如何使用swift检查字符串值是否在数组中[重复]

Question

我试过了：

var array = ["led","zepp","jimmy","page"]

if array.contains("jimmy") { // error : [String] does not have a member named 'contains' .
    print("yes")
}

[String] 类型数组的语法是什么？

Answer 1

取决于 1.2 中的 swift... 版本：

    var array = ["led","zepp","jimmy","page"]
    if find(array, "jimmy") != nil {
        println("yay")
    }

在 Swift 2 中

   var array = ["led","zepp","jimmy","page"]
    if array.indexOf("jimmy") != nil {
        print("yay")
    }
