旋转 iPad 和 AdMob 不再加载，就像 iAds
Rotate iPad and AdMob to not load again, like iAds
我正在我的应用程序中实施 iAd 和 AdMob 横幅广告。在 iPad 上，当设备旋转时，我遇到了一些奇怪的问题，特别是 AdMob。
使用 iAds 时，横幅会在设备旋转时保留在屏幕底部，不会重新加载广告。
然而，使用 AdMob，它会在设备旋转时重新加载横幅，即使我使用的是相同的代码。
我正在以编程方式创建 ADBannerView 和 GADBannerView。
iAd代码：
self.adBanner.hidden = NO;
self.adBanner = [[self appdelegate] adBanners];
self.adBanner.delegate = self;
if (IDIOM == IPAD)
{
NSLog(@"***This is the iPad****");
[self.adBanner setFrame:CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-80, 320, 50)];
[self.adBanner setTranslatesAutoresizingMaskIntoConstraints:NO];
[self.view addSubview:self.adBanner];
NSLayoutConstraint *myConstraint =[NSLayoutConstraint
constraintWithItem:self.adBanner
attribute:NSLayoutAttributeLeading
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeLeading
multiplier:1.0
constant:0];
[self.view addConstraint:myConstraint];
myConstraint =[NSLayoutConstraint constraintWithItem:self.adBanner
attribute:NSLayoutAttributeTrailing
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeTrailing
multiplier:1
constant:0];
[self.view addConstraint:myConstraint];
myConstraint =[NSLayoutConstraint constraintWithItem:self.adBanner
attribute:NSLayoutAttributeBottom
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeBottom
multiplier:1
constant:0];
[self.view addConstraint:myConstraint];
}
AdMob 代码如下。我正在 applicationDidFinishLaunchingWithOptions:
的 AppDelegate 中创建 GADBannerView
更新
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// other code
self.adBanners = [[ADBannerView alloc]init];
self.adBanners.hidden = YES;
self.adMobBanners = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
return YES;
}
在视图控制器中，当我创建 AdMob 时，我调用了创建 AdMob 的方法：
更新
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if (![[NSUserDefaults standardUserDefaults] boolForKey:@"IAPSuccessful"])
{
NSLog(@"View will appear and the IAP is not Successful");
[self sharedBanners];
}
else
{
NSLog(@"View will appear and the IAP IS Successful");
self.adBanner.hidden = YES;
self.adMobBannerView.hidden = YES;
}
}
- (void)sharedBanners
{
self.adMobBannerView = [[self appdelegate] adMobBanners];
self.adMobBannerView.rootViewController = self;
self.adMobBannerView.delegate = self;
self.adBanner = [[self appdelegate] adBanners];
self.adBanner.delegate = self;
}
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
[self displayiAdsOrNot];
}
- (void)adViewDidReceiveAd:(GADBannerView *)view
{
[self displayAdMobBannerOrNot];
}
- (CustomAppDelegate *)appdelegate
{
return (CustomAppDelegate *)[[UIApplication sharedApplication] delegate];
}
- (void)displayAdMobBannerOrNot
{
self.adBanner.hidden = YES;
self.adMobBannerView.hidden = NO;
self.adMobBannerView = [[self appdelegate] adMobBanners];
self.adMobBannerView.rootViewController = self;
self.adMobBannerView.delegate = self;
if (IDIOM == IPAD) {
[self.adMobBannerView setFrame:CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-80, 320, 50)];
self.adMobBannerView.adUnitID = @"MYUNIT";
// [self.adMobBannerView setFrame:CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-80, CGSizeFromGADAdSize(kGADAdSizeFullBanner).width, 50)];
GADRequest *request = [GADRequest request];
[self.adMobBannerView loadRequest:request];
[self.adMobBannerView setTranslatesAutoresizingMaskIntoConstraints:NO];
[self.view addSubview:self.adMobBannerView];
NSLayoutConstraint *myConstraint =[NSLayoutConstraint
constraintWithItem:self.adMobBannerView
attribute:NSLayoutAttributeLeading
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeLeading
multiplier:1.0
constant:0];
[self.view addConstraint:myConstraint];
myConstraint =[NSLayoutConstraint constraintWithItem:self.adMobBannerView
attribute:NSLayoutAttributeTrailing
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeTrailing
multiplier:1

[self.view addConstraint:myConstraint];
myConstraint =[NSLayoutConstraint constraintWithItem:self.adMobBannerView
attribute:NSLayoutAttributeBottom
relatedBy:NSLayoutRelationEqual
toItem:self.view
attribute:NSLayoutAttributeBottom
multiplier:1
constant:0];
[self.view addConstraint:myConstraint];
}
}
**请注意，这不是方法的顺序。实际顺序是 AppDelegate、sharedBanner、displayAdMob、viewWillAppear，然后是委托方法。 **
限制的原因是我想将 ADBannerView 和 GADBannerView 固定到屏幕底部并尾随左侧。我的意思是，我希望它在屏幕底部从左边缘开始，在右边缘结束并穿过底部。
问题
加载 iAd 横幅时，它会在 iPad 屏幕的整个底部显示，从左侧开始到右侧结束。如果我旋转设备，iAd 横幅不会重新加载，它会继续与 iPad 一起旋转。但是，AdMob 横幅以纵向模式显示，但当我旋转时，它消失然后重新加载。
我尝试使用 Banner Ad Customization 作为常量，而不是 AdMob 横幅的明确尺寸。例如：
if (UIInterfaceOrientationLandscapeLeft)
{
NSLog(@"Left");
[self.adMobBannerView setFrame:CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-80, CGSizeFromGADAdSize(kGADAdSizeSmartBannerLandscape).width, 90)];
}
else if (UIInterfaceOrientationLandscapeRight)
{
NSLog(@"Right");
[self.adMobBannerView setFrame:CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-80, CGSizeFromGADAdSize(kGADAdSizeSmartBannerLandscape).width, 90)];
}
else if (UIInterfaceOrientationPortrait)
{
NSLog(@"Portraait");
[self.adMobBannerView setFrame:CGRectMake(0, [[UIScreen mainScreen] bounds].size.height-80, CGSizeFromGADAdSize(kGADAdSizeSmartBannerPortrait).width, 90)];
}
但问题依然存在。
更新问题的更新答案：
所以您的代码有很多问题。您似乎在 AppDelegate 和 ViewController 中创建了多个属性，并重复了一些相同的代码。我已经继续清理并完全重新实现了 iAd 和 AdMob 共享横幅。旋转设备时，我没有遇到 AdMob 横幅问题。此代码有利于 iAd，并且仅在 iAd 无法加载广告时显示 AdMob 横幅。试一试，如果您有任何问题，请告诉我。
