我正在为我的所有视图创建此通用基本代码,它会创建一个横跨我所有网页的广告栏。我刚刚提供了一些代码来自Question的最佳答案,我无法解释为什么它不起作用。我试图这样做,如果adBanner没有加载我的标签伸展并占用该空间。 如果这很明显,我很抱歉,但我是新手。 这是我的代码
import Foundation
import UIKit
import iAd
class dayPicker: UIViewController , ADBannerViewDelegate{
var UIiAd: ADBannerView = ADBannerView()
var SH = UIScreen.mainScreen().bounds.height
var AH = CGFloat()
@IBOutlet var constOne: NSLayoutConstraint!
@IBOutlet var constTwo: NSLayoutConstraint!
func appdelegate() -> AppDelegate {
return UIApplication.sharedApplication().delegate as! AppDelegate
}
override func viewWillDisappear(animated: Bool) {
UIiAd.delegate = nil
UIiAd.removeFromSuperview()
}
func bannerViewDidLoadAd(banner: ADBannerView!) {
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(1)
UIiAd.alpha = 1
AH = 50
UIView.commitAnimations()
self.constOne.constant == 58
self.constTwo.constant == 58
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(1)
UIiAd.alpha = 0
AH = 0
UIView.commitAnimations()
self.constOne.constant == 8
self.constTwo.constant == 8
}
override func viewWillAppear(animated: Bool) {
UIiAd.delegate = self
UIiAd = self.appdelegate().UIiAd
UIiAd.frame = CGRectMake(0, SH - AH , 0, 0)
self.view.addSubview(UIiAd)
}
}
答案 0 :(得分:2)
您在分配时给予==
而不是=。
