I'm using UICollectionView to generate a image gallery.I used UIImage inside the UICollectionView Cell to load the images. I need to select UICollectionView Cell by Long Press (not by single tap).

Answer 1

Just pick up the didSelectItemAtIndexPath delegate callback, grab the cell, and add an image as a subview.
-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
YourCollectionViewCell *cell = (YourCollectionViewCell*)[collectionView cellForItemAtIndexPath:indexPath];
UIImageView *yourImageView = [[UIImageView alloc]initWithFrame:CGRectMake(x, y, width, height)];//whichever frame you want it to appear at
yourImageView.image = [UIImage imageNamed:#"yourImageName"];//set the image
[cell.yourBaseImage addSubview:yourImageView];//or add it to whatever part of the cell you want
}
Or alternatively, just have a hidden imageView already setup inside of Storyboard. And then unhide it and set the image inside didSelectItemAtIndexPath.
