This is an example of how to scaffold API endpoints to list / get / create / update / delete Posts in a Keystone website.

It's a modification of the default project created with the yo keystone generator (see https://github.com/JedWatson/generator-keystone)

Gists don't let you specify full paths, so in the project structure the files would be:

routes-index.js        -->    /routes/index.js         // modified to add the api endpoints
routes-api-posts.js    -->    /routes/api/posts.js     // new file containing the Post API route controllers

//Override UICollectionViewFlowLayout class
@interface FixedHeaderLayout : UICollectionViewFlowLayout

@implementation FixedHeaderLayout
//Override shouldInvalidateLayoutForBoundsChange to require a layout update when we scroll 
- (BOOL) shouldInvalidateLayoutForBoundsChange:(CGRect)newBounds {
    return YES;
