iOS如何在0索引的数组中添加对象并在tableview单元格中显示？

我有一个问题，一个数组有三个主要对象，我想在每个数组的0索引上添加一个对象

这是

在三个部分中，住宅区和商业区，我想在每个部分中添加所有住宅，所有地块和所有商业区，并在每个部分中添加它们的结果，即在每个部分的顶部添加所有住宅，所有地块和所有商业区

   - (void) loadFromDictionary:(NSDictionary *)theDictionary{
    _parent_id = -1;
    _type_id = [[theDictionary objectForKey:@"type_id"] intValue];
    _title = [[NSString alloc] initWithString:[theDictionary objectForKey:@"title"]];
    _title_alt1 = [[NSString alloc] initWithString:[theDictionary objectForKey:@"title_alt1"]];
    _title_alt2 = [[NSString alloc] initWithString:[theDictionary objectForKey:@"title_alt2"]];

    if([theDictionary objectForKey:@"parent_id"])
        _parent_id = [[theDictionary objectForKey:@"parent_id"] intValue];

    if([theDictionary objectForKey:@"child_list"])
        _child_list = [[NSMutableArray alloc] initWithArray:[[theDictionary objectForKey:@"child_list"] componentsSeparatedByString:@","]];

不完全确定你有什么问题。如果您只是想将对象插入数组和特定索引，您可以执行以下操作：

[searchTypes insertObject: addObject:newType atIndex:0];

我对上面的方法进行了如下更改：[typesDictionariesArray-insertObject:dict atIndex:[typesDictionariesArray count]-1]；该代码以计数分钟1插入对象。。它不是0，如果在添加第一个对象时数组为0，它实际上会崩溃。使用-1它不会崩溃，但在第一节中添加所有住宅和第二个索引，在第二节中添加所有地块也在第二个索引中添加，但在第三节中在第一个索引中添加所有商业
