iAd插页式广告的自定义转换

Question

我想将ADInterstitialAds视为常规的UIView,以便在使用时获得一些灵活性.

例如,默认的插页式转换是slide up from the bottom of the screen.我不喜欢那样.是否可以首先将alpha值修改为0,然后将其更改为1？

另一个例子是在全屏添加前面有不同的UIView少量时间,即只是在转换过程中ADInterstitialAd？ADInterstitialAds往往是视图层次结构中最顶层的视图.如果我设法将ADInterstitialAds视为常规的UIView,我想我可以做到这一点.有关如何实现这一目标的任何建议？

Answer 1

您可以只设置 alpha 值的动画AdBannerView即可达到您想要的效果：

import iAd

private var bannerView: AdBannerView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Create your banner view however you want, and add it to your UI.
    bannerView = AdBannerView()
    bannerView.alpha = 0
    addSubview(bannerView)
}

// When you want to show the ad, animate the alpha.
private func animateInAd(appearing: Bool) {
    UIView.animateWithDuration(1.0) [weak self] {
        self?.bannerView.alpha = appearing ? 1 : 0
    }
}

这是展示bannerView 的另一种方式。当广告向上滑动完成后，您可以删除广告顶部的视图：

import iAd

private var coverView: UIView!
private var bannerView: AdBannerView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Create your banner view however you want, and add it to your UI.
    bannerView = AdBannerView()   
    addSubview(bannerView)

    // Create the cover view however you want, and add it above the banner view.
    coverView = UIView()
    addSubview(coverView)
}

private func animateInAd(appearing: Bool) {
    let hideAdPosition = view.frame.size.height        
    let showAdPosition = hideAdPosition - bannerView.frame.size.height

    UIView.animateWithDuration(1.0, animations: [weak self] {
        self?.bannerView.frame.origin.y = appearing ? showAdPosition : hideAdPosition
    }) { [weak self] success in
        self?.animateCover(appearing: !appearing)
    }
}

private func animateCover(appearing: Bool) {
    UIView.animateWithDuration(1.0) [weak self] {
        self?.coverView.alpha = appearing ? 1 : 0
    }
}

编辑：

至于ADInterstitialAds，它们似乎继承NSObject并具有您需要调用才能呈现它们的显式方法（presentInView:和presentFromViewController:）。因此，没有公共 API 来控制这些广告的呈现方式（这可能是故意这样做的，以便 Apple 可以保证向用户展示广告）。
