adding a background image to a ui collection view

Question

I am new to iOS development and I was wondering how do I add a background image that will repeat vertically to my UI Collection View that I have created to display an array of images?

Answer 1

For swift, add to viewDidLoad():

    self.collectionView?.backgroundColor = UIColor(patternImage: UIImage(named: "background")!)

Answer 2

This will work as well and I think is more correct than the work around with the background color. Go for the backgroundView directly.

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.collectionView.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourImage.png"]];

}

Answer 3

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.collectionView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"imageName.pnd"]];
}
