UICollectionViewCell Border / Shadow

Question

When building an iPad App, how can you draw a border around a UICollectionViewCell?

More details: I implemented a class ProductCell which extends UICollectionViewCell. Now, I would like to assign some fancy details, e.g. a border, shadow, etc. However, when trying to use something like this here, Xcode tells me that the receiver type 'CALayer' is a forward declaration.

Just for a bit more implementation:

#import <QuartzCore/QuartzCore.h> 

in your.m

Make sure your class implements

- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath;  

as this is where the cell is setup.

You can then change cell.layer.background (only available once quartz is imported)

See below

- (UICollectionViewCell *)collectionView:(UICollectionView *)cv cellForItemAtIndexPath:(NSIndexPath *)indexPath {     MyCollectionViewCell *cell = [cv dequeueReusableCellWithReuseIdentifier:@"pressieCell" forIndexPath:indexPath];     //other cell setup here      cell.layer.borderWidth=1.0f;     cell.layer.borderColor=[UIColor blueColor].CGColor;      return cell; }
