Swift progress view completion actions - swift

Question

Helllo , I am using swift. I have this code that control a progressview on my main view controller. I feed the progress view with a double var containing seconds. Once the progressview has completed i d like to perfom some actions on the main viewcontroller. but i have no idea on where and how to implement actions. here is my code :
class CounterProgressView: UIView {
let sharedDefaults = NSUserDefaults(suiteName: "group.birkyboy.TodayExtensionSharingDefaults")
private let progressLayer: CAShapeLayer = CAShapeLayer()
private var progressLabel: UILabel
required init(coder aDecoder: NSCoder) {
progressLabel = UILabel()
super.init(coder: aDecoder)
createProgressLayer()
}
override init(frame: CGRect) {
progressLabel = UILabel()
super.init(frame: frame)
createProgressLayer()
}
private func createProgressLayer() {
let startAngle = CGFloat(M_PI_2)
let endAngle = CGFloat(M_PI * 2 + M_PI_2)
let centerPoint = CGPointMake(CGRectGetWidth(frame)/2 , CGRectGetHeight(frame)/2)
var gradientMaskLayer = gradientMask()
progressLayer.path = UIBezierPath(arcCenter:centerPoint, radius: CGRectGetWidth(frame)/2 - 30.0, startAngle:startAngle, endAngle:endAngle, clockwise: true).CGPath
progressLayer.backgroundColor = UIColor.clearColor().CGColor
progressLayer.fillColor = UIColor.clearColor().CGColor
progressLayer.strokeColor = UIColor.blackColor().CGColor
progressLayer.lineWidth = 25.0
progressLayer.strokeStart = 0.0
progressLayer.strokeEnd = 0.0
gradientMaskLayer.mask = progressLayer
layer.addSublayer(gradientMaskLayer)
}
private func gradientMask() -> CAGradientLayer {
let gradientLayer = CAGradientLayer()
gradientLayer.frame = bounds
gradientLayer.locations = [1.0, 1.0]
let colorTop: AnyObject = UIColor(red: 255.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 1).CGColor
let colorBottom: AnyObject = UIColor(red: 255.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 0).CGColor
let arrayOfColors: [AnyObject] = [colorTop, colorBottom]
gradientLayer.colors = arrayOfColors
return gradientLayer
}
func hideProgressView() {
progressLayer.strokeEnd = 0.0
progressLayer.removeAllAnimations()
}
func secondsToHoursMinutesSeconds (seconds : Double) -> (Double, Double, Double) {
let (hr, minf) = modf (seconds / 3600)
let (min, secf) = modf (60 * minf)
return (hr, min, 60 * secf)
}
func animateProgressView() {
progressLayer.strokeEnd = 0.0
var temps = sharedDefaults!.objectForKey("roueCounter") as? Double
println(temps)
let animation = CABasicAnimation(keyPath: "strokeEnd")
animation.fromValue = CGFloat(0.0)
animation.toValue = CGFloat(1)
animation.duration = temps!
animation.delegate = self
animation.removedOnCompletion = false
animation.additive = true
animation.fillMode = kCAFillModeForwards
progressLayer.addAnimation(animation, forKey: "strokeEnd")
}
override func animationDidStop(anim: CAAnimation!, finished flag: Bool) {
}
}
And this the functions on the main viewController that call the progressview :
func secondsToHoursMinutesSeconds (seconds : Int) {
sharedDefaults!.setObject(seconds, forKey: "roueCounter")
sharedDefaults!.synchronize()
let (h, m, s) = (seconds / 3600, (seconds % 3600) / 60, (seconds % 3600) % 60)
if m < 10 {
counterInfosLabel.text = "FROM CURRENT TIME IN"
counter.text = "\(h)H0\(m)"
println ("\(h) Hours, 0\(m) Minutes")
counterProgressView.animateProgressView()
} else {
counterInfosLabel.text = "FROM CURRENT TIME IN"
counter.text = "\(h)H\(m)"
println ("\(h) Hours, \(m) Minutes")
counterProgressView.animateProgressView()
}
if h == 0 && (m <= 5 && m > 0){
counter.textColor = UIColor.redColor()
counterInfosLabel.text = "FROM CURRENT TIME IN"
PKNotification.toastBackgroundColor = UIColor.redColor()
PKNotification.toast("You are Illegal in 5 minutes")
counterProgressView.animateProgressView()
var localNotification = UILocalNotification()
localNotification.fireDate = NSDate(timeIntervalSinceNow: 1)
localNotification.alertBody = "You Are Illegal In 5 Minutes."
localNotification.timeZone = NSTimeZone.defaultTimeZone()
localNotification.soundName = "chime.mp3"
localNotification.category = "CATAGORY_1"
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}
if h <= 0 && m <= 0 {
counterInfosLabel.text = "ILLEGAL SINCE"
counter.text = "\(-h)H\(-m)MN"
PKNotification.toastBackgroundColor = UIColor.redColor()
PKNotification.toast("You are Illegal")
var localNotification = UILocalNotification()
localNotification.fireDate = NSDate(timeIntervalSinceNow: 1)
localNotification.alertBody = "You Are Illegal !"
localNotification.timeZone = NSTimeZone.defaultTimeZone()
localNotification.soundName = "chime.mp3"
localNotification.category = "CATAGORY_1"
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
}
}
Thank you for any help you can provide me.

