Xcode使iad粘到屏幕底部

Question

我怎样才能让iad的横幅总是在屏幕的底部，用户可以上下滚动，但添加将始终存在（屏幕底部）。这是我的代码，我使用的IAD：

ViewController.h

@interface ViewController : UIViewController <ADBannerViewDelegate> 

ViewController.m

// Method is called when the iAd is loaded. 
-(void)bannerViewDidLoadAd:(ADBannerView *)banner { 

    // Creates animation. 
    [UIView beginAnimations:nil context:nil]; 

    // Sets the duration of the animation to 1. 
    [UIView setAnimationDuration:1]; 

    // Sets the alpha to 1. 
     [banner setAlpha:1]; 

    // Performs animation. 
    [UIView commitAnimations]; 

} 

// Method is called when the iAd fails to load. 
-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error { 

    // Creates animation. 
    [UIView beginAnimations:nil context:nil]; 

    // Sets the duration of the animation to 1. 
    [UIView setAnimationDuration:1]; 

    // Sets the alpha to 0. 
     [banner setAlpha:0]; 

    // Performs animation. 
    [UIView commitAnimations]; 

}

添加到您的AppDelegate中的窗口，并把上述所有的意见那个横幅。即降低所有ViewController的横幅高度的高度。
