UICollectionView cell is not getting added as a subview of UICollectionView - ios

Question

I am new to UICollectionView.
I have followed this tutorial to learn how to use a UICollectionView, but the problem is that in the .xib (not using storyboard) I am not able to add UICollectionViewCell as a subview of UICollectionView.
In the tutorial the cell is automatically created under UICollectionView in the .xib.
Any help would be appreciated.

Answer 1

That tutorial is for working in stroy board in xib you ve to create custom cell first create view controller add UicollectionView to view Controller
then create custom class for collection cell
then craete empty xib resource and add collection view cell
and set class name and identifier for that control
then create delegates method to add custom cell to ur collectionViewController
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"customCell";
customCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
return cell;
}

Answer 2

You can start your controller and create a custom collection view cell for setting your view element and then you can use it into your collection view controller into xib, here is a good tutorials to do this http://adoptioncurve.net/archives/2012/09/a-simple-uicollectionview-tutorial/

Answer 3

Use this code for creation of collectionview and adding the subview.
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView {
return [imageArray count];
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
NSMutableArray *sectionArray = [imageArray objectAtIndex:section];
return [sectionArray count];
}
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
// Setup cell identifier
static NSString *cellIdentifier = #"cvCell";
/* Uncomment this block to use nib-based cells */
// UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
// UILabel *titleLabel = (UILabel *)[cell viewWithTag:100];
// [titleLabel setText:cellData];
/* end of nib-based cell block */
/* Uncomment this block to use subclass-based cells */
CVCell *cell = (CVCell *)[collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
NSMutableArray *data = [imageArray objectAtIndex:indexPath.section];
NSString *cellData = [data objectAtIndex:indexPath.row];
[cell.titleLabel setText:cellData];
cell.imageView.image = [UIImage imageNamed:[imageArray[indexPath.section] objectAtIndex:indexPath.row]];
return cell;
}
- (UICollectionReusableView *)collectionView:(UICollectionView *)collectionView viewForSupplementaryElementOfKind:(NSString *)kind atIndexPath:(NSIndexPath *)indexPath
{
header *sectionHeader;
if (kind == UICollectionElementKindSectionHeader)
{
sectionHeader = [collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:#"Hello" forIndexPath:indexPath];
}
UICollectionReusableView *test=[collectionView dequeueReusableSupplementaryViewOfKind:UICollectionElementKindSectionHeader withReuseIdentifier:#"Hello" forIndexPath:indexPath];
return test;
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout referenceSizeForHeaderInSection:(NSInteger)section
{
if (section == 3) {
return CGSizeMake(0, 100);
}
return CGSizeZero;
}
- (NSString *)applicationDocumentsDirectory {
return [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
}
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
return CGSizeMake(80, 80);
}
