I have my firstVC in the main window and when a button is pressed I animate a second window from the bottom right hand corner that stops almost 3/4 way of the entire screen. Everything animates fine. The problem is I have a cancelButton (red X) on the outside of the second window and when I tap it nothing registers. I know it's outside of it's parent's bounds so I tried a hitTest
but still nothing.
func setAnchorsForCancelButton() {
secondWindow?.addSubview(self.cancelButton)
cancelButton.bottomAnchor.constraint(equalTo: secondWindow!.topAnchor, constant: -10).isActive = true
cancelButton.leadingAnchor.constraint(equalTo: secondWindow!.leadingAnchor, constant: 10).isActive = true
// width and height are 35
}
func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
let translatedPoint = cancelButton.convert(point, from: secondWindow!.rootViewController!.view)
if (cancelButton.bounds.contains(translatedPoint)) {
return cancelButton.hitTest(translatedPoint, with: event)
}
return hitTest(point, with: event)
}
The Red X is a cancel button that is on the outside of the second window. It's not receiving the touch events
How can I get it to receive the touch events while still outside of the second window?
code that launches the Second UIWindow:
class SecondWindow: NSObject {
lazy var cancelButton: UIButton = {
// button created
}()
var secondWindow: UIWindow?
let webViewVC = WebViewController() // instagram gets shown in here
let navVC: UINavigationController?
override init() {
super.init()
// some Notifications are in here
}
func animateFromBottom() {
guard let keyWindow = UIApplication.shared.keyWindow else { return }
let startingFrame = CGRect(x: keyWindow.frame.width - 10,
y: keyWindow.frame.height - 10,
width: 10,
height: 10)
let endingRect = CGRect(x: 0,
y: 150,
width: keyWindow.frame.width,
height: keyWindow.frame.height)
let navVC = UINavigationController(rootViewController: webViewVC)
secondWindow = UIWindow(frame: startingFrame)
secondWindow?.windowLevel = UIWindow.Level.normal
secondWindow?.rootViewController = navVC!
secondWindow?.makeKey()
secondWindow?.isHidden = false
// a function with an animation animates the second window to the endingFrame
setAnchorsForCancelButton()
}
func setAnchorsForCancelButton() {
secondWindow?.addSubview(self.cancelButton)
cancelButton.bottomAnchor.constraint(equalTo: secondWindow!.topAnchor, constant: -10).isActive = true
cancelButton.leadingAnchor.constraint(equalTo: secondWindow!.leadingAnchor, constant: 10).isActive = true
// width and height are 35
}
func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
let translatedPoint = cancelButton.convert(point, from: secondWindow!.rootViewController!.view)
if (cancelButton.bounds.contains(translatedPoint)) {
return cancelButton.hitTest(translatedPoint, with: event)
}
return hitTest(point, with: event)
}
}
button from firstVC that launches the second window:
@obj func launchSecondWindow(_ sender: UIButton) {
let secondWindow = SecondWindow()
secondWidow.animateFromBottom()
}
I found the answer here and here
I subclassed UIWindow and did an override to the hitTest inside of there.
class AnotherWindow: UIWindow {
override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
for subview in subviews.reversed() {
let convertedPoint = subview.convert(point, from: self)
if let candidate = subview.hitTest(convertedPoint, with: event) {
return candidate
}
}
return self
}
}
Then inside the SecondWindow class I used my subclass instead:
// this was what I originally used
var secondWindow: UIWindow?
// **This is what I'm using now**
var secondWindow: AnotherWindow?
