iOS: disable snapshot from being taken when app backgrounded (for security reasons)

app.js

// by Blain Hamon
var win = Ti.UI.createWindow({
  backgroundColor : 'white',
  orientationModes : [Ti.UI.PORTRAIT]
});
win.open();

var label = Ti.UI.createLabel({
  text : 'No app event received. Make call while running app',
  textAlign : 'center',
  width : 'auto'
});
win.add(label);

Titanium.App.addEventListener('pause', function() {
// this will delete the Snapshots folder and create a file in its place 
// so that the folder cannot be recreated
  var snapFolder = Ti.Filesystem.getFile(Ti.Filesystem.applicationSupportDirectory,"../Caches/Snapshots");
  snapFolder.deleteDirectory(true);
  snapFolder.write("No Folder for you!");
  label.text = "App has been paused";
});

Titanium.App.addEventListener('resume', function(e) {
  label.text = "App has resumed";
});
