解决方案
我解决了它,同时环顾四周。我将以下代码添加到我的 viewController 类中。
var SH = UIScreen.mainScreen().bounds.height
let transition = SKTransition.fadeWithDuration(0)
var UIiAd: ADBannerView = ADBannerView()
override func viewWillAppear(animated: Bool) {
var BV = UIiAd.bounds.height
UIiAd.delegate = self
UIiAd.frame = CGRectMake(UIScreen.mainScreen().bounds.width / 4.6, SH + BV, 0, 0)
self.view.addSubview(UIiAd)
}
override func viewWillDisappear(animated: Bool) {
UIiAd.delegate = nil
UIiAd.removeFromSuperview()
}
func bannerViewDidLoadAd(banner: ADBannerView!) {
var BV = UIiAd.bounds.height
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(0.5) // Time it takes the animation to complete
UIiAd.alpha = 1 // Fade in the animation
UIView.commitAnimations()
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(0.5)
UIiAd.alpha = 0
UIView.commitAnimations()
}
func showBannerAd() {
UIiAd.hidden = false
var BV = UIiAd.bounds.height
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(0.5) // Time it takes the animation to complete
UIiAd.frame = CGRectMake(UIScreen.mainScreen().bounds.width / 4.6, SH - BV, 0, 0) // End position of the animation
UIView.commitAnimations()
}
func hideBannerAd() {
UIiAd.hidden = true
var BV = UIiAd.bounds.height
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(0.5) // Time it takes the animation to complete
UIiAd.frame = CGRectMake(UIScreen.mainScreen().bounds.width / 4.6, SH + BV, 0, 0) // End position of the animation
UIView.commitAnimations()
}
override func viewDidLoad() {
super.viewDidLoad()
self.UIiAd.hidden = true
self.UIiAd.alpha = 0
NSNotificationCenter.defaultCenter().addObserver(self, selector: "hideBannerAd", name: "hideadsID", object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "showBannerAd", name: "showadsID", object: nil)
//My other code
}
然后我将此代码添加到将显示广告的 scene.swift 文件中。这些函数放在类之外。
func showAds() {
NSNotificationCenter.defaultCenter().postNotificationName("showadsID", object: nil)
}
func hideAds() {
NSNotificationCenter.defaultCenter().postNotificationName("hideadsID", object: nil)
}
然后当我想展示广告时,我使用 showAds() 调用 gameOver() 中的函数。完美运行!
