Answer 1

Mr. Beans answer works well. However, his answer uses a small width & isn't multi-line friendly. Use this instead.

func showToastFaded(message : String) {


    let toastLabel = UILabel(frame: CGRect(x: self.view.frame.size.width/2 - 125, y: self.view.frame.size.height-100, width: 250, height: 35))
    toastLabel.numberOfLines = 0
    toastLabel.backgroundColor = UIColor.black.withAlphaComponent(0.6)
    toastLabel.textColor = UIColor.white
    toastLabel.textAlignment = .center;
    toastLabel.text = message
    toastLabel.alpha = 1.0
    toastLabel.layer.cornerRadius = 10;
    toastLabel.clipsToBounds  =  true
    toastLabel.sizeToFit()
    toastLabel.frame = CGRect( x: toastLabel.frame.minX, y: toastLabel.frame.minY,width:   toastLabel.frame.width + 20, height: toastLabel.frame.height + 8)

    self.view.addSubview(toastLabel)
    UIView.animate(withDuration: 4.0, delay: 0.1, options: .curveEaseOut, animations: {
        toastLabel.alpha = 0.0
    }, completion: {(isCompleted) in
        toastLabel.removeFromSuperview()
    })
}

What exactly you need is https://github.com/Rannie/Toast-Swift/blob/master/SwiftToastDemo/Toast/HRToast%2BUIView.swift .

Download the HRToast + UIView.swift class and drag and drop to project. Make sure you check 'copy items if needed' on dialogue box.

  //Usage:
  self.view.makeToast(message: "Simple Toast")
  self.view.makeToast(message: "Simple Toast", duration: 2.0, position:HRToastPositionTop)

  self.view.makeToast(message: "Simple Toast", duration: 2.0, position: HRToastPositionCenter, image: UIImage(named: "ic_120x120")!)

  self.view.makeToast(message: "It is just awesome", duration: 2.0, position: HRToastPositionDefault, title: "Simple Toast")

  self.view.makeToast(message: "It is just awesome", duration: 2.0, position: HRToastPositionCenter, title: "Simple Toast", image: UIImage(named: "ic_120x120")!)

  self.view.makeToastActivity()
  self.view.makeToastActivity(position: HRToastPositionCenter)
  self.view.makeToastActivity(position: HRToastPositionDefault, message: "Loading")
  self.view.makeToastActivityWithMessage(message: "Loading")

I have been using this extension when ever i need toast-message like android.. Just copy the extension to you project and then in your UIViewController class, call the function like

self.toastMessage("Downloading...") 
// Extention is below

extension UIViewController {
  func toastMessage(_ message: String){
    guard let window = UIApplication.shared.keyWindow else {return}
    let messageLbl = UILabel()
    messageLbl.text = message
    messageLbl.textAlignment = .center
    messageLbl.font = UIFont.systemFont(ofSize: 12)
    messageLbl.textColor = .white
    messageLbl.backgroundColor = UIColor(white: 0, alpha: 0.5)

    let textSize:CGSize = messageLbl.intrinsicContentSize
    let labelWidth = min(textSize.width, window.frame.width - 40)

    messageLbl.frame = CGRect(x: 20, y: window.frame.height - 90, width: labelWidth + 30, height: textSize.height + 20)
    messageLbl.center.x = window.center.x
    messageLbl.layer.cornerRadius = messageLbl.frame.height/2
    messageLbl.layer.masksToBounds = true
    window.addSubview(messageLbl)

    DispatchQueue.main.asyncAfter(deadline: .now() + 1) {

    UIView.animate(withDuration: 1, animations: {
        messageLbl.alpha = 0
    }) { (_) in
        messageLbl.removeFromSuperview()
    }
    }
}}

I know there are accepted answers but they all seem to have a big flaw - if you show several toasts in a short period of time they will show on top of each other. Here is my implementation which takes this problem into consideration:

class Toast: UILabel {

private let BOTTOM_MARGIN: CGFloat = 16
private let SIDE_MARGIN: CGFloat = 16
private let HEIGHT: CGFloat = 35
private let SHOW_TIME_SECONDS = TimeInterval(3)
private let BACKGROUND_COLOR = UIColor.darkGray.withAlphaComponent(0.7).cgColor
private let TEXT_COLOR = UIColor.white
private let ANIMATION_DURATION_SEC = 0.33

private static var queue: [ToastHolder] = []
private static var showing: Toast?

init(_ text: String) {
    super.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0))

    self.text = text
    self.textColor = TEXT_COLOR
    textAlignment = .center
    self.layer.backgroundColor = BACKGROUND_COLOR
    self.layer.cornerRadius = 5
}

public func show(_ parent: UIViewController) {
    frame = CGRect(x: SIDE_MARGIN, y: UIScreen.main.bounds.height - BOTTOM_MARGIN - HEIGHT, width: UIScreen.main.bounds.width - 2 * SIDE_MARGIN, height: HEIGHT)

    if Toast.showing == nil {
        Log.d("showing \(String(describing: text))")
        Toast.showing = self
        alpha = 0
        parent.view.addSubview(self)
        UIView.animate(withDuration: ANIMATION_DURATION_SEC, animations: {
            self.alpha = 1
        }, completion: { (completed) in
            Timer.scheduledTimer(timeInterval: self.SHOW_TIME_SECONDS, target: self, selector: #selector(self.onTimeout), userInfo: nil, repeats: false)
        })
    } else {
        Toast.queue.append(ToastHolder(self, parent))
    }
}

