title: Adding a button and navigating between views
body: <p>1.) I need to add 2 buttons, one below another. My working so far is demonstrated below; It only shows one button, but how can i add another button with a different button image below this button ?</p>
  
  <p>2.) When the user clicks a button, i need to navigate to another screen. How can i do this ?
  I need the equivalent of the following objective-c code ?</p>
  
  <pre><code>View1 *view1 = [[View1 alloc] initWithNibName:@"View1" bundle:nil];
              [self.navigationController pushViewController:View1 animated:YES];
  </code></pre>
  
  <p>3.) How can i add a navigation Bar (equivalent to the navigation bar shown in iPhone)</p>
  
  <p>The code for the 1st question;</p>
  
  <pre><code>{
                  items:[
                      {
                          xtype:'button',
                          text: 'Submit',
                          ui:'confirm',
                          handler: function(){
                            var values = Ext.getCmp('contactForm').getValues();
  
                            Ext.Ajax.request({
  
                              url: 'http://loonghd.com/service/',
  
                              failure: function (response) {
   //do something
              },                              success: function (response) {
                                                                           // do something
                              }
  
                             });
                          }
                      }
                  ]
  
              }
  </code></pre>
