I’m seeing this too, very annoying. My first reaction is that DZNEmptyDataSet is conflicting with iOS 11’s safe area and the issue presents itself when you migrate a VC’s storyboard to using safe areas.

I can't set the vertical offset in code, as even though it will be aligned correctly at first, once an item is added and removed, the empty data set view will once be aligned incorrectly,
Following is my configuration. self.collectionView.emptyDataSetSource and self.collectionView.emptyDataSetDelegate are set in viewDidLoad.
(NSAttributedString )titleForEmptyDataSet:(UIScrollView )scrollView {
NSDictionary *attributes = @{NSFontAttributeName:[UIFont systemFontOfSize:24.0f], NSForegroundColorAttributeName:[UIColor grayColor]};
return [[NSAttributedString alloc] initWithString:@"(redacted)" attributes:attributes]; }
(NSAttributedString )descriptionForEmptyDataSet:(UIScrollView )scrollView {
NSMutableParagraphStyle *paragraph = [NSMutableParagraphStyle new]; paragraph.lineBreakMode = NSLineBreakByWordWrapping; paragraph.alignment = NSTextAlignmentCenter;
NSDictionary attributes = @{NSFontAttributeName: [UIFont systemFontOfSize:14.0f], NSForegroundColorAttributeName:[UIColor grayColor], NSParagraphStyleAttributeName:paragraph}; NSString text = @"(redacted)";
return [[NSAttributedString alloc] initWithString:text attributes:attributes]; }
(UIImage )imageForEmptyDataSet:(UIScrollView )scrollView { return [UIImage imageNamed:@"(redacted)"]; } — You are receiving this because you are subscribed to this thread.

I am definitely using Safe Areas, so that might indeed be the problem. I am confused, however, about why it would work once an item is in the table or collection view and is then deleted. Are you seeing that too, @Dysonapps ?
Seeing exactly the same. The docs say something about safe area guides being non-0 only after views are loaded so layout is possibly being done too early in the view lifecycle?
This library definitely doesn’t seem to be safe area ready.
I just made my own simple empty set view that I set manually. Hopefully this repo can be taken over at some point and actively maintained, it was awesome!
I'm having the same issue. Any suggestions on how to fix vertical alignment?
I am using DZNEmptyDataSet on UITableViews and UICollectionViews throughout my application running iOS 11.1.

self.collectionView.emptyDataSetSource
andself.collectionView.emptyDataSetDelegate
are set inviewDidLoad
.Is there anything else I should include?
Thank you for any help anyone can provide!
