Question

目前我用它来编码加载iAD横幅。

- (void)viewDidLoad
{
    [super viewDidLoad];

    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
    CGRect adFrame = adView.frame;
    adFrame.origin.y = self.view.frame.size.height;
    adView.frame = adFrame;

    [adView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];

    [self.view addSubview:adView];
    adView.delegate=self;

    self.bannerIsVisible=NO;

}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
    if (!self.bannerIsVisible)
    {
        [UIView beginAnimations:@"animateAdBannerOn" context:NULL];

        CGRect adFrame = adView.frame;
        adFrame.origin.y = self.view.frame.size.height-adView.frame.size.height;
        adView.frame = adFrame;

        [UIView commitAnimations];
        self.bannerIsVisible = YES;
    }
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    if (self.bannerIsVisible)
    {
        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];

        CGRect adFrame = adView.frame;
        adFrame.origin.y = self.view.frame.size.height+adView.frame.size.height;
        adView.frame = adFrame;

        [UIView commitAnimations];
        self.bannerIsVisible = NO;
    }
}

问题是我想在设备方向改变时自动将iAD视图设置到视图的底部。我尝试了很多东西，但没有任何东西在起作用。

另外，为什么我必须使用通知中心来检查设备方向？ DidRotateToInterfaceOrientation似乎不起作用。

Answer 1

我可能已经理解了这个错误，但是如果你设置了以下内容：

[adView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin];

这应该意味着当你的视图变大/变小时（旋转时）它应该增加/减少'顶部'边距，因此应该坚持到底部。

我可能已经错误地理解了这一点。如果上述想法不起作用，你能提供当前正在发生的截图吗？

Answer 2

在viewDidLoad方法中尝试此操作：

CGRect adFrame = adView.frame;
adFrame.origin.y = self.view.frame.size.height-adView.frame.size.height;
adView.frame = adFrame;

无论设备类型如何，它都会将您的iAd设置为视图的底部。不要在委托方法中设置iAd的框架。

此解决方案适用于iOS 6

使用通知在视图控制器的viewDidLoad方法中侦听设备方向更改：

UIDevice *device = [UIDevice currentDevice];
[device beginGeneratingDeviceOrientationNotifications];
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self selector:@selector(orientationChanged:)name:UIDeviceOrientationDidChangeNotification object:device];

UIInterfaceOrientation destOrientation = self.interfaceOrientation;

然后在viewController中使用if语句来监听更改，并在方向更改时重新定位广告横幅视图：

if (destOrientation == UIInterfaceOrientationPortrait || destOrientation == UIInterfaceOrientationPortraitUpsideDown) {

    ADBannerView *bannerView = (ADBannerView *)[self.view viewWithTag:615];
    CGRect myAdBanner = bnrAd.frame;
    myAdBanner.origin.x = 0;
    myAdBanner.origin.y = 410;
    bannerView.frame = myAdBanner;

} else {

    ADBannerView *bannerView = (ADBannerView *)[self.view viewWithTag:615];
    CGRect myAdBanner = bnrAd.frame;
    myAdBanner.origin.x = 0;
    myAdBanner.origin.y = 265;
    bannerView.frame = myAdBanner;
}

不要忘记调用方法将广告加载到您的视图中：

- (void) bannerViewDidLoadAd:(ADBannerView *)banner {
    bnrAd = _bannerView;
}

- (BOOL) bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave {
    return YES;
}

请参阅下面的代码，我在我的iPad App中使用此代码，需要支持iOS 6及更高版本：

您的.h文件中的

#import <iAd/iAd.h>

@interface MyViewController : UIViewController <ADBannerViewDelegate> {

    ADBannerView *bannerView;

    BOOL bannerIsVisible;

}

.m文件中的

- (void)viewDidLoad
{
    [super viewDidLoad];
    // detect device orientation change
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

    if (SYSTEM_VERSION_LESS_THAN(@"7.0")) {

        [[NSNotificationCenter defaultCenter]
         addObserver:self selector:@selector(orientationChanged:)
         name:UIDeviceOrientationDidChangeNotification
         object:[UIDevice currentDevice]];

    }

    [self showiAds];

}

- (void) showiAds{

    bannerView = [[ADBannerView alloc] initWithFrame:CGRectZero];

    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {

        UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

        if(orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight) {

            [bannerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth |UIViewAutoresizingFlexibleBottomMargin];

        } else {

            [bannerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin];

        }

    }

    if (SYSTEM_VERSION_LESS_THAN(@"7.0")) {

        [bannerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth |UIViewAutoresizingFlexibleBottomMargin];

    }

    bannerView.delegate = self;

    bannerView.hidden = YES;

    [self.view addSubview:bannerView];

    bannerIsVisible = NO;

}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
    NSLog(@"bannerViewDidLoadAd");

    if (!bannerIsVisible) {

        bannerView.hidden = NO;

        [UIView beginAnimations:@"animateAdBannerOn" context:NULL];

        // banner is invisible now and moved out of the screen on 50 px
        banner.frame = CGRectOffset(banner.frame, 0, self.view.frame.size.height - bannerView.frame.size.height);

        [UIView commitAnimations];

        bannerIsVisible = YES;

    }
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    NSLog(@"didFailToReceiveAdWithError : %@", [error localizedDescription]);

    if (bannerIsVisible) {

        [UIView beginAnimations:@"animateAdBannerOff" context:NULL];

        // Assumes the banner view is placed at the bottom of the screen.
        banner.frame = CGRectOffset(banner.frame, 0, banner.frame.size.height);

        [UIView commitAnimations];

        bannerIsVisible = NO;

    }

}

希望您理解上面的代码。祝你好运
