iOS Adjusting Collections View to ImageView (Width & Height)

[loon3y]

whats the best solution to have my collections view adjust to the size of my image view,

since photos taken in portrait orientation is longer than when taken in landscape, my image view size is going to vary by screen orientation.


like so:

Ray Wenderlich's Tutorial on UICollectionView

#pragma mark – UICollectionViewDelegateFlowLayout
 
// 1
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    NSString *searchTerm = self.searches[indexPath.section]; FlickrPhoto *photo =
    self.searchResults[searchTerm][indexPath.row];
    // 2
    CGSize retval = photo.thumbnail.size.width > 0 ? photo.thumbnail.size : CGSizeMake(100, 100);
    retval.height += 35; retval.width += 35; return retval;
}
 
// 3
- (UIEdgeInsets)collectionView:
(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
    return UIEdgeInsetsMake(50, 20, 50, 20); 
}

He has custom objects that represent photos and they have a thumbnail property but you should just be able to use the size of your UIImage
