问题描述
我正在尝试用 \: 替换出现的 : 但我收到 文本中的转义序列无效 错误.我试过用 \\\: 转义，但它用双杠替换了出现:
I'm trying to replace occurrences of : with \: but I'm getting the Invalid escape sequence in literal error.
I've tried escaping with \\\:, but it's replacing the occurrence with the double bar:
我需要:
2000:2018-07-25T10\:31\:06Z:2018-07-30
来自原始字符串:
2000:2018-07-25T10:31:06Z:2018-07-30
我得到:
2000:2018-07-25T10\\\:31\\\:06Z:2018-07-30
我的代码:
newString.replacingOccurrences(of: ":", with: "\:") //Invalid escape sequence in literal
newString.replacingOccurrences(of: ":", with: "\\:") //not quite want I need
推荐答案
您需要使用另一个反斜杠来转义反斜杠.所以如果你想用 "\:" 替换 ":" 你需要用 "\\:" 替换.
You need to escape backslashes with another backslash. So if you want to replace ":" with "\:"you need to replace with "\\:".
let backslashString = string.replacingOccurrences(of: ":", with: "\\:")
