Question

所以在iAd出现后调整视图大小时遇到问题，它阻塞了视图的底部部分。我可以从已经为横幅腾出空间开始，但这看起来不是很好，看起来像一个空的白色空间。我希望在显示时基于iAd更新视图，当它消失时，两个视图都以编程方式添加。这是一些代码

 func bannerViewDidLoadAd(banner: ADBannerView!) {
    self.bannerView1.hidden = false
    print("BANNERVIEWSHOWN")     
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    self.bannerView1.hidden = true
    print("BANNERVIEWHIDDEN")


}

在viewdidload（）

中

    bannerView1.translatesAutoresizingMaskIntoConstraints = false
    bannerView1.delegate = self
    bannerView1.hidden = true





    self.pageMenu = CAPSPageMenu(viewControllers: controllerArray, frame: CGRectMake(0.0, 0.0, self.view.frame.width, self.view.frame.height), pageMenuOptions: parameters)


    pageMenu!.delegate = self



    self.view.addSubview(self.pageMenu!.view)

     self.view.addSubview(bannerView1)



    let viewsDictionary = ["bannerView": bannerView1]
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[bannerView]|", options: [], metrics: nil, views: viewsDictionary))
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[bannerView]|", options: [], metrics: nil, views: viewsDictionary))

我将如何制作它，以便它根据iAd增长和缩小？我知道如果是使用界面构建器制作高度约束我可以玩，但不是......

使用约束调整大小的最简单方法：

    // Setup our BannerView
    bannerView = ADBannerView(adType: .Banner)
    bannerView.frame = CGRectMake(0,0,bannerView.frame.width,bannerView.frame.height)
    bannerView.translatesAutoresizingMaskIntoConstraints = false
    bannerView.delegate = self
    bannerView.hidden = true

    view.addSubview(bannerView)

    let viewsDictionary = ["bannerView": bannerView]
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[bannerView]|", options: [], metrics: nil, views: viewsDictionary))
    view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|[bannerView]", options: [], metrics: nil, views: viewsDictionary))
