如何在Swift中将背景图像添加到UICollectionViewCell？

Question

I had assumed that it would be easy to add a background image to a UICollectionViewCell , but I am having trouble figuring it out. I have a border image like this that I want to add to every cell in my UICollectionView .

border.png

I couldn't see an option to add it in the Interface Builder and I'm not sure which method to use on UICollectionViewCell programmatically.

I have seen these similar questions:

• UICollectionView Cell with Image, change Background with click (image is already added)
• How to add a background image to UICollectionView that will scroll and zoom will cells ( UICollectionView , not UICollectionViewCell )

Answer 1

I know this is a old question, with an accepted answer. But why not just set the border of the cell like so:

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell
{
    let cell  = collectionView.dequeueReusableCellWithReuseIdentifier("Cell", forIndexPath: indexPath) 

        cell.layer.borderWidth = 1.5
        cell.layer.borderColor = UIColor.blueColor().CGColor
        cell.layer.cornerRadius = 4

  return cell
}

That way you don't need to use a image. Just adjust the borderWidth and cornerRadius until you get the desired effect.

Answer 2

let View=UIView()
View.backgroundColor=UIColor(patternImage:UIImage(named:"border.png")!)
cell.backgroundView=View

in uicollectionview cellForItemAtIndexPath method

Answer 3

将UIImageView添加到CollectionViewCell并将此图像设置为图像。
