I have not tested what I am about to write, but you could try this:
-(void)viewDidLoad {
//declare before NSMutableArray *_mutableArray;
_mutableArray = [[NSMutableArray alloc] init];
}
...
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
//dismiss UIImagePickerController
[picker dismissViewControllerAnimated:YES completion:Nil];
//take image from info
UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
//store image into NSMutableArray
[_mutableArray addObject:image];
//reload collectionView
[self.collectionView reloadData];
}
and in collectionView cellForItemAtIndexPath
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
//this is a custom CollectionViewCell
CollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"Cell" forIndexPath:indexPath];
cell.imageA.image = [_mutableArray objectAtIndex:indexPath.row];
return cell;
}
