Take multiple pictures using Titanium/Appcelerator on iPhone

I am working on a small iPhone app using Titanium/Appcelerator. Now what I am trying to do is the following:

• Open the camera to take a picture
• Ask the user if he wants to add another picture (OptionDialog)
• Open the camera again
• {loop here}
• Put the images (saved l开发者_如何学运维ocally) into an array

I tried putting a OptionDialog into the success event of the camera, but it didn't work as expected.

maybe something like that.

 dialog.addEventListener('click',function(e){
      switch (e.index){
         case 1:
          takeAPicture();
         case default:
           ...          
      };
 });

function takeAPicture(){

  Titanium.Media.showCamera({
    success: function(evtSuccess) {
      dialog.show();    
    },
    ...
  });

};
Titanium.Media.takePicture();

what happened putting it into the success event? what exactly did you put into? i would put the

dialog.show();

into the success event too
