[Rashesh-Bosamiya]

I want to reload particular cell & even its attached expandable view.

How can I do this?

Hello @Rashesh-Bosamiya,
Is there any problem when you use reloadData function?

[Rashesh-Bosamiya]

Actually I am using this library for showing filter options.

I have 7 different filters in each cell. Each filter has option to choose, when user choose any option from any cell's attached view, I have to reload whole tableView to highlight selected option.

Here is the problem, where I reload the whole tableView. It causes too much of dwindled performance.

So it's better to reload particular cell which needs refresh.

Hello @Rashesh-Bosamiya,
Maybe you can beginUpdate and reloadRowsAtIndexPaths and endUpdate
Is it helpful for you?

[Rashesh-Bosamiya]

I have tried reloadRowsAtIndexPaths, but this reload only cell(s) not attached UIView's.

But not with beginUpdate & endUpdate.

I'll try with beginUpdate & endUpdate & inform you.

But you got my problem right?

Sure. I fully understand what you mean. If you can't do this, I will try in this weekend.
Cheers!

My suggestion.

Can we have a method like tableView.expandCell(at indexPath:IndexPath)? or tableView.refreshCell(at indexPath:IndexPath)

That expand or refresh particular cell programmatically. informally we can achieve our goal to reload particular cell and its attached expandable view as well.

self.tableView.expandAll() kind of similar to this function.

Finally, I found out!

I just need to call reloadRowsAtIndexPaths.

The problem was:

I was passing incorrect indexPath in reloadRowsAtIndexPaths function.

I have return 6 in numberOfRowsInSection method.

Now, this library internally makes double numberOfRowsInSection as addition to expandable element.

Now if I want to reload 6th row, I just need to call tableView.reloadRows(at: [IndexPath(row: 6, section: 0)], with: .automatic)

By the way Thanks for you efforts and Interest.

Great! Thank you for contributing this library :)
