實例方法
shuffled(using:)
返回序列的元素,使用給定的生成器作為隨機源進行混洗。
聲明
func shuffled<T>(using generator: inout T) -> [Self.Element] where T : RandomNumberGenerator
返回值
此序列的元素按打亂順序排列的數組。
參數
generator
改組序列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序列的元素。例如,您可以通過在該範圍內調用 shuffled(using:)
方法來打亂 0
和 9
之間的數字:
let numbers = 0...9
let shuffledNumbers = numbers.shuffled(using: &myGenerator)
// shuffledNumbers == [8, 9, 4, 3, 2, 6, 7, 0, 5, 1]
