how to implement a zoom in/out animation for UICollectionView

Question

I got a UICollectionView with several cells on the screen.

I want to add one animation that can zoom out/in the cell;

The logic behind is when clicking the cell, it will invoke [self.navigationController pushViewController:_chartViewController animated:NO];

I am not clear how to zoom in/out the new _chartViewController

Looking for the APIs and some key takeaways for doing it. Thank in advance!

What you're looking for is called a Custom Segue Animation. In your example you click a cell and it zooms to another view controller.

You can find a good example here that uses a tableview instead of a collection view: https://github.com/visnup/tableview-open

This code employs a tableview - when a cell is clicked it "zooms" to the respective view controller that is associated with that cell.

I have added the following lines in to the viewDidLoad method of my UICollectionViewController:

[collectionView setMinimumZoomScale: 0.25];
[collectionView setMaximumZoomScale: 4];

zoom entire UICollectionView - It also has a link to Sample code for UICollectionView. You might be interested in checking it.
