How do I call method in current view controller of tabbar controller?
<pre><code>@interface MyAppDelegate : NSObject &lt;UIApplicationDelegate&gt; {
    UIWindow *window;
    UITabBarController *tabBarCtrl; 
}
@end

@interface FirstViewController : UIViewController {
}
-(void)myMethod;
@end
</code></pre>

<p>I want to call myMethod in FirstViewControlle.m from MyAppDelegate.m.
I tried this.</p>

<pre><code>[self.tabBarCtrl.selectedViewController myMethod];
</code></pre>

<p>Compiler says "UIViewController may not respond to myMethod".
How do I call FirstViewController's method?</p>
