UBableViewController下面的ADBannerView

问题描述

我想在UItableViewController中的tableView下面集成iAd横幅。目标是调整tableview的大小并添加到UIViewController的底部，在这种情况下是一个UITableViewController。我开始考虑adBannerView是一个UIView所以我编写了下面的代码和UIView，它工作，但当我尝试通过用ADBannerView替换它来发生同样的事情时，它不会发生。 ADBanner出现在正确的位置，但tableView调整大小丢失。

I want to integrate the iAd banner below a tableView in a UItableViewController. the goal is to resize the tableview and add to the bottom of the UIViewController, a UITableViewController in this case. I started considering that the adBannerView is a UIView so I wrote the code below and for a UIView, and it worked, but when I try to make same thing happen by replacing it with a ADBannerView it doesn't happen. The ADBanner appeared in the correct position but the tableView resizing is lost.

有人可以尝试了解原因并帮助我找到更好的解决方案。没有使用footerView是否可行？

can somebody try to understand why and help me out to find a better solution. is it feasible without using the footerView?

这里是代码。目前是Utils类中的静态方法。接下来我将在另一个上下文中使用它，但您应该可以轻松地自己测试它

here the code. At the moment is a static method within a Utils class. Next I'll use it in another context, but you should easily able to test it by yourself

class ViewControllerUtils {
    class func showBanner<C:UIViewController where C:ADBannerViewDelegate> ( viewController:C)  {

        println("*** showBanner isLandscape:\(UIDevice.currentDevice().orientation.isLandscape)")

        // you don't care about it for the moment.
        var bannerHeight:CGFloat = 50.0
        if UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Pad{
            bannerHeight = 66.0
        } else if UIDevice.currentDevice().orientation.isLandscape {
            bannerHeight = 32.0
        }
        println("bannerHeight: \(bannerHeight)")

        // created a local variable in order to update the original frame
        var viewFrame  = viewController.view.frame

        UIView.animateWithDuration(1.0, animations: { () -> Void in
                        println("viewFrame \(viewFrame)")

            viewFrame.size.height -= bannerHeight
            viewController.view.frame = viewFrame
            println("viewFrame \(viewFrame)")

            }) { (ended:Bool) -> Void in

                var x = CGPoint(x: viewFrame.origin.x, y: viewFrame.origin.y + viewFrame.size.height)
                var bannerFrame = CGRect(origin:  x, size: CGSize(width: viewFrame.size.width, height: bannerHeight))

                var container = UIView(frame: bannerFrame)
                container.backgroundColor = UIColor.redColor()

                //without this line it works like expected.
                //with it tableview resizing is not applied anymore
                container.addSubview(ADBannerView(frame: CGRect(origin:  CGPointZero, size: CGSize(width: viewFrame.size.width, height: bannerHeight))))

                viewController.view.superview?.addSubview(container)
        }

    }

}

推荐答案

如果您需要的只是TableViewController底部的横幅，您可以使用预建行为，将 canDisplayBannerAds 设置为 true ，如下所示：

If all you need is the banner at the bottom of the TableViewController, you can just use the prebuilt behavior, setting canDisplayBannerAds to true like this:

import UIKit
import iAd

class MainViewController: UITableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        self.canDisplayBannerAds = true
    }

}
