scrolling hangs with more then 50 records

I also noticed that. This is a great library but unfortunately it is working really slow when there is about 100 rows in the table view.

Hey,
Thanks for the report. I will look into this problem. Are you sure you not perform any time consuming operations in methods of the RATreeView's data source or delegate?

Hi. I also had the same problem and figured out it's reason. Each time your treeView wants to display a row, it asks RATreeNodeController for it's index. This object calculates it's index based on all previous RATreeNodeController indexes in hierarchy. So the more cells (RATreeNodeControllers) you display the more lags you have. I made a simple workaround in my fork and you can use that. What I have done is caching of RATreeNodeController's indexes.

Hi, I tried your workaround @vbrylinskiy as I had a row to expand with 326 children which was hanging the main queue for almost 10 secs. With your workaround it takes it now takes less than 1 sec. Thanks!

Now RATreeView works smoothly in my project. To expand or scrolling hangs won't happen again. @vbrylinskiy thanks!

Is this now merged with the same branch?

[leszek-s]

I've created a pull request with this fix some time ago but it is still waiting for acceptance.

[vlad-brylinski]

I don't think that my workaround should be merged into the main repo. The focus should be made on fixing the architecture.

[Augustyniak]

Today version 1.0.0 was released. It should fix performance issues. There are also some additional changes (described in release notes).

I hope it will help.
Closing issue. Feel free to reopen if necessary.

Hello, I now have 50000 records, each time you expand and merge nodes are very slow, how to solve?（你好，我现在有50000条记录，每次展开和合并节点的时候都很慢，请问怎么能解决？）

@implementation RATreeView (TableViewDataSource)

• (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
  {
  return 1;
  }
  how can i change this method ,i want return more section?

[MrNAVY]

要展开多个section 怎么做呢？所有的页面都连着在一起，要分开一些section 好像做不到