Answer 1

So the progress view knows what to do when the animation is complete, you could give your CounterProgressView a completion handler property:
var completionHandler: (() -> ())?
Then modify the animateProgressView accept and save the completion handler provided by the caller:
func animateProgressView(completionHandler: (() -> ())?) {
self.completionHandler = completionHandler
// set up and start animation
}
You could then have the animation completion delegate method call this closure:
override func animationDidStop(anim: CAAnimation!, finished flag: Bool) {
completionHandler?()
completionHandler = nil
}
Obviously, now when you start the animation, you can specify what you want to happen when the animation is complete:
counterProgressView.animateProgressView() {
// what to do when animation is done
}

Yes i think i did follow exactly :
import UIKit
class CounterProgressView: UIView {
let sharedDefaults = NSUserDefaults(suiteName: "group.birkyboy.TodayExtensionSharingDefaults")
var completionHandler: (() -> ())?
private let progressLayer: CAShapeLayer = CAShapeLayer()
private var progressLabel: UILabel
required init(coder aDecoder: NSCoder) {
progressLabel = UILabel()
super.init(coder: aDecoder)
createProgressLayer()
}
override init(frame: CGRect) {
progressLabel = UILabel()
super.init(frame: frame)
createProgressLayer()
}
private func createProgressLayer() {
let startAngle = CGFloat(M_PI_2)
let endAngle = CGFloat(M_PI * 2 + M_PI_2)
let centerPoint = CGPointMake(CGRectGetWidth(frame)/2 , CGRectGetHeight(frame)/2)
var gradientMaskLayer = gradientMask()
progressLayer.path = UIBezierPath(arcCenter:centerPoint, radius: CGRectGetWidth(frame)/2 - 30.0, startAngle:startAngle, endAngle:endAngle, clockwise: true).CGPath
progressLayer.backgroundColor = UIColor.clearColor().CGColor
progressLayer.fillColor = UIColor.clearColor().CGColor
progressLayer.strokeColor = UIColor.blackColor().CGColor
progressLayer.lineWidth = 25.0
progressLayer.strokeStart = 0.0
progressLayer.strokeEnd = 0.0
gradientMaskLayer.mask = progressLayer
layer.addSublayer(gradientMaskLayer)
}
private func gradientMask() -> CAGradientLayer {
let gradientLayer = CAGradientLayer()
gradientLayer.frame = bounds
gradientLayer.locations = [1.0, 1.0]
let colorTop: AnyObject = UIColor(red: 255.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 1).CGColor
let colorBottom: AnyObject = UIColor(red: 255.0/255.0, green: 0.0/255.0, blue: 0.0/255.0, alpha: 0).CGColor
let arrayOfColors: [AnyObject] = [colorTop, colorBottom]
gradientLayer.colors = arrayOfColors
return gradientLayer
}
func hideProgressView() {
progressLayer.strokeEnd = 0.0
progressLayer.removeAllAnimations()
}
func secondsToHoursMinutesSeconds (seconds : Double) -> (Double, Double, Double) {
let (hr, minf) = modf (seconds / 3600)
let (min, secf) = modf (60 * minf)
return (hr, min, 60 * secf)
}
func animateProgressView(completionHandler: (() -> ())?) {
self.completionHandler = completionHandler
progressLayer.strokeEnd = 0.0
var temps = sharedDefaults!.objectForKey("roueCounter") as? Double
println(temps)
let animation = CABasicAnimation(keyPath: "strokeEnd")
animation.fromValue = CGFloat(0.0)
animation.toValue = CGFloat(1)
animation.duration = temps!
animation.delegate = self
animation.removedOnCompletion = false
animation.additive = true
animation.fillMode = kCAFillModeForwards
progressLayer.addAnimation(animation, forKey: "strokeEnd")
}
override func animationDidStop(anim: CAAnimation!, finished flag: Bool) {
completionHandler?()
completionHandler = nil
}
}
