I am trying to figure out how to switch over from my banner view iAds to interstitial iAds in order to free up space for a tabbed controller. For some reason I am completely unable to find any resource for even getting started on these ads with swift.
Could anyone please give me some information on interstitial iAds with Swift and how I can implement them in a project.
Here is a relatively cleaner and easier to follow way to implement Interstitial Ads since this way doesn't require the use of NSNotificationCentre
import UIKit
import iAd
class ViewController: UIViewController, ADInterstitialAdDelegate {
var interstitialAd:ADInterstitialAd!
var interstitialAdView: UIView = UIView()
override func viewDidLoad() {
super.viewDidLoad()
loadInterstitialAd()
}
func loadInterstitialAd() {
interstitialAd = ADInterstitialAd()
interstitialAd.delegate = self
}
func interstitialAdWillLoad(interstitialAd: ADInterstitialAd!) {
}
func interstitialAdDidLoad(interstitialAd: ADInterstitialAd!) {
interstitialAdView = UIView()
interstitialAdView.frame = self.view.bounds
view.addSubview(interstitialAdView)
interstitialAd.presentInView(interstitialAdView)
UIViewController.prepareInterstitialAds()
}
func interstitialAdActionDidFinish(interstitialAd: ADInterstitialAd!) {
interstitialAdView.removeFromSuperview()
}
func interstitialAdActionShouldBegin(interstitialAd: ADInterstitialAd!, willLeaveApplication willLeave: Bool) -> Bool {
return true
}
func interstitialAd(interstitialAd: ADInterstitialAd!, didFailWithError error: NSError!) {
}
func interstitialAdDidUnload(interstitialAd: ADInterstitialAd!) {
interstitialAdView.removeFromSuperview()
}
And it may help if you put println("Function Name") in each function just to keep track of your Interstitial Ads process. If you have any questions and or a way to improve this block of code please leave a comment. Thank You
Here is how i use in my project
//adding iAd framework
import iAd
//conform iAd delegate
class ViewController: UIViewController,ADInterstitialAdDelegate
//create instance variable
var interstitial:ADInterstitialAd!
//default iAd interstitials does not provide close button so we need to create one manually
var placeHolderView:UIView!
var closeButton:UIButton!
override func viewDidLoad() {
super.viewDidLoad()
//iAD interstitial
NSNotificationCenter.defaultCenter().addObserver(self, selector: ("runAd:"), name:UIApplicationWillEnterForegroundNotification, object: nil)
}
//iAD interstitial
func runAd(notification:NSNotification){
var timer = NSTimer.scheduledTimerWithTimeInterval(3.0, target: self, selector: Selector("dislayiAdInterstitial"), userInfo: nil, repeats: false)
cycleInterstitial()
}
func cycleInterstitial(){
// Clean up the old interstitial...
// interstitial.delegate = nil;
// and create a new interstitial. We set the delegate so that we can be notified of when
interstitial = ADInterstitialAd()
interstitial.delegate = self;
}
func presentInterlude(){
// If the interstitial managed to load, then we'll present it now.
if (interstitial.loaded) {
placeHolderView = UIView(frame: self.view.frame)
self.view.addSubview(placeHolderView)
closeButton = UIButton(frame: CGRect(x: 270, y: 25, width: 25, height: 25))
closeButton.setBackgroundImage(UIImage(named: "error"), forState: UIControlState.Normal)
closeButton.addTarget(self, action: Selector("close"), forControlEvents: UIControlEvents.TouchDown)
self.view.addSubview(closeButton)
interstitial.presentInView(placeHolderView)
}
}
// iAd Delegate Mehtods
// When this method is invoked, the application should remove the view from the screen and tear it down.
// The content will be unloaded shortly after this method is called and no new content will be loaded in that view.
// This may occur either when the user dismisses the interstitial view via the dismiss button or
// if the content in the view has expired.
func interstitialAdDidUnload(interstitialAd: ADInterstitialAd!){
placeHolderView.removeFromSuperview()
closeButton.removeFromSuperview()
interstitial = nil
cycleInterstitial()
}
func interstitialAdActionDidFinish(_interstitialAd: ADInterstitialAd!){
placeHolderView.removeFromSuperview()
closeButton.removeFromSuperview()
interstitial = nil
println("called just before dismissing - action finished")
}
// This method will be invoked when an error has occurred attempting to get advertisement content.
// The ADError enum lists the possible error codes.
func interstitialAd(interstitialAd: ADInterstitialAd!,
didFailWithError error: NSError!){
cycleInterstitial()
}
//Load iAd interstitial
func dislayiAdInterstitial() {
//iAd interstitial
presentInterlude()
}
func close() {
placeHolderView.removeFromSuperview()
closeButton.removeFromSuperview()
interstitial = nil
}
I know this is old - but I just came across
override func prepareForSegue(segue: UIStoryboardSegue,
sender: AnyObject?) {
let destination = segue.destinationViewController
as UIViewController
destination.interstitialPresentationPolicy =
ADInterstitialPresentationPolicy.Automatic
}
If you add this to your app delegate, you'll avoid that 3 second delay suggested above.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
UIViewController.prepareInterstitialAds()
return true
}
