Ios 以编程方式在UICollectionView单元格的每个uiimage上添加UIButtons

我有一个UIViewController，其中包含一个通过编程方式创建的UICollectionView图像库。我想在UICollectionView单元格的每个uiimage上添加一个按钮： .h文件中的代码是：

#import <UIKit/UIKit.h>

@interface CMFViewController : UIViewController <UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout>

@end

#import "CMFViewController.h"
#import "CMFGalleryCell.h"

@interface CMFViewController ()
@property (nonatomic, weak) IBOutlet UICollectionView *collectionView;
@property (nonatomic, strong) NSArray *dataArray;
@property (nonatomic) int currentIndex;

@end

@implementation CMFViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self loadImages];
    [self setupCollectionView];

}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
