IOS Swift 2.0卡改组功能


IOS Swift 2.0 Card shuffling function

本问题已经有最佳答案，请猛点这里访问。

不，我正在尝试用52张牌的标准牌组创建一个纸牌游戏。这是我想制作成func的代码，所以我不必每次都手工写出来。我正在创建5个不同的玩家，以便将其复制到其他玩家。

func firstPlayerCardShuffle() {
var firstPlayerCard1Num = (Int(arc4random_uniform(UInt32(13)) + 2))
var firstPlayerCard1Suit = suits[Int(arc4random_uniform(UInt32(suits.count)))]
var firstPlayerCard1 ="\(firstPlayerCard1Num) of \(firstPlayerCard1Suit)"

var firstPlayerCard2Num = (Int(arc4random_uniform(UInt32(13)) + 2))
var firstPlayerCard2Suit = suits[Int(arc4random_uniform(UInt32(suits.count)))]
var firstPlayerCard2 ="\(firstPlayerCard2Num) of \(firstPlayerCard2Suit)"

return(firstPlayerCard1,firstPlayerCard2)
}

有人能告诉我我错过了什么吗？

// prints five random cards
