我已经在
swift中复制了
iAdSuite with Storyboards,并且iAd在所有视图控制器上都可以正常工作,除了当调用委托方法bannerViewDidLoadAd(banner：ADBannerView！)时,横幅视图不会立即出现.我必须旋转模拟器或转到另一个标签,以便它出现.
我认为这是Objective-C中Apple示例代码的一部分,我无法“翻译”为swift？这可能导致iAd一旦加载就不会异步显示…
+ (BannerViewManager *)sharedInstance
{
static BannerViewManager *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken,^{
sharedInstance = [[BannerViewManager alloc] init];
});
return sharedInstance;
}
这是我的BannerViewManager类,带有ADBannerViewDelegate方法.
class BannerViewManager: NSObject,ADBannerViewDelegate {
// MARK: - Shared instance
static let sharedInstance = BannerViewManager()
var bannerView: ADBannerView!
var bannerViewControllers: NSMutableSet!
override init() {
super.init()
bannerView = ADBannerView(adType: .Banner)
bannerViewControllers = NSMutableSet()
bannerView.delegate = self
}
func addBannerViewController(controller: BannerViewController) {
bannerViewControllers.addObject(controller)
}
func removeBannerViewController(controller: BannerViewController) {
bannerViewControllers.removeObject(controller)
}
// MARK: - Ad banner view delegate methods
func bannerViewDidLoadAd(banner: ADBannerView!) {
NSLog("bannerViewDidLoadAd")
for bannerViewController in bannerViewControllers {
(bannerViewController as! BannerViewController).updateLayout()
}
}
func bannerView(banner: ADBannerView!,didFailToReceiveAdWithError error: NSError!) {
NSLog("didFailToReceiveAdWithError %@",error);
for bannerViewController in bannerViewControllers {
(bannerViewController as! BannerViewController).updateLayout()
}
}
func bannerViewActionShouldBegin(banner: ADBannerView!,willLeaveApplication willLeave: Bool) -> Bool {
NSNotificationCenter.defaultCenter().postNotificationName(BannerViewActionWillBegin,object: self)
return true
}
func bannerViewActionDidFinish(banner: ADBannerView!) {
NSNotificationCenter.defaultCenter().postNotificationName(BannerViewActionDidFinish,object: self)
}
}
编辑
我已设法使用this post on SO将上面的Objective-C代码转换为swift但我仍然遇到同样的问题. iAd一旦加载就不会出现.必须对视图进行某种更改才能实现,无论是旋转设备还是点击另一个选项卡等等……
所以现在我的sharedInstance看起来像这样：
static var sharedInstance: BannerViewManager {
struct Static {
static var onceToken: dispatch_once_t = 0
static var instance: BannerViewManager? = nil
}
dispatch_once(&Static.onceToken) {
Static.instance = BannerViewManager()
}
return Static.instance!
}
