title: Native IOS App recieve data from webbrowser javascript
body: <p>I have a app with storyboard and navigationViewController. On one page, i have a webView object, which contains a webshop. In this view i had to hide the top bar, because i want to use this place for my own html5-bar. </p>
  
  <p>Now my question. Is it possible to trigger the (hidden) backbutton via javascript from webView? </p>
  
  <h2>E D I T</h2>
  
  <p>I tried this code from the solution-link</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      [[self navigationController] setNavigationBarHidden:YES animated:YES];
      [self.browser loadRequest: [NSURLRequest requestWithURL: [NSURL URLWithString:@"http://www.mywebshop.com/mobile/"]]];
  }
  
  
  -(void) webView:(UIWebView *)browser shouldStartLoadWithRequest:(NSURLRequest *)inRequest navigationType:(UIWebViewNavigationType)inType {
      if ( [[[inRequest URL] scheme] isEqualToString:@"callback"] ) {
  
          NSLog(@"Catched Succesfull");
      }
      NSLog(@"NOT Catched");
  }
  </code></pre>
  
  <p>But it catches not the event. There is no logging. Did i misunderstood something?</p>
