navBarHidden 질문

젤 먼저 앱 실행하면 첫화면이 category.js 로 연결 되어 있는데요

app.js 코드입니다.

// create tab group
var tabGroup = Ti.UI.createTabGroup();


// create base UI tab and root window
var win1 = Titanium.UI.createWindow({ navBarHidden : true, title : L(‘win1title’), url : ‘category.js’, backgroundImage : ‘images/bg.png’ });


var tab1 = Titanium.UI.createTab({ icon : ‘/images/city.png’, title : L(“tab1title”), window : win1 });


// create controls tab and root window 
var win2 = Titanium.UI.createWindow({ navBarHidden : true, url : ‘abc.js’, title : L(“win2″), backgroundColor : ‘#fff’, });


var tab2 = Titanium.UI.createTab({ icon : ‘/images/pricetag.png’, title : L(“win2″), window : win2 });


// create controls tab and root window 
var win3 = Titanium.UI.createWindow({ navBarHidden : true, url : ‘favorite.js’, title : L(“win3″), backgroundColor : ‘#fff’, });
var tab3 = Titanium.UI.createTab({ icon : ‘/images/heart.png’, title : L(“win3″), window : win3 });


// create controls tab and root window
var win4 = Titanium.UI.createWindow({ navBarHidden : true, url : ‘settings.js’, title : L(“win4″), backgroundColor : ‘#fff’, });
var tab4 = Titanium.UI.createTab({ icon : ‘/images/settings.png’, title : L(“win4″), window : win4 });


// add tabs 
tabGroup.addTab(tab1); 
tabGroup.addTab(tab2);
tabGroup.addTab(tab3);
tabGroup.addTab(tab4);


tabGroup.open();

제가 원하는 결과는 category 페이지의 title bar 를 숨기고 싶습니다.
