我使用 Apple iAd Suite 演示代码中的代码来实现带有标签栏控制器的横幅广告。它一直运行良好，直到最近，当我注意到测试广告变得更加丰富多彩，而不仅仅是带有“测试广告”字样的黑色矩形。

但是，我现在看到，虽然横幅视图旋转正常，但完整的广告仅以横向显示。应用程序的其余部分可以正常旋转，但无论设备处于什么方向，完整的添加只会以横向显示。

我不明白如何控制这个。

这是代码：

#import "BannerViewController.h"

NSString * const BannerViewActionWillBegin = @"BannerViewActionWillBegin";
NSString * const BannerViewActionDidFinish = @"BannerViewActionDidFinish";

@implementation BannerViewController
{
    ADBannerView *_bannerView;
    UIViewController *_contentController;
}

- (id)initWithContentViewController:(UIViewController *)contentController
{
    self = [super init];
    if (self != nil) {
        _bannerView = [[ADBannerView alloc] init];
        _bannerView.delegate = self;
        _contentController = contentController;
    }
    return self;
}

- (void)loadView
{
    UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    [contentView addSubview:_bannerView];
    [self addChildViewController:_contentController];
    [contentView addSubview:_contentController.view];
    [_contentController didMoveToParentViewController:self];
    self.view = contentView;
}

- (void)viewDidUnload
{
    [super viewDidUnload];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return [_contentController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

- (void)viewDidLayoutSubviews
{
    if (UIInterfaceOrientationIsPortrait(self.interfaceOrientation)) {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
    } else {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
    }
    CGRect contentFrame = self.view.bounds;
    CGRect bannerFrame = _bannerView.frame;
    if (_bannerView.bannerLoaded) {
        contentFrame.size.height -= _bannerView.frame.size.height;
        bannerFrame.origin.y = contentFrame.size.height;
    } else {
        bannerFrame.origin.y = contentFrame.size.height;
    }
    _contentController.view.frame = contentFrame;
    _bannerView.frame = bannerFrame;
}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
    [UIView animateWithDuration:0.25 animations:^{
        [self.view setNeedsLayout];
        [self.view layoutIfNeeded];
    }];
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
    [UIView animateWithDuration:0.25 animations:^{
        [self.view setNeedsLayout];
        [self.view layoutIfNeeded];
    }];
}

- (BOOL)bannerViewActionShouldBegin:(ADBannerView *)banner willLeaveApplication:(BOOL)willLeave
{
    [[NSNotificationCenter defaultCenter] postNotificationName:BannerViewActionWillBegin object:self];
    return YES;
}

- (void)bannerViewActionDidFinish:(ADBannerView *)banner
{
    [[NSNotificationCenter defaultCenter] postNotificationName:BannerViewActionDidFinish object:self];
}

@end

在该shouldAutorotateToInterfaceOrientation:方法中，interfaceOrientation 是纵向的，并且评估为真。完整的广告仍以横向显示。

是什么原因造成的，我该如何控制它？

沙盒模式似乎只支持一种方向。
