推荐答案
假设您的字符串实际上具有文字字符 \
, u
, 0
> 等,你需要这样做:
Assuming your string actually has the literal characters \
, u
, 0
, etc., you need to do this:
[mutstr_Description replaceOccurrencesOfString:@"\\u00e2\\u0080\\u0099" withString:@"'" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [mutstr_Description length])];
您需要转义反斜杠.
更新 - 也许您的字符串实际上具有那些控制字符.试试这个:
Update - perhaps your string actually has those control characters. Try this:
NSString *controlChars = [NSString stringWithFormat:@"%C%C%C", 0xe2, 0x80, 0x99];
[mutstr_Description replaceOccurrencesOfString:controlChars withString:@"'" options:NSLiteralSearch range:NSMakeRange(0, [mutstr_Description length])];
