IOS Iphone版广告移动的类（封装好了，所有页面共用一个广告）

使用方法：

1：在viewDidAppear:方法中添加以下代码，共享广告，设置委托为self

- (void)viewDidAppear:(BOOL)animated{    #ifdef CONTRACTIONM_FREE_2_0_        BannerViewController *banner = [BannerViewController sharedBanner];        self.bannerViewController = banner;        banner.delegate = self;        banner.upOrDown = kUp;        [self.view addSubview:self.bannerViewController.view];#endif       [super viewDidAppear:animated];}

2:在委托方法中根据b的值 ，调整界面

#ifdef CONTRACTIONM_FREE_2_0_- (void)ADIsComing:(BOOL)b{    if (b == YES) {        if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {            self.settingsScrollView.frame = CGRectMake(0, 60, 320, 356);            self.settingsScrollView.contentOffset = CGPointMake(0, 50);            [self.settingsScrollView flashScrollIndicators];            [self.settingsScrollView setContentOffset:CGPointMake(0, 0) animated:YES];        }    }    else {        self.settingsScrollView.frame = CGRectMake(0, 0, 320, 416);    }}#endif

3：少了一步最最最重要的，我一直浪费了一天在这个上面，气死我啦，在页面跳转的时候把委托置为nil

-(void)viewWillDisappear:(BOOL)animated{    self.bannerViewController.delegate = nil;    [super viewWillDisappear:animated];}
