it is caused by EWBlurPresentSegue. looks like the collectionView's - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath is not being called correctly.

assigning to @callzhang for furthur investigation.

Some investigation: Normally, the content size should be positive: However, the content size should is 0:

Fixed temporarily

@callzhang what's the tmp fix? use non-blur?

contentSize is 0 is normal when using autolayout with scrollview.

I used KVO to correct the offset. Is it related to top LayoutGuide?

[caoer]

@callzhang I'd like to look at the code. can you attach the SHA here? suggest to put SHA if any for all issues for the sake of tracking progress.

EWPeopleArrayChildViewController.m

[self.KVOController observe:self.collectionView keyPath:@"contentInset" options:NSKeyValueObservingOptionNew block:^(id observer, id object, NSDictionary *change) { DDLogInfo(@"Collection view insert changed to %@", NSStringFromUIEdgeInsets(self.collectionView.contentInset)); if (_collectionView.contentInset.top != 0) { UIEdgeInsets insert = self.collectionView.contentInset; insert.top = 0; self.collectionView.contentInset = insert; } }];

ah. interesting fix!!! thanks. I will look into this. don't close this issue yet.

[callzhang]

I used Reveal, it's a good tool in debugging UI issues.

It could be related to topLayoutGuide?
