Only my second time using UICollectionView's and perhaps I have bitten off more than I can chew but nevertheless:
I am implementing a UICollectionView (myCollectionView) that uses custom UICollectionViewCell's that I have subclassed. The subclassed cells (FullReceiptCell) contain UITableView's and are the size of the viewcontroller. I am trying to allow for horizontal scrolling between the FullReceiptCells.
The subclassed UICollectionViewController that contains myCollectionView is being pushed on to a nav controller stack. Currently, myCollectionView loas and horizontal scrolling is enabled. However, no cells are visible. I have confirmed that
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
has run and is returning an integer greater than 0. I have also confirmed that myCollectionView's delegate and datasource are properly set in IB to the subclassed UICollectionViewController.
The method where the cells are to be loaded:
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
is not being called.
Here is where I push the UICollectionViewController and my viewDidLoad method within that controller (NOTE: initWithBill is an override of the normal initializer):
In the prior ViewControllers .m file:
FullReceiptViewController *test = [[FullReceiptViewController alloc] initWithBill:currentBill];
test.title = @"Review";
[self.navigationController pushViewController:test animated:YES];
In FullReceiptViewController.m:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
[self.myCollectionView registerClass:[FullReceiptCell class] forCellWithReuseIdentifier:@"FullReceiptCellIdentifier"];
self.myCollectionView.pagingEnabled = YES;
// Setup flowlayout
self.myCollectionViewFlowLayout = [[UICollectionViewFlowLayout alloc] init];
[self.myCollectionViewFlowLayout setItemSize:CGSizeMake(320, 548)];
[self.myCollectionViewFlowLayout setSectionInset:UIEdgeInsetsMake(0, 0, 0, 0)];
[self.myCollectionViewFlowLayout setScrollDirection:UICollectionViewScrollDirectionHorizontal];
self.myCollectionViewFlowLayout.minimumLineSpacing = 0;
self.myCollectionViewFlowLayout.minimumInteritemSpacing = 0;
[self.myCollectionView setCollectionViewLayout:myCollectionViewFlowLayout];
//testing to see if the collection view is loading
self.myCollectionView.backgroundColor = [UIColor colorWithWhite:0.25f alpha:1.0f];
Any clue as to why it is not being called?
