Ti.App.iOS.addEventListener("shortcutitemclick", function(e){
	Ti.API.info("shortcutitemclick Event Fired");
	Ti.API.info("event payload:" + JSON.stringify(e));

});

var btn3 = Ti.UI.createButton({

});
win.add(btn3);
btn3.addEventListener("click",function(){
	var appShortcuts = Ti.UI.iOS.createApplicationShortcuts();
	var shortcutItems = appShortcuts.listDynamicShortcuts();
	Ti.API.info("Dynamic App Shortcut count:" + shortcutItems.length);	
	Ti.API.info("Dynamic App Shortcut as JSON:" + JSON.stringify(shortcutItems));

	Ti.API.info("Static App Shortcut as JSON:" + JSON.stringify(shortcutItems));
});

var btn5 = Ti.UI.createButton({
	top: 10, height:45, title:"Dynamic Shortcut Exists?"
});
win.add(btn5);
btn5.addEventListener("click",function(){
	var appShortcuts = Ti.UI.iOS.createApplicationShortcuts();
	var exists = appShortcuts.dynamicShortcutExists({
		type:"contact_us"
	});		
	var msg = (exists) ? "Icon exists" : "Sorry isn't there";
	alert(msg);
});

var btn6 = Ti.UI.createButton({
	top: 10, height:45, title:"Remove All Dynamic Shortcuts"
});
win.add(btn6);
btn6.addEventListener("click",function(){
	var appShortcuts = Ti.UI.iOS.createApplicationShortcuts();
	appShortcuts.removeAllDynamicShortcuts();
});
