I trying to display toast on bottom of screen but, when keypad appears toast is hiding behind keypad. Please any one suggest me the solution. Below is my code which i tried.
func displayToast(_ message : String) {
guard let delegate = UIApplication.shared.delegate as? AppDelegate, let window = delegate.window else {
return
}
if let toast = window.subviews.first(where: { $0 is UILabel && $0.tag == -1001 }) {
toast.removeFromSuperview()
}
let toastView = UILabel()
toastView.backgroundColor = UIColor.black.withAlphaComponent(0.7)
toastView.textColor = UIColor.white
toastView.textAlignment = .center
toastView.font = UIFont(name: "Font-name", size: 17)
toastView.layer.cornerRadius = 15
toastView.clipsToBounds = true
toastView.text = message
toastView.numberOfLines = 0
toastView.alpha = 0
toastView.translatesAutoresizingMaskIntoConstraints = false
toastView.tag = -1001
let windowww = UIApplication.shared.windows[UIApplication.shared.windows.count - 1]
windowww.addSubview(toastView)
let horizontalCenterContraint: NSLayoutConstraint = NSLayoutConstraint(item: toastView, attribute: .centerX, relatedBy: .equal, toItem: windowww, attribute: .centerX, multiplier: 1, constant: 0)
let widthContraint: NSLayoutConstraint = NSLayoutConstraint(item: toastView, attribute: .width, relatedBy: .equal, toItem: nil, attribute: .width, multiplier: 1, constant: (self.frame.size.width-25) )
let verticalContraint: [NSLayoutConstraint] = NSLayoutConstraint.constraints(withVisualFormat: "V:|-(>=200)-[toastView(==50)]-68-|", options: [.alignAllCenterX, .alignAllCenterY], metrics: nil, views: ["toastView": toastView])
NSLayoutConstraint.activate([horizontalCenterContraint, widthContraint])
NSLayoutConstraint.activate(verticalContraint)
UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {
toastView.alpha = 1
}, completion: nil)
DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(3), execute: {
UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {
toastView.alpha = 0
}, completion: { finished in
toastView.removeFromSuperview()
})
})
}
