ios - iAds 干扰 Swift 应用程序的功能

Question

自从我在我的问答应用程序中启用了 iAds 后，每次加载新问题时本应更改的背景不再更改。当我注释掉 canDisplayBannerAds 行时，它再次起作用。关于什么可能是错误的任何想法？

import UIKit
import iAd

class ViewController: UIViewController {

    @IBOutlet weak var funFactLabel: UILabel!

    @IBOutlet weak var funFactButton: UIButton!
    let factBook = FactBook()
    let colorWheel = ColorWheel()

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        funFactLabel.text = factBook.randomFact()
        self.canDisplayBannerAds = true
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func showFunFact() {
        let randomColor = colorWheel.randomColor()
        view.backgroundColor = randomColor
        funFactButton.tintColor = randomColor
        funFactLabel.text = factBook.randomFact()
    }

}

Answer 1

与其使用 view.backgroundColor = randomColor，不如使用 originalContentView.backgroundColor = randomColor

我是如何得到解决方案的:

originalContentView

和originalContentView说:

When a view controller enables banner ads, the system puts the view controller’s content view inside of a new content view that the system manages. This allows the system to dynamically resize the original content view when a banner ad is displayed, as well as managing the display of the banner ad itself. This property provides access to the original content view, rather than the containing view that manages banner ad display.
