用```替换NSString的替换为'\``

Question

我有一个NSString,我试图替换特殊字符.我的部分字符串如下所示:

我已经取代'了\'

Answer 1

如果您想更换'与\'使用

NSString *str = @"ladies'";
str = [str stringByReplacingOccurrencesOfString:@"'" withString:@"\\'"];

\ 是一个转义字符,所以你必须使用它两次.

Answer 2

注意: \是目标c中的转义字符.

 NSString *s = @"This is Testing Mode and we are testing just Details of this Ladies' Market place";


NSString *r = [s stringByReplacingOccurrencesOfString:@"'" withString:@"\\'"];
