調整UINavigationController佈局問題

Question

我想在我的擴展UINavigationController中添加一個ADBannerView。 當旗幟負載我重新大小這樣的觀點：

CGRect contentFrame = [[UIScreen mainScreen] applicationFrame]; 
banner.currentContentSizeIdentifier = ADBannerContentSizeIdentifier320x50; 
bannerHeight = banner.bounds.size.height; 

self.view.frame = CGRectMake(self.view.bounds.origin.x, 
            (self.view.bounds.origin.y), 
            self.view.bounds.size.width, 
            contentFrame.size.height - (bannerHeight)); 

但UIView的是導航欄下部分牆根：here

任何想法有什麼不好？

感謝

self.view.frame = CGRectMake(self.view.bounds.origin.x, 
           (self.view.bounds.origin.y)+(bannerHeight), 
           self.view.bounds.size.width, 
           contentFrame.size.height - (bannerHeight));
