一、概念

#pragma mark - 检测是否为合法密码

- (BOOL)isLegalPassword:(NSString *)psw {

    NSString *passWordRegex = @"^[\\w~\\!\\@\\#\\$\\%\\^\\&\\*\\?\\(\\)\\+\\-=\\[\\]\\{\\|`\\};:'\"\\,\\.\\/]{6,32}$";

    NSPredicate *passWordPredicate = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",passWordRegex];

    return [passWordPredicate evaluateWithObject:psw];

}

谢谢!!!
