swift - 从 swift 字符串中删除时间戳

Question

我正在创建一个应用程序，从给定的巨大多行字符串中删除新行和时间戳。我设法使用 string.replacingOccurences(of:_, by:_) 删除了新行，但找不到摆脱时间戳的方法。这是示例字符串的片段:

Answer 1

尝试以下代码仅从字符串中删除时间戳。

(时间戳只能采用此格式。如果格式更改，可能会出现问题。)

let string = "6:42enjoyed and if you haven't already what"
let result = string.trimmingCharacters(in: CharacterSet(charactersIn: "01234567890:"))
print(result)

控制台打印:-
