title: Call Native ios function from js class
body: <p>I am working on a hybrid application using Phone gap and iOS. I am integrating google admobs into the app.I have a main view controller class where i have implemented google ads. I have created a GADbannner view and added it as a subview to the self.view. This way ads are visible on each page of the application. Below my ads I have a Cordova web view. Now I also have a javascript class in the www folder of the app.I want to hide this banner view from javascript class. How can I do this?</p>
  
  <p>Please find my code of Main View controller with ads integrated:</p>
  
  <pre><code>if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
  {
      self.webView.frame=CGRectMake(0, 90, 320, 370);
      bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
  }
      // for iphone
  else
  {
      self.webView.frame=CGRectMake(0, 50, 320, 410);
  
      NSLog(@"page co-ordinates are set");
      bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];
  }
  
  self.webView.contentMode=UIViewContentModeScaleAspectFill;
  
  bannerView_.adUnitID = MY_BANNER_UNIT_ID;
  bannerView_.rootViewController = self;
  [self.view addSubview:bannerView_];
  </code></pre>
