Hi,bobiscool
首先非常感谢这个组件。
我遇到的问题是,循环生成Shape对象。并绑定事件。当点击shape对象的时候 destroy() 当前对象。
但是，发现总会出现Cannot read property 'getChoosed' of undefined的错误:
thirdScriptError Cannot read property 'getChoosed' of undefined;at pages/orderconfirm/index page bindtap function TypeError: Cannot read property 'getChoosed' of undefined at WxDraw.getDetectedLayers (http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:4407:71) at http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:3624:35 at Array.forEach (<anonymous>) at http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:3620:32 at Array.forEach (<anonymous>) at eventBus.dispatch (http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:3617:24) at Shape.detect (http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:3839:22) at WxDraw.<anonymous> (http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:4307:18) at Array.forEach (<anonymous>) at WxDraw.tapDetect (http://127.0.0.1:50576/appservice/utils/wxdraw.min.js:4306:26)

烦请抽空debug下。Thx
