How do you add Facebook shimmering to images and UIViews?

Question

I'm trying out Facebook shimmering library and I was able to add shimmering to text label using this code.

    self.shimmeringView = FBShimmeringView(frame: CGRectMake(0, 0, 200, (self.navigationController?.navigationBar.bounds.height)!))
    self.shimmeringView.contentView = navLabel
    self.navigationItem.titleView = self.shimmeringView
    self.shimmeringView.shimmering = true

However, I am unable to make an image or an UIImage shimmer. Is this even possible? Thanks!

Answer 1

What you are doing for shimmering the UIImageView is wrong.

1. You did not add shimmer to the view as a subview.
2. You did not set the UIImageView as the contentView for the shimmer.

Update your code with something like that:

@IBOutlet var imageView: UIImageView!

var shimmer: FBShimmeringView!

override func viewDidLoad() {
    shimmer = FBShimmeringView(frame: self.imageView.frame)
    shimmer.contentView = imageView
    self.view.addSubview(shimmer)
    shimmer.isShimmering = true
}
