我想不得不在窗口底部的应用程序中放置iAd横幅,并且应用程序的其余部分,UINavigationController和视图处于打开状态窗口的顶部。我已经尝试过并尝试使用我的数学和逻辑技能,但似乎无法让它们正确显示。一个视图控制器内的两个视图控制器,管理框架属性
iAd横幅显示在正确的位置,但NavigationController不显示。
//AppDelegate.h
AdViewController *adController;
UINavigationController *navController;
UIViewController *containerView;
//.m file didFinishLaunching...
//views and controllers already initialized
containerView.view.frame = [[UIScreen mainScreen]bounds];
[containerView.view addSubview self.adController.view];
[containerView.view addSubview self.navController.view];
//hard coded frame for an ADBannerView (loaded in .xib)
CGRect bannerFrame = self.adController.view.frame;
//sets the start point vertically by subtracting the
//banner height from the total height of the screen
//in this case, 480 - 50
bannerFrame.origin.y = [[UIScreen mainScreen]bounds].size.height - bannerFrame.size.height;
self.adController.view.frame = bannerFrame;
//returns a rectangle that takes the 20 px status bar into account
//this rectangle's y origin is at 20
CGRect appFrame = [[UIScreen mainScreen]applicationFrame];
//This CGRect is assuming the applicationFrame
CGRect navFrame = appFrame;
//subtract the banner height from the navFrame height
//takes 50 px off of the height
navFrame.size.height = navFrame.size.height - bannerFrame.size.height;
self.navController.view.frame = navFrame;