@objc func onTimeout() {        
    UIView.animate(withDuration: ANIMATION_DURATION_SEC, animations: {
        self.alpha = 0
    }, completion: { (completed) in
        Toast.showing = nil
        self.removeFromSuperview()

        if !Toast.queue.isEmpty {
            let holder = Toast.queue.removeFirst()
            holder.toast.show(holder.parent)
        }
    })
}

required init?(coder aDecoder: NSCoder) {
    fatalError("this initializer is not supported")
}

private class ToastHolder {
    let toast: Toast
    let parent: UIViewController

    init(_ t: Toast, _ p: UIViewController) {
        toast = t
        parent = p
    }
}
}

Usage:

Toast("my message").show(self)

Hope it helps someone.

I have modified the @samo's answer with:

• Proper variables name's

• Leading and Trailing constraints changed to center constraint.

Now message will adjust its width according to message and it will be centred.

extension UIViewController {
        func showToast(message: String) {
            let toastContainer = UIView(frame: CGRect())
            toastContainer.backgroundColor = UIColor.black.withAlphaComponent(0.6)
            toastContainer.alpha = 0.0
            toastContainer.layer.cornerRadius = 20;
            toastContainer.clipsToBounds  =  true

            let toastLabel = UILabel(frame: CGRect())
            toastLabel.textColor = UIColor.white
            toastLabel.textAlignment = .center;
            toastLabel.font.withSize(12.0)
            toastLabel.text = message
            toastLabel.clipsToBounds  =  true
            toastLabel.numberOfLines = 0

            toastContainer.addSubview(toastLabel)
            self.view.addSubview(toastContainer)

            toastLabel.translatesAutoresizingMaskIntoConstraints = false
            toastContainer.translatesAutoresizingMaskIntoConstraints = false

            let centerX = NSLayoutConstraint(item: toastLabel, attribute: .centerX, relatedBy: .equal, toItem: toastContainer, attribute: .centerXWithinMargins, multiplier: 1, constant: 0)
            let lableBottom = NSLayoutConstraint(item: toastLabel, attribute: .bottom, relatedBy: .equal, toItem: toastContainer, attribute: .bottom, multiplier: 1, constant: -15)
            let lableTop = NSLayoutConstraint(item: toastLabel, attribute: .top, relatedBy: .equal, toItem: toastContainer, attribute: .top, multiplier: 1, constant: 15)
            toastContainer.addConstraints([centerX, lableBottom, lableTop])

            let containerCenterX = NSLayoutConstraint(item: toastContainer, attribute: .centerX, relatedBy: .equal, toItem: self.view, attribute: .centerX, multiplier: 1, constant: 0)
            let containerTrailing = NSLayoutConstraint(item: toastContainer, attribute: .width, relatedBy: .equal, toItem: toastLabel, attribute: .width, multiplier: 1.1, constant: 0)
            let containerBottom = NSLayoutConstraint(item: toastContainer, attribute: .bottom, relatedBy: .equal, toItem: self.view, attribute: .bottom, multiplier: 1, constant: -75)
            self.view.addConstraints([containerCenterX,containerTrailing, containerBottom])

            UIView.animate(withDuration: 0.5, delay: 0.0, options: .curveEaseIn, animations: {
                toastContainer.alpha = 1.0
            }, completion: { _ in
                UIView.animate(withDuration: 0.5, delay: 1.5, options: .curveEaseOut, animations: {
                    toastContainer.alpha = 0.0
                }, completion: {_ in
                    toastContainer.removeFromSuperview()
                })
            })
        }
    }

Answer 6

extension UIViewController {

func showToast(message : String, font: UIFont) {

    let toastLabel = UILabel(frame: CGRect(x: self.view.frame.size.width/2 - 75, y: self.view.frame.size.height-100, width: 150, height: 35))
    toastLabel.backgroundColor = UIColor.black.withAlphaComponent(0.6)
    toastLabel.textColor = UIColor.white
    toastLabel.font = font
    toastLabel.textAlignment = .center;
    toastLabel.text = message
    toastLabel.alpha = 1.0
    toastLabel.layer.cornerRadius = 10;
    toastLabel.clipsToBounds  =  true
    self.view.addSubview(toastLabel)
    UIView.animate(withDuration: 4.0, delay: 0.1, options: .curveEaseOut, animations: {
         toastLabel.alpha = 0.0
    }, completion: {(isCompleted) in
        toastLabel.removeFromSuperview()
    })
} }

Use like this:

self.showToast(message: "Your Toast Message", font: .systemFont(ofSize: 12.0))
