登陆之前的缓冲界面实现

win2 出现，然后open事件，响应activityIndicator，然后过一段事件后启动win1

js代码：

// Ti.UI.backgroundColor = ‘white‘;

var win1 = Ti.UI.createWindow({

  backgroundColor: ‘blue‘

});

var win2 = Ti.UI.createWindow({

  backgroundColor: ‘yellow‘,

  fullscreen: true

});

var style;

if (Ti.Platform.name === ‘iPhone OS‘){

  style = Ti.UI.iPhone.ActivityIndicatorStyle.DARK;

}

else {

  style = Ti.UI.ActivityIndicatorStyle.DARK;

}

var activityIndicator = Ti.UI.createActivityIndicator({

  color: ‘green‘,

  font: {fontFamily:‘Helvetica Neue‘, fontSize:26, fontWeight:‘bold‘},

  message: ‘Loading...‘,

  style:style,

  top:10,

  left:10,

  height:Ti.UI.SIZE,

  width:Ti.UI.SIZE

});

// The activity indicator must be added to a window or view for it to appear

win2.add(activityIndicator);

// eventListeners must always be loaded before the event is likely to fire

// hence, the open() method must be positioned before the window is opened

win2.addEventListener(‘open‘, function (e) {

  activityIndicator.show();

  // do some work that takes 6 seconds

  // ie. replace the following setTimeout block with your code

  // win1.open();

  setTimeout(function(){

    e.source.close();

    activityIndicator.hide();

    win1.open();

  }, 6000);

});

// win1.open();

win2.open();
