新Swiftで行こう…第３６回「ババ抜き５」　田部井保

目次　解説編

　さて、今回、今まであまりにも放置していた、ボタンの表示を何とかします。

　「配布」ボタンと「ペア削除」ボタンにしました。また、StyleをFilledにしました。ボタンを選んで、一番右の上のアイコン、左から５番目を押すとボタンの形状を色々変更できます。

　次にユーザーが４組のどれを選ぶかのボタンを付けます。

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.
        put53()
    }

    var eachCard: [[UILabel]] = [[],[],[],[]]
    var eachButton: [UIButton] = []
    var cardObj:Card = Card(cdCnt: Card.EnumCard.joker)
    func put53() {
        for i in 0 ..< 4 {
            for j in 0 ..< 14 {
                let lbl = UILabel(frame: CGRectMake(0, 0, 50, 21))
                lbl.center = CGPointMake(50 + 40 * CGFloat(j % 7), 150 + 120 * CGFloat(i) +
                                         50 * CGFloat(j / 7))
                lbl.textAlignment = NSTextAlignment.center
                if i != 0 && j == 13 {

                if (eachCard[i][j].tag == 52) || (eachCard[i][j].tag == -1) {
                    continue
                }

                        eachCard[i][k].tag = -1
                        break
                    }

            var k = 0
            for j in 0 ..< 14 {
                if eachCard[i][j].tag == -1 {
                    find = true
                } else {
                    if find {
                        eachCard[i][k].tag = eachCard[i][j].tag
                        eachCard[i][j].tag = -1
                    }
                    k += 1
                }
            }
            //for j in 0 ..< 14 {
            //    if eachCard[i][j].tag >= 0 {
            //        eachCard[i][j].text = cardObj.disp(card: eachCard[i][j].tag)
            //    } else {
            //        eachCard[i][j].text = "　"
            //    }
            //}
        }
        show()
    }
}

　次回は、ペア削除ボタンを押したら、選択変更出来ないようにします。
