How to know which UIView is clicked In Swift

Question

There are 8 UIViews which I want to navigate to the other View Controller when clicked but currently when I clicked on any of the 8 UIView It points to only one view controller that is DetailedViewController. I had put the hard coded navigation on click but I want that every UIView should lead to a different ViewController And I am Unable to do that. Here is my code:-

class HomeViewController: UIViewController {
var view1:UIView!
var view2:UIView!
var view3:UIView!
var view4:UIView!
var view5:UIView!
var view6:UIView!
var view7:UIView!
var view8:UIView!



override func viewDidLoad() {

    super.viewDidLoad();

    view1 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xf6b37f, alpha: 1.0), title:"Kerala", logoImage:UIImage(named: "CD_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "kerala")!), backViewTitle:"Area:38,863 Km \n Capital: Thiruvananthapuram")
    view2 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xf9a451, alpha: 1.0), title:"Goa", logoImage:UIImage(named: "coffee_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "goa")!), backViewTitle:"Area:38,863 Km \n Capital: Panaji")
    view3 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xf78d60, alpha: 1.0), title:"Delhi", logoImage:UIImage(named: "message_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "delhi")!), backViewTitle:"Area:38,863 Km \n Capital: Delhi")
    view4 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xfc7d38, alpha: 1.0), title:"Gujarat", logoImage:UIImage(named: "things_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "gujarat")!), backViewTitle:"Area:38,863 Km \n Capital: Gandhinagar")
    view5 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xeb6100, alpha: 1.0), title:"Maharashtra", logoImage:UIImage(named: "clock_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "maharasathra")!), backViewTitle:"Area:38,863 Km \n Capital: Mumbai")
    view6 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xff5e33, alpha: 1.0), title:"Madhya Pradesh", logoImage:UIImage(named: "settings_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "bestplace")!), backViewTitle:"Area:38,863 Km \n Capital: Bhopal")
    view7 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xeb6100, alpha: 1.0), title:"Maharashtra", logoImage:UIImage(named: "clock_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "maharasathra")!), backViewTitle:"Area:38,863 Km \n Capital: Mumbai")
    view8 = self.autoLayoutPanelViewWithColor(UIColor(hex: 0xff5e33, alpha: 1.0), title:"Madhya Pradesh", logoImage:UIImage(named: "settings_grid@156px")!, backViewBackgroundColor:UIColor(patternImage: UIImage(named: "bestplace")!), backViewTitle:"Area:38,863 Km \n Capital: Bhopal")

    self.makeGlobalConstraintsToView(self.view, subviewArray: [view1,view2,view3,view4,view5,view6,view7,view8])

    panelLogo.setTranslatesAutoresizingMaskIntoConstraints(false)
    panelLogo.addSubview(label)
    inPanelView.addSubview(panelLogo)
    inPanelView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|-20-[panelLogo]-20-|",

    inPanelView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-25-[panelLogo]-25-|",
        options: NSLayoutFormatOptions.AlignAllBaseline,
        metrics: nil,
        views: ["panelLogo":panelLogo]))

}

}

This is the output. Need help!

UIGestureRecognizer has a property called view which, from the docs, says "The view the gesture recognizer is attached to. (read-only)". So in your action method (looks like flipView ) you can call sender.view and then act on it.
