下面的方法将转换您的原根字典的格式你想

- (NSDictionary *)reformatedDictionary:(NSDictionary *)rootDictionary 
{ 
    NSDictionary *list = rootDictionary[@"list"]; 

    NSMutableDictionary *bookmarksDict = [NSMutableDictionary dictionary]; 
    for (NSDictionary *dict in list) 
    { 
     NSString *bookId = dict[@"bookid"]; 
     NSArray *sectionItems = dict[@"sectionid"]; 
     for (NSString *string in sectionItems) 
     { 
      NSMutableArray *array = [bookmarksDict[string] mutableCopy]; 
      if (!array) { 
       array = [NSMutableArray array]; 
      } 
      [array addObject:bookId]; 
      [bookmarksDict setObject:array forKey:string]; 
     } 

    } 
    return @{@"sectionlist":bookmarksDict}; 
}
