UITableView flicker

[aamahdwalker]

Experiencing bug on iPhoneX only. Cannot reproduce in simulator. When I let go of pull, the tableView quickly snaps to the top of the view and then readjusts to proper position under navigation bar.

@aamahdwalker I have the same issue. How did you fix it?

[ren6]

Okay, I fixed it like this. In DGElasticPullToRefreshView.swift inside displayLinkTick() method I changed this:

scrollView.contentInset.top = bounceAnimationHelperView.dg_center(isAnimating()).y
scrollView.contentOffset.y = -scrollView.contentInset.top

to this:

let oldValue = scrollView.contentInset.top
let newValue = bounceAnimationHelperView.dg_center(isAnimating()).y
if oldValue > newValue && oldValue > 0 && (newValue == 0 || newValue == DGElasticPullToRefreshConstants.LoadingContentInset) && oldValue - newValue > DGElasticPullToRefreshConstants.LoadingContentInset {
  print("SKIP STRANGE INSET CHANGING: from \(oldValue) to \(newValue)")
} else {
   scrollView.contentInset.top = newValue
   scrollView.contentOffset.y = -scrollView.contentInset.top
}

@ren6 Nice! Another fix is to add lines 301-302 in animation block like so..

  [UIView animateWithDuration:0.1 animations:^{
        scrollView.contentInset = contentInset;
    }
                     completion:^(BOOL finished) {
                         completionBlock();
                     }];
}
