Question

my first time creating a UIControlerView and it seems that the delegates are never activated. Please tell me where I am going wrong.

Thank you!
By the way I created the IBOutlet by dragging from the storyboard…

.h

#import <UIKit/UIKit.h>

@interface CollectionController : UIViewController<UICollectionViewDelegate,UICollectionViewDataSource>

@property (weak, nonatomic) IBOutlet UICollectionView *controllerTableView;

@end

.m

#import "CollectionController.h"
#import "CollectionVIewCell.h"

@interface CollectionController ()

@end

@implementation CollectionController

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[self controllerTableView]setDelegate:self];
    [[self controllerTableView]setDataSource:self];
    // Do any additional setup after loading the view.
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section{
    return 10;
}

-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView{
    return 1;
}


-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier=@"Cell";
    CollectionVIewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];

    cell.labelDisplay.text=@"hi";
    //set up data in images

    return cell;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

Try hooking up your UICollectionView‘s delegate and data source in the xib rather than in code.
