UICollectionView and UICollectionViewCell not functioning - ios

Question

I'm trying to create my own custom UICollectionView
For starters, I added a CollectionView to my Storyboard.
The reason for the PURPLE is because at first I expereinced my contorller not showing at all. So I turned the CELL grey and noticed it was the item not visible after also turning the Collection View purple.
I'm trying to populate my collection view with a unique image and label. This is my beginning of the journey.
Here is my CollectionViewController
#import "LoadZoneViewController.h"
#import "ZoneCollectionViewCell.h"
#interface LoadZoneViewController ()
#end
#implementation LoadZoneViewController
static NSString * const reuseIdentifier = #"Cell";
- (void)viewDidLoad {
[super viewDidLoad];
// Register cell classes
[self.collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:reuseIdentifier];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark <UICollectionViewDataSource>
- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
#warning Incomplete implementation, return the number of sections
return 12;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
#warning Incomplete implementation, return the number of items
return 12;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:reuseIdentifier forIndexPath:indexPath];
// Configure the cell
return cell;
}
#pragma mark <UICollectionViewDelegate>
#end
I defined a custom UICollectionViewCell as well, but I thought I should worry about that after I fix this issue. The current issue is simply that the label doesn't appear, the View has a scrollbar to the bottom, but I'm not seeing 12 labels.

Try adding delegates to your class interface
#interface LoadZoneViewController ()<UICollectionViewDelegate,UICollectionViewDataSource>
Add this to your viewDidLoad
[CollView registerNib:[UINib nibWithNibName:#"ZoneCollectionViewCell" bundle:nil] forCellWithReuseIdentifier:#"YourCellIdentifier"];
And do this is in your cellForItemAtIndexPath
NSString *identifier = #"YourCellIdentifier";
ZoneCollectionViewCell *cell = (ZoneCollectionViewCell*)[collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
