cocos2d-JS 实现横竖屏显示提示图片效果 !!!!!

全局添加旋转屏幕帧听 :

初始化游戏场景时调用 : (因为全局帧听需要选择才会起作用，所以第一次需要手动添加一次提示旋转图)

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; Box-sizing: border-Box; font-family: 'Source Code Pro',monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0,136); Box-sizing: border-Box;">this</span>._checkOrientation()</code><ul class="pre-numbering" style="Box-sizing: border-Box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221,238);"><li style="Box-sizing: border-Box; padding: 0px 5px;">1</li></ul><ul class="pre-numbering" style="Box-sizing: border-Box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221,238);"><li style="Box-sizing: border-Box; padding: 0px 5px;">1</li></ul>

第一次初始化判断是不是竖屏创建一个 LayerColor 和所需提示旋转图片

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; Box-sizing: border-Box; font-family: 'Source Code Pro',monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">    _checkOrientation: function(){

            //cc<span class="hljs-preprocessor" style="color: rgb(68,68); Box-sizing: border-Box;">.pause</span>()
        }

        //}
