删除字符串中的特定子字符串[Swift]

Question

我有一个字符串var m = "I random don't like confusing random code."我想删除字符串random中子字符串m的所有实例，返回字符串parsed并删除已完成。

最终结果是：parsed = "I don't like confusing code."

我如何在Swift 3.0 +中执行此操作？

Answer 1

这很简单，有很多方法可以用空字符串替换字符串“random”

let parsed = m.replacingOccurrences(of: "random", with: "")

Answer 2

取决于您希望替换的复杂程度（在random之后删除/保留标点符号）。如果您想删除random以及可选的隐藏空间：

var m = "I random don't like confusing random code."
m = m.replacingOccurrences(of: "random ?", with: "", options: [.caseInsensitive, .regularExpression])
