为什么我的钛金属应用程序进入无限循环，但在iPhone中可以正常工作？

var win=Ti.UI.currentWindow;

win.backgroundImage=\'goldmenubackground.jpg\';

var win_zipsearch=Ti.UI.createWindow({backgroundImage:\'goldmenubackground.jpg\'});
var win_search=Ti.UI.createWindow({backgroundImage:\'goldmenubackground.jpg\'});
var win_fav=Ti.UI.createWindow({backgroundImage:\'goldmenubackground.jpg\'});
var win_morerest=Ti.UI.createWindow({backgroundImage:\'goldmenubackground.jpg\'});

var tabgroup1=Ti.UI.createTabGroup();

var tab_nearby=Ti.UI.createTab({title:\'Near By\',window:win});
var tab_zipsearch=Ti.UI.createTab({title:\'Zip Search\',window:win_zipsearch});
var tab_search=Ti.UI.createTab({title:\'Search\',window:win_search});
var tab_fav=Ti.UI.createTab({title:\'My Favourites\',window:win_fav});


var tab_morerest=Ti.UI.createTab({title:\'More Restaurants\',window:win_morerest});

    tabgroup1.addTab(tab_nearby);
    tabgroup1.addTab(tab_zipsearch);
    tabgroup1.addTab(tab_search);
    tabgroup1.addTab(tab_fav);
    tabgroup1.addTab(tab_morerest);
    tabgroup1.open();
