title: AppDelegate Access
body: <p>For the old version xcode/ios, I used:</p>
  
  <pre><code>appDelegate =(AppDelegate *)[[UIApplication sharedApplication] delegate];
  </code></pre>
  
  <p>to access AppDelegate</p>
  
  <pre><code>#import "AppDelegate.h"
  
  
   @property (nonatomic,retain) AppDelegate *appDelegate;
  
  
  
  #import &lt;UIKit/UIKit.h&gt;
  
  @interface AppDelegate : UIResponder &lt;UIApplicationDelegate&gt; {
  
  }
  @property (strong, nonatomic) UIWindow *window;
  
  
  @end
  
  //-----
  
  #import &lt;UIKit/UIKit.h&gt;
  
  #import "AppDelegate.h"
  @interface DetailController : UIViewController{
  }
    @property (nonatomic,retain) AppDelegate *appDelegate;
  
  
  
  @end
  </code></pre>
  
  <p>but in ios5 AppDelegate change from NSObject to UIRepsonder</p>
  
  <p>Is it possible to access the AppDelegate?</p>
  
  <p>Welcome ant comment</p>
