Question

Answer 1

You can give different CellIdentifiers for every TableViewCell and createa different rows in InterfaceBuilder or inside
cellForRowAtIndexPath
Dont forget to provide dataSource and delegate for every collectionView that you will create for TableViewCell
Pseudocode:
YN Means YourNamespace
YNDataSourceDelegate1* data1;
YNDataSourceDelegate2* data2;
YNDataSourceDelegate3* data3;
YNDataSourceDelegate4* data4;
const NSInteger COLLECTION_VIEW_TAG = 1001;
NSArray* providers=#[data1,data2,data3,data4];
NSArray* rowIds=#[#"row1",#"row2",#"row3",#"row4"];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:rowIds[indexPath.row]];
UICollectionView * collectionView = (UICollectionView*)[cell viewWithTag:COLLECTION_VIEW_TAG];
collectionView.dataSource = providers[indexPath.row];
return cell;
}

This code will help you
yourViewController.h
#interface testingvc : UIViewController
<
UITableViewDelegate,
UITableViewDataSource,
UICollectionViewDelegate,
UICollectionViewDataSource
>
{
IBOutlet UITableView *tbleeView;
}
yourViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
tbleeView.delegate=self;
tbleeView.dataSource=self;
tbleeView.pagingEnabled=YES;
}
yourTableViewCell.h(UITableViewCell)
#property(strong,nonatomic)IBOutlet UICollectionView *clview;
yourViewController.m
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
//#warning Incomplete implementation, return the number of sections
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
//#warning Incomplete implementation, return the number of rows
return 10;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
static NSString *identifierDriver = #"abcdefgh";
yourTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifierDriver forIndexPath:indexPath];
//testing table cell is a UITableViewCell
if (cell == nil)
{
cell = [[testingTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifierDriver];
}
cell.backgroundColor=[UIColor yellowColor];
//#property(strong,nonatomic)IBOutlet UICollectionView *clview;-this method is implement in UITableViewCell
// call collection view delegate method in table view cell.
cell.clview.delegate=self;
cell.clview.dataSource=self;
cell.clview.parentIndexpath = indexPath;
cell.clview.backgroundColor=[UIColor magentaColor];
cell.clview.pagingEnabled=YES;//optional
return cell;
}
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
NSArray *collectionViewArray = [_arrayProducts [[(IndexedCollectionView *)collectionView parentIndexpath].row]objectForKey:#"inventory"];//arrProducts is an array where i get all the data from webservice
return [collectionViewArray count];
}
- (NSIndexPath *)indexPathForRowAtPoint:(CGPoint)point
{
return 0;
}
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
yourColloectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"abcdef" forIndexPath:indexPath];
NSArray *Products = [_arrayProducts[[(yourCollectionView *)collectionView parentIndexpath].row]objectForKey:#"inventory"];//arrProducts is an array where i get all the data from webservice
NSLog(#"object ibde xis ----%ld",[Products count]);
if (indexPath.row>[Products count]-1 )
{
NSLog(#"index not found");
}
else
{
NSDictionary *dictdata = [Products objectAtIndex:indexPath.row];
NSLog(#"dictdata is =====%#",dictdata);
//do your code here
}
if (indexPath.row % 2)
{
cell.backgroundColor=[UIColor brownColor];;
}
else
cell.backgroundColor=[UIColor redColor];;
return cell;
}
- (CGFloat)collectionView:(UICollectionView *)collectionView
layout:(UICollectionViewLayout *)collectionViewLayout
minimumLineSpacingForSectionAtIndex:(NSInteger)section
{
return 0;
}
- (void)collectionView:(IndexedCollectionView *)collectionView
didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
NSInteger tableindex = collectionView.parentIndexpath.row;
NSLog(#"collection path row is ----%ld",tableindex);
NSLog(#"collection path row is ----%ld",indexPath.row);
//you can get all that index path number . Enjoy :)
