HW11: 骰子比大小之搶紅包遊戲

來和 Peter 搶紅包啦!!

遊戲敘述:
由 Peter 這裡提供紅包 2000 元和一位同學搶紅包
>>兩人各自有三顆骰子，比較雙方點數總合
>>兩人各自初始為 0 元，勝方依據壓注的金額增加紅包總額
>>搶完後若不滿意 Peter 搶回得紅包金額可以按重新開始
>>可決定壓注的金額 100/500/all in
>>用 alert 顯示結果: 紅包還沒搶光時，alert 將顯示 ok & 再玩一次的按鈕，搶光後顯示紅包沒了
>>金額小於賭注時會自動all in

＊for 迴圈
＊outlet collection
＊present alert controller

Storyboard design

DiceViewController(UIViewController)

storyboard

Swift function

peter 的三顆骰子為 outlet collection: cpuDiceImageView: [UIImageView]!
學生的三顆骰子為 outlet collection: playerDiceImageView: [UIImageView]!

[Code 流程]: 
1. 參數初始: restart in viewDidLoad()
2. 點擊 Play Button -> IBAction func play: playGame
3. playGame: 
   當剩餘紅包錢小於賭金時 playGame 會自動 all in
   random 骰子(for loop & random)
   比較完大小後顯示 alert(present alert)
   依據選擇的紅包數更新數值
   當 playGame 後的剩餘紅包錢若為 0, play button 變為重新再來
4. 點擊重新再來 -> IBAction func play: restart
