如何在Swift中合並兩個數組

Question

我有兩個數組。

let A = ["91","91","49"]
let B = ["9989898909","9089890890","9098979896"]

我需要合並這些數組並在下拉列表中顯示它

["91 9989898909","91 9089890890","49 9098979896"]

我如何使用swift得到這個結果。我是swift的新手，任何人都可以幫忙解決這個問題。

Answer 1

壓縮數組並連接結果：

let A=["91","91","49"]
let B=["9989898909","9089890890","9098979896"]
let zipped = zip(A, B)
let result = zipped.map { $0.0 + " " + $0.1 }

Answer 2

這是Swift中的一個片段：

let a = ["90", "91", "92"]
let b = ["80012", "82379", "123712"]

let result: [String] = a.enumerated().map { (index, element) in
    return index < b.count ? element + " " + b[index] : element
}

Answer 3

let A = ["91","91","49", "5"]
let B = ["9989898909","9089890890","9098979896"]

使用zip()連接數組A和B 。 如果A和B具有不同數量的元素，則加入仍然有效。 然后將壓縮結果數組中的元組map到它們之間有空格的元素

let C : [String] = zip(A,B).map {$0 + " " + $1}
