device-orientation

问题 I am making my first steps coding with JavaScript and playing with Three.js. I am experimenting with this example from threejs.org :http://threejs.org/examples/#misc_controls_deviceorientation and this is the code that they have: (function() { "use strict"; window.addEventListener('load', function() { var container, camera, scene, renderer, controls, geometry, mesh; var animate = function(){ window.requestAnimationFrame( animate ); controls.update(); renderer.render(scene, camera); };

问题 I have an iPhone 6s Plus, and I have an app that supports both Portrait and Landscape orientations. When I rotate my device and read the property mainViewController.traitCollection.horizontalSizeClass - it always equals UIUserInterfaceSizeClassCompact . Many sources like this: https://forums.developer.apple.com/thread/17085 or this: http://useyourloaf.com/blog/size-classes/ tell that all 5.5-inch iPhones have Regular horizontal size class in the landscape orientation, but my device doesn't!!!
