iOS开发之将NSString字符串转换为字典NSDictionary

- (NSDictionary *)dictionaryWithJsonString:(NSString *)jsonString {

    if (jsonString == nil) {

        return nil;

    }

    

    NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

    NSError *err;

    NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData

                                                        options:NSJSONReadingMutableContainers

                                                          error:&err];

    if(err) {

        GCLog(@"json解析失败：%@",err);

        return nil;

    }

    return dic;

}
