expandDefaultRowForItem

[Gusont]

I have a need.add a Default Row. This realization Code,

• (void)searchModelWith:(NSArray<OrganizationModel *> *)models{
  [models enumerateObjectsUsingBlock:^(OrganizationModel * _Nonnull model, NSUInteger idx, BOOL * _Nonnull stop) {
  if ([model.key isEqualToString:[GlobalCurrencyInfo SharedInstance].userInfoModel.departMentId]) {
  [self.treeViewexpandRowIndex addObject:@(idx)];
  [self searchChildrenindex:models datas:self.organizationArr];
  {///expandTreeView
  __block NSArray *marr = self.organizationArr;
  [[[self.treeViewexpandRowIndex reverseObjectEnumerator] allObjects] enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
  OrganizationModel *item = marr[[obj integerValue]];
  item.isOpen = YES;
  [self.treeView expandRowForItem:item];
  [self.treeView reloadRowsForItems:@[item] withRowAnimation:RATreeViewRowAnimationNone];
  marr = item.children;
  }];
  model.isOpen = NO;
  [self treeView:self.treeView didSelectRowForItem:model];
  }
  return;
  }
  if (model.children.count) {
  [self searchModelWith:model.children];
  }

  }];
  }

• (void)searchChildrenindex:(NSArray *)childerns datas:(NSArray *)datas{

  [datas enumerateObjectsUsingBlock:^(OrganizationModel * _Nonnull model, NSUInteger idx, BOOL * _Nonnull stop) {
  if (model.children == childerns) {
  [self.treeViewexpandRowIndex addObject: @(idx)];
  [self searchChildrenindex:datas datas:self.organizationArr];
  }
  if (model.children.count) {
  [self searchChildrenindex:childerns datas:model.children];
  }
  }];

}
