过滤字符串数组，包括“like"状况

本文介绍了过滤字符串数组，包括“like"状况的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

如果我的主数组是 ["Hello","Bye","Halo"]，并且我正在搜索 "lo"，它将过滤数组仅用于["Hello", "Halo"].

If my main array is ["Hello","Bye","Halo"], and I'm searching for "lo", it will filter the array only to ["Hello", "Halo"].

这是我试过的:

let matchingTerms = filter(catalogNames) { $0.rangeOfString(self.txtField.text!, options: .CaseInsensitiveSearch) != nil }

它抛出

Type of expression is ambiguous without more context

有什么建议吗?

推荐答案

使用 contains 代替:

let arr = ["Hello","Bye","Halo"] let filtered = arr.filter { $0.contains("lo") } print(filtered)

输出

["你好", "光环"]

["Hello", "Halo"]

感谢@user3441734 指出该功能当然只有在您import Foundation

Thanks to @user3441734 for pointing out that functionality is of course only available when you import Foundation
