check[card] = true
count--
var strCard: String
if card == 52 {
strCard = "JK"
} else {
strCard = mark[card / 13] + number[card % 13]
}
eachCard[i].text = strCard
eachCard[i].tag = card
}
func flush() {
var chk:Bool = true
var mark: Int = eachCard[0].tag / 13
for i in 1 ..< 5 {
if mark != eachCard[i].tag / 13 {
chk = false
break
}
}
if chk {
var alert = UIAlertView()
alert.title = "フラッシュ"
alert.message = "フラッシュです"
alert.addButtonWithTitle("OK")
alert.show()
} else {
var ck:Bool = false
for i in 0 ..< 5 {
for j in i + 1 ..< 5 {
if eachCard[i].tag % 13 == eachCard[j].tag % 13 {
ck = true
}
}
}
if ck {
var alert = UIAlertView()
alert.title = "ペア"
alert.message = "ペアがあります"
alert.addButtonWithTitle("OK")
alert.show()
}
}
}
@IBAction func btnGoTouch(sender: AnyObject) {
for i in 0 ..< cardCount {
check[i] = false
}
count = cardCount
for i in 0 ..< 5 {
put(i)
}
flush()
}
@IBAction func btnReTouch(sender: AnyObject) {
for i in 0 ..< 5 {
if eachButton[i].currentTitle == "on" {
put(i)
eachButton[i].setTitle("off", forState: .Normal)
}
}
flush()
}
}
さて、今回追加したペアの判定部分、
var ck:Bool = false
for i in 0 ..< 5 {
for j in i + 1 ..< 5 {
if eachCard[i].tag % 13 == eachCard[j].tag % 13 {
ck = true
}
}
}
if ck {
var alert = UIAlertView()
alert.title = "ペア"
alert.message = "ペアがあります"
alert.addButtonWithTitle("OK")
alert.show()
}
後半部分は、単にメッセージを出す部分なので、前半部分が肝となります。
カードを全パターン比較して、同じ番号のものがあるか判別しています。このコードを少し変更する事で、ワンペア、ツーペア、スリーカード、フルハウス、フォーカードの区別が出来ないでしょうか。
