Adjusting the height of a wkwebview programmatically - html

Question

This is my first question on Stack Overflow. I just started learning swift programming and got sucked into something.
I followed IAP tutorials on YouTube and successfully implemented AdMob banners and interstitial ads in my app. I was also able to turn off ads using the IAP. My question is:
I have a view in which I have two UI elements (WKWebViewand a GADBannerView). The WKWebView element covers 90% of the screen starting from x:0,y:0, whereas the GADBannerView element covers 10%. I turned off ads and hid the GADBannerView element using IAP.
Now I want to dynamically/programmatically adjust the WKWebView size to fill the entire screen, i.e 100%. In other words, I want the WKWebView element to extend over the hidden GADBannerView element.
This is because hiding the GADBannerView leaves a blank field which is not cool to the view and the WKWebView looks truncated.
Please note that neither of the views are subviews. Both are independent views added separately. I understand that I can initially make the web view fill entire screen, add the GADBannerView on top of it, and when I remove ads and hid the GADBannerView, the web view will fill screen. That is not what I want because some content of the web view can not be seen using this approach. If I have a button at the end of HTML page that loads on the web view, this button can not be clicked because it will always be behind the gad banner view even when scrolling reached the bottom. Yes, you can scroll and hold to see the button, but once you release it, it will go back down.
So as a recap, I have two separate views and want to hid one and extend the length of the other to cover the entire screen.
Please tell me how to achieve that.
thirdBannerView.isHidden = true //Hide the banner view
//then code below to increase the size of the web view to equal device //screen width and height i.e full screen.
func webViewDidFinishLoad(webView: WKWebView) {
//let screenBounds = UIScreen.main.bounds
// let heightq = screenBounds.height
//let widthq = screenBounds.width
//webView.frame.size.height = heightq
//webView.frame.size = webView.sizeThatFits(CGSize.zero)
//webView.frame = CGRectMake(0, 0, widthq, heightq);
webView.frame = CGRect(x: 0, y: 0, width: self.view.frame.width, height: self.view.frame.height)
}
This code is not effective at all as nothing changes. Please let me know how to achieve this.

Answer 1

This particular scenario looks promising for applying UIStackview. Add your two view ( WKWebview and GADBannerView). apply fixed height for the GADBannerview. Whenever necessary just hide the GADBannerview.
Sample code
class StackviewController : UIViewController {
let stackview: UIStackView = {
let view = UIStackView()
view.axis = .vertical
view.distribution = .fill
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
// Your WKWebview here
let sampleWKWebView: UIView = {
let view = UIView()
view.backgroundColor = .red
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
// Your GADBannerView here
let sampleGADBannerView: UIView = {
let view = UIView()
view.backgroundColor = .green
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
override func viewDidLoad() {
super.viewDidLoad()
setupViews()
}
func setupViews() {
view.addSubview(stackview)
stackview.addArrangedSubview(sampleWKWebView)
stackview.addArrangedSubview(sampleGADBannerView)
NSLayoutConstraint.activate([
stackview.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 0.0),
stackview.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 0.0),
stackview.topAnchor.constraint(equalTo: view.topAnchor, constant: 0.0),
stackview.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 0.0),
sampleGADBannerView.heightAnchor.constraint(equalToConstant: 100.0)
])
// Enable this line to hide the GADBannerView
// sampleGADBannerView.isHidden = true
}
}
Here is the output
I use two UIView to represent the WKWebView & GADBannerView. In the sample code uncomment the following to hide the bottom banner like green view.
sampleGADBannerView.isHidden = true
