Make a map fill the screen and return to the original size

  • 772

Hi, I'm trying to make it so that when you touch a map in one of my views, the map occupies the entire screen and with another touch it shrinks to its original size without it disappearing.

This is the structure of my views: hierarchy

And when executing the following code:

 override func viewDidLoad() {
    super.viewDidLoad()

    let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(VistaDetalleNivelUnoVC.ModifySize))
    mapLocation.addGestureRecognizer(tap)
}

func dismissFullscreenImage(sender: UITapGestureRecognizer) {
    sender.view?.removeFromSuperview()
}

func ModifySize () {
    print("Full")
    let screenSize: CGRect = UIScreen.mainScreen().bounds
    let screenWidth = screenSize.width
    let screenHeight = screenSize.height
    mapLocation.userInteractionEnabled = true
    mapLocation.multipleTouchEnabled = true
    mapLocation.frame = CGRect(x: 0, y: 0, width: screenWidth, height: screenHeight)
    self.view.bringSubviewToFront(mapLocation)
    print(mapLocation.frame)

    let tap = UITapGestureRecognizer(target: self, action: #selector(VistaDetalleNivelUnoVC.dismissFullscreenImage(_:)))
    mapLocation.addGestureRecognizer(tap)
}

When you click on the map it looks like this:

and when I tap on it again it disappears completely:

    If you do this you will always delete the map

    func dismissFullscreenImage(sender: UITapGestureRecognizer) {
    sender.view?.removeFromSuperview()
}

    What you need is to resize the map again not delete it from the superview , so just do the same thing you do to make it bigger which is to change its frame
