IONIC屏幕方向锁定

如果希望阻止app在设备旋转时发生横屏，可以使用这个插件：

cordova plugin add cordova-plugin-screen-orientation

// set to either landscape

screen.lockOrientation('landscape');

// allow user rotate

screen.unlockOrientation();

window.addEventListener("orientationchange", function()

{

console.log('Orientation changed to ' + screen.orientation);

});
