如何为iAd创建全局引用并在多个Viewcontrollers中实现 [英] How to create a global reference for iAd and implement in multiple Viewcontrollers

问题描述

我每个都有5个ViewControllers，我必须显示iAd，所以我必须在每个ViewControllers中实现iAd代码。而不是如果我在AppDelegate中创建公共代码集意味着我只需要在需要iAd显示的地方调用该代码。

I'm having 5 ViewControllers in each of that i have to display iAd,so that i have to implement iAd code in each ViewControllers. Instead of that if i create set of common code in AppDelegate means i can just call that code wherever i need iAd to be displayed.

如果有人实施了这个iAd概念意味着帮助我摆脱这个问题。在此先感谢。

If anyone has implemented this iAd concept means help me to get out of this issue. Thanks in Advance.

推荐答案

只需在APP委托中创建一个指向iAD的指针。

Just create a Pointer to iAD in APP delegate.

.h：

@property (strong, nonatomic) ADBannerView *UIiAD;

.m：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    UIiAD = [[ADBannerView alloc] init];
    return YES;
} 

然后在你的ViewControllers中执行以下操作：

Then in your ViewControllers do this:

.h：

@property (strong, nonatomic) ADBannerView *UIiAD;

.m：

- (AppDelegate *) appdelegate {
    return (AppDelegate *)[[UIApplication sharedApplication] delegate];
}

- (void) viewWillAppear:(BOOL)animated {
    UIiAD = [[self appdelegate] UIiAD];
    UIiAD.delegate=self;
   // CODE to correct the layout
}

- (void) viewWillDisappear:(BOOL)animated{
    UIiAD.delegate=nil;
    UIiAD=nil;
    [UIiAD removeFromSuperview];
}

为所有视图控制器执行此操作，并使用适当的代码重新设计布局！

Do this for all the view controllers with appropriate code to redesign the layout!
