Vous pouvez essayer avec utableview. Supposons que vous ayez N nombre d'images alors -

 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
        return 1;
    }
        - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
        {
            // 3 is numbers of images per row
            if (n/3 *3 == n)
                return  n/3;

            return n/3 +1;
        }

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;

    }


    int x=5,y=15;

   UIImageView* imgView1=[[UIImageView alloc]initWithFrame:CGRectMake(x, y, 93, 110)];
   imgView1.image=[UIImage imageNamed:[imgarr objectAtIndex:indexPath.row + 0]];
    x+=103;

   UIImageView* imgView2=[[UIImageView alloc]initWithFrame:CGRectMake(x, y, 93, 110)];
    imgView2.image=[UIImage imageNamed:[imgarr objectAtIndex:indexPath.row + 1]];

    x+=103;

    UIImageView* imgView2=[[UIImageView alloc]initWithFrame:CGRectMake(x, y, 93, 110)];
    imgView2.image=[UIImage imageNamed:[imgarr objectAtIndex:indexPath.row + 2]];


    [cell.contentView addSubview:imgView1];
     [cell.contentView addSubview:imgView2];
     [cell.contentView addSubview:imgView3];
    return cell;

}

Create custom class of collection view cell 
and You can pass image name in array. 

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController<UICollectionViewDataSource,UICollectionViewDelegate>

@property (weak, nonatomic) IBOutlet UICollectionView *Collection;

@end

#import "ViewController.h"
#import "CustomCell.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
    [super viewDidLoad];
    [self.Collection registerClass:[CustomCell class] forCellWithReuseIdentifier:@"cell"];
    [self.Collection registerNib:[UINib nibWithNibName:@"CustomCell" bundle:nil] forCellWithReuseIdentifier:@"cell"];
}

-(NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section
{
    return 5;
}
-(NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView
{
    return 4;
}

-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    CustomCell * cell=[collectionView dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];
    cell.imgview.image=[UIImage imageNamed:@"XYZ.png"];
    return cell;
}
