Button click method not working

[Gantaios]

Hi thanks for your great control just want to add gestures to the headerviw how can we achieve that please tell me

[hongzhou85]

Same i cannot detect any gestures or IBAction in the parallax header. How do intercept the touch?

Same here. This would be an awesome thing to know. Thanks!

I have achieved it by storing a reference of the tableViewController or scrollViewController or collectionViewController in the headerView. Then set the buttons' touchGestureRecognizer target to your reference and have the function in there to handle the action. It should works that way.

For the header:

class HeaderView : UIVIewController {
  @IBOutlet weak var button : UIButton!
  var parent: UIViewController?  // Usually your tableview/scrollview/collectionview

  override viewDidLoad() {
    let tapGestureRecognizer = UITapGestureRecognizer(target:self.parent!, action:#selector(ParentViewCollection.actionGesture(_:)))
        button.userInteractionEnabled = true
        button.addGestureRecognizer(tapGestureRecognizer)
  }
}

For the "parent":

class ParentViewController : UIViewController {
   let header : HeaderView = HeaderView()

   override viewDidLoad() {
        header.parent = self
        self.collectionView!.parallaxHeader.view = header.view
        self.collectionView!.parallaxHeader.height = headerHeight
        self.collectionView!.parallaxHeader.mode = MXParallaxHeaderMode.Fill
        self.collectionView!.parallaxHeader.minimumHeight = 0
   }

   func actionGesture(sender : UIGestureRecognizer) {
        // here you can do what you want with the button
    }
}

This is a good approach @hongzhou85. Instead of setting a parentproperty, you can create a delegate and call that delegate on gesture. Another approach would be to create a floating view in your view controller from storyboard, then to attach this floating view to your parallax header. This would allow you to trigger segues directly from your header view.

Great, the floating view seems to work pretty well. Thanks guys!

Any code snippet how you added a floating view. My requirement is that I need to add back button on Top of Parallex header view.
