Make UICollectionView zoomable?
ios, ios6, uicollectionview
Solution
I think what you're asking for looks like what is done in the `WWDC1012` video entitled Advanced Collection Views and Building Custom Layouts (demo starts at 20:20).
You basically have to add `pinchGesture` to you `UICollectionView`, then pass the `pinch properties` (scale, center) to the `UICollectionViewLayout` (which is a `subclass` of `UICollectionViewFlowLayout`), your layout will then perform the `transformations` needed to `zoom` on the desired cell.
Problem
Is there any method make the `UICollectionView` `zoomable`, i.e. when you pinch, all the cells can be zoomed in and out. I can implement this in `UIScrollView` by returning the only `subview` of the `UIScrollView` from `delegate` method ``` - (UIView*)viewForZoomingInScrollView:(UIScrollView *)scrollView ``` Since `UICollectionView` is kind of `UIScrollView`, is there a way or work around to implement this? Does the `UICollectionView` has one direct subview that contains all cells? Thanks
