Keeping the contentOffset in a UICollectionView while rotating Interface Orientation

Question

I\'m trying to handle interface orientation changes in a UICollectionViewController. What I\'m trying to achieve is, that I want to have the same contentOffset afte

Answer 1

My way is to use a UICollectionViewFlowlayout object.

Set the ojbect line spacing if it scrolls horizontally.

[flowLayout setMinimumLineSpacing:26.0f];

Set its interitem spacing if it scrolls vertically.

[flowLayout setMinimumInteritemSpacing:0.0f];

Notice it behaves different when you rotate the screen. In my case, I have it scrolls horizontally so minimumlinespacing is 26.0f. Then it seems horrible when it rotates to landscape direction. I have to check rotation and set minimumlinespacing for that direction 0.0f to make it right.

That's it! Simple.
