Awesome!!

I am now struggling with this but where I have custom cell in each table. I can't initialise the cell as UITableViewCell and then down cast as two different cell classes, or can i?

need to beware those force unwraps...

thank you!

simple and effective.

thanks got idea how to do it

This is great! How would it work with custom cells?

what kind of identifier I can use if I like to use the 'didSelectRowAt indexPath' method for both table views?

Good example thanks!

Nice Brother!

Nice

Great !

One can use tags to efficiently compare one table view from the other. ie ``tableview.tag == self.tableView.tag`

nice example but i have issue on didSelectRowAt indexPath. I have two table view .First one is for displaying list and other is for displaying spinner in header view of first table view. When i implement didSelectRowAt indexPath it always return outer table view index path not index path of spinner table view from header view . thank you

Thanks.very helpful

Thanks for the code - was wondering how to do this.

Here's a repo with a demo project above: https://github.com/infiniteloopltd/two-tableviews

Thanks for your code. It helped me a lot :)

Thank you. I wish the protocol implementation didn't work like this, I'd rather have one cellForRowAtIndexPath per TableView ):

@TheikChan, are you wanting to print the value of each table view, not just the first?

You saved my life

I would strongly discourage making your main tableview-owning ViewController conform to UITableViewDataSource and UITableViewDelegate like this, if you want to drive multiple tables.

The fact that you have branching logic in your data source methods like if tableView == self.tableView { is an indication that you have two conjoined twin objects that are trying to get out.

Make two separate data source objects, and let them each focus on one of the two data sets, without any branching like this.
