IOS - 删除所有＆＃39; \＆＃39;来自字典

Question

我已将所有值存储在字符串中，之后

NSMutableDictionary *dict=[[NSMutableDictionary alloc]init];
        [dict setValue:@"10004" forKey:@"acid"];
        [dict setValue:cleanedString forKey:@"registration-info"];

但是当我们打印时： -

{
        acid = 10004;
        "registration-info" = "[{\"q9\":\"AB\",\"q16\":\"ABC\",\"q1\":\"AB\",\"q20\":\"ABCD\",\"q2\":\"Thinking, Watching T.V.\",\"q12\":\"AB\",\"q17\":\"AB\",\"q3\":\"Job, Money, Family.\",\"q21\":\"c, Number of days: 20\",\"q13\":\"ABCD\",\"q4\":\"Job, Money..\",\"q18\":\"AB\",\"q5\":\"Job, Money, Family..\",\"q14\":\"Earning More Money\",\"email\":\"U10022@satanclause.it\",\"q6\":\"A\",\"q19\":\"AB\",\"q10\":\"Poorness..\",\"q7\":\"Thinking, \",\"q15\":\"Poorness..\",\"password\":\"Please write a password\",\"q8\":\"AB\",\"q11\":\"Loss..\"}]";
    }

我想在这本词典中删除所有\。任何人都可以帮助我..
