How to show my url json data to collection view - ios

Question

I have get data from one url with authorized header and i convert to json.
In my json i am having only pdf file. But i don't want to show pdf file. I want to show the file name ( eg : document1.pdf, document2.pdf ).and also i am having 3 section - each contain 10 documents. So i need to show name of the document.
I saw some tutorials which using only image not document file. So how to show my document name alone to collection view.
One more question. does i need to decode to show my data or don't want to do that. Help me out.Thanks in advance !

NSMutableArry *arrayPDFName = [[NSMutableArray alloc]init];
NSDictionary *jsonResults = [NSJSONSerialization JSONObjectWithData:returnData options:NSJSONReadingMutableContainers error:nil];
NSDictionary *dictOriginal = [jsonResultsvalueForKey:#"original"];
NSArray *arrayFiles = [[dictOriginal valueForKey:#"files"] copy];
NSLog(#"The arrayFiles are - %#",arrayFiles);
for(int i=0;i<[arrayFiles count];i++)
{
NSString *strCreatedTime = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:i] valueForKey:#"created_time"]];
NSString *strLastModifiedTime = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:i] valueForKey:#"last_modified_time"]];
NSString *strID = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:i] valueForKey:#"id"]];
NSString *strName = [NSString stringWithFormat:#"%#",[[arrayFiles objectAtIndex:i] valueForKey:#"name"]];
NSLog(#"The created_time is - %#",strCreatedTime);
NSLog(#"The last_modified_time is - %#",strLastModifiedTime);
NSLog(#"The is is - %#",strID);
NSLog(#"The name is - %#",strName);
[arrayPDFName addObject:strName];
}
}
in collectionview you need use the above arrayPDFName(in collection view delegates methods)
Showing data in CollectionView
- (void)viewDidLoad
{
[super viewDidLoad];
[self getResponse];
UICollectionViewFlowLayout *flowLayout = [[UICollectionViewFlowLayout alloc] init];
flowLayout.scrollDirection = UICollectionViewScrollDirectionVertical;
//Register the custom cell for collection view
UINib *cellNib = [UINib nibWithNibName:#"CustomCell" bundle:nil];
[collectionViewHorizontalVertical registerNib:cellNib forCellWithReuseIdentifier:#"cvCell"];
}
//Collection View Delegates method
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
return 1;
}
-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
return arrayPDFName.count;
}
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cvCell";
CustomCell *cell = (CustomCell *)[collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
//data for text
cell.textField.text = [arrayPDFName objectAtIndex:indexPath.row];
//OR Image
cell.imgViewCollection.image = [UIImage imageNamed:[arrayPDFName objectAtIndex:indexPath.row]];
return cell;
}
// If you want to set the cell height
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
return CGSizeMake(200, 200); //Please give your required size
}
