實例方法
shuffle(using:)
使用給定的生成器作為隨機源,對集合進行Shuffle[洗牌]。
聲明
mutating func shuffle<T>(using generator: inout T) where T : RandomNumberGenerator
當
Self
符合 RandomAccessCollection
時可用。參數
generator
改組集合時使用的隨機數生成器。
詳述
當您使用自定義隨機數生成器時,您可以使用此方法隨機化集合的元素。例如,您可以使用shuffle(using:)
方法對數組元素進行隨機重新排序。
var names = ["Alejandro", "Camila", "Diego", "Luciana", "Luis", "Sofía"]
names.shuffle(using: &myGenerator)
// names == ["Sofía", "Alejandro", "Camila", "Luis", "Diego", "Luciana"]
