由 孤街醉人 提交于 2019-12-10 09:36:06

问题 I have an input string that looks something like this: HLI6Ch60000Ch500C0Ch46400Ch30000Ch21888Ch10E79CS07LCU3Ch37880Ch27800Ch16480CS8CA00000000000000000000 Now I don't care about the part that follows the last letter A , it'll always be A and exactly 20 numbers that are of no use to me.

问题 I looked into the Apple reference on NSRegularExpression , and understand that in order see if the string is Cyrillic I should use \p{script=cyrillic} . However, I have not been able to find an actual example of how this is done in the reference guide or in an answer located in SO.
