fix false origin y of emptyDataSet view when scrollview had been scrolled

[benrudhart]

after scrolling a tableView and re-showing the emptyDataSet the offset (within a tableView) won't be fixed but adjusted to the scrollView's Y contentOffset.
This PR fixes this.

Hi!

I'm having the same issue and this PR fixes it. So +1 for merge.

P.S.
However, if I use tableView.reloadSections (with animation) instead of the tableView.reloadData the placeholder animates from the top to center. It's not a big deal, since it only happens when the user scrolled down before, however, do you have any idea how to fix this too?

@marcelmika: maybe we can add the view and adjust the frame inside of a performWithoutAnimation: method.

@dzenbot Anything preventing this PR getting merge?

Just tested it and it fixed the issue for me.

Thanks for your time 🍺

[benrudhart]

@dzenbot is there anything preventing this PR from being merged?

[dzenbot]

@benrudhart: I was mostly concerned about #182 (comment)
But maybe we can tackle that in a different PR?

[allaire]

@dzenbot Yes, since it's minor, we could tackle this in a different PR, absolutely.

Cheers!

vote for merge +1.

For people who has the same issue, there is a way to walk around it by calling self.tableView.setContentOffset(CGPointZero, animated:false) before reload the tableView. This will scroll to the top of the tableView, hence prevent the EmptyDataSet being off the screen

[rinat-enikeev]

Other possible solution:
in Delegate:

• (void)emptyDataSetWillAppear:(UIScrollView *)scrollView {
  [self.tableView setContentOffset:CGPointMake(0, -self.tableView.contentInset.top)];
  }
