How do I hook up UICollectionViewController in UIContainerView
ios, uicollectionview
Solution
Create a uiviewcontroller class to manage the bottom container. Link as you normally would using that view controller. Connect delegate, datasource, implement the delegate and data source... etc...
Problem
I have an app that looks like this: `ViewController` is the parent VC into which I placed 3 container view controllers. I subclassed `UIViewController` for all three, Top, Mid & BottomContainerViewControllers. Here is my question. I want the `BottomVC` to have a `UICollectionView` which scrolls sideways. So I added a `UICollectionView` as you can see (gave it a nice greenish background). But my question is, how do I hook this up? This is my BottomContainerViewController.h: ``` #import <UIKit/UIKit.h> @interface BottomContainerViewController : UICollectionViewController <UICollectionViewDataSource, UICollectionViewDelegate> @property (nonatomic, retain) IBOutlet UICollectionView *collectionView; @end ``` And the .m file has the following methods: ``` - (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath ``` But when I run it I get: ``` [UICollectionViewController loadView] loaded the "qcP-Hl-Txn-view-aJq-Dc-875" nib but didn't get a UICollectionView.' ``` The `UICollectionView` outlet is connected. What else could be the problem?
