实例方法
shuffled(using:)
返回序列的元素,使用给定的生成器作为随机源进行混洗。
声明
func shuffled<T>(using generator: inout T) -> [Self.Element] where T : RandomNumberGenerator
返回值
此序列的元素按打乱顺序排列的数组。
参数
generator
改组序列时使用的随机数生成器。
详述
当您使用自定义随机数生成器时,您可以使用此方法随机化序列的元素。例如,您可以通过在该范围内调用 shuffled(using:)
方法来打乱 0
和 9
之间的数字:
let numbers = 0...9
let shuffledNumbers = numbers.shuffled(using: &myGenerator)
// shuffledNumbers == [8, 9, 4, 3, 2, 6, 7, 0, 5, 1]
