實例方法
all
allSatisfy(_:)
返回一個布爾值,指示序列的每個元素是否滿足給定的謂詞。
聲明
func allSatisfy(_ predicate: (Self.Element) throws -> Bool) rethrows -> Bool
返回值
true
如果序列僅包含滿足 predicate
的元素;否則,false
。
參數
predicate
一個閉包,它將序列的一個元素作為其參數並返回一個布爾值,該值指示傳遞的元素是否滿足條件。
詳述
以下代碼使用此方法測試數組中的所有名稱是否至少包含五個字符:
let names = ["Sofia", "Camilla", "Martina", "Mateo", "Nicolás"]
let allHaveAtLeastFive = names.allSatisfy({ $0.count >= 5 })
// allHaveAtLeastFive == true
如果序列為空,則此方法返回 true
。
