默认方向

<iphone>
  <orientations device="iphone">
    <orientation>Ti.UI.PORTRAIT</orientation>
  </orientations>
  <orientations device="ipad">
    <orientation>Ti.UI.PORTRAIT</orientation>
    <orientation>Ti.UI.UPSIDE_PORTRAIT</orientation>
    <orientation>Ti.UI.LANDSCAPE_LEFT</orientation>
    <orientation>Ti.UI.LANDSCAPE_RIGHT</orientation>
  </orientations>
</iphone>

运行时刻的真机方向检测

Ti.Gesture.isLandscape = function (orient) {
  orient = orient || Ti.UI.orientation;
  return orient == Ti.UI.LANDSCAPE_LEFT || orient == Ti.UI.LANDSCAPE_RIGHT;
};
 
Ti.Gesture.isPortrait = function (orient) {
  orient = orient || Ti.UI.orientation;
  return orient == Ti.UI.PORTRAIT || orient == Ti.UI.UPSIDE_PORTRAIT;
};

改变方向

Ti.Gesture.addEventListener('orientationchange',function (e) {
  // Put your handling code here
});

Ti.Gesture.addEventListener('orientationchange',function (ev) {
  if (Ti.Gesture.isLandscape(ev.orientation)) {
    // Update your UI for landscape orientation
  } else {
    // Update your UI for portrait orientation
  }
});

用程序改变方向

改变全局方向

Ti.UI.orientation = Ti.UI.PORTRAIT;

限制

var win = Ti.UI.createWindow({
    width: '100%',height: '100%',orientationModes: [
        Titanium.UI.LANDSCAPE_LEFT,Titanium.UI.LANDSCAPE_RIGHT
    ]
});

Ti.UI.currentWindow.orientationModes = [
    Titanium.UI.LANDSCAPE_LEFT,Titanium.UI.LANDSCAPE_RIGHT
];
