UICollectionView not showing images from CameraImage - Objective C - objective-c

Question

Searched the forum and could not find a suitable answer that works. I suspect something is wrong with the code. I am taking pictures with a camera and trying to show them in a UICollectionView. The collectionView has a cell with a UIImageView inside of it.
Even when setting a static image and background colour I still don't see anything (not even the colour).
Code is as follows:
#import "CameraPageViewController.h"
#interface CameraPageViewController ()
#end
#implementation CameraPageViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
_imageList = [[NSMutableArray alloc] init];
_collectionView.delegate = self;
_collectionView.dataSource = self;
[_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:#"PictureCell"];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)takePhoto:(id)sender {
UIImagePickerController *imagePickController=[[UIImagePickerController alloc]init];
imagePickController.sourceType=UIImagePickerControllerSourceTypeCamera;
imagePickController.delegate=self;
imagePickController.allowsEditing=TRUE;
[self presentViewController:imagePickController animated:YES completion:nil];
}
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
UIImage *chosenImage = editingInfo[UIImagePickerControllerOriginalImage];
[_imageList addObject:chosenImage];
[self dismissViewControllerAnimated:YES completion:nil];
[_collectionView reloadData];
}
- (NSInteger)numberOfSectionsInCollectionView: (UICollectionView *)collectionView {
return 1;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
return [self.imageList count];
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = #"PictureCell";
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
UIImageView *pictureView = (UIImageView *) [cell viewWithTag:110];
NSInteger rowValue = indexPath.row;
UIImage *currentImage = [_imageList objectAtIndex:indexPath.row];
pictureView.image = currentImage;
return cell;
}
#end

i think u might missed the setting the layout for your collection view set it and try
- (void)viewDidLoad
{
[super viewDidLoad];
//...other code
_imageList = [[NSMutableArray alloc] init];
//set layout hear
UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init]; //default layout
[flowLayout setScrollDirection:UICollectionViewScrollDirectionVertical];
flowLayout.minimumInteritemSpacing = 0.0f;
flowLayout.minimumLineSpacing = 0.33f; //set the offset between items
_collectionView.showsHorizontalScrollIndicator = NO;
_collectionView.showsVerticalScrollIndicator = NO;
[_collectionView setCollectionViewLayout:flowLayout];
_collectionView.delegate = self;
_collectionView.dataSource = self;
[_collectionView registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:#"PictureCell"];
}
//implement this delegate method to return item size for each cell
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
return CGSizeMake(200.0f,300.0f);
}

Fixed it by adding the images as sub views through the code instead of the story board. No idea why it works, but it did.
