canvas在IOS8中不兼容。画不出来。

var canvas=document.getElementById('myCanvas');
var ctx=canvas.getContext('2d');
ctx.fillStyle='#FF0000';
ctx.fillRect(0,0,80,100);

上面是我在w3c上面拷贝的,在ios8.1.2版本的苹果6上面,cavas画不出内容,求解决办法。

没测试过,就提点建议吧,苹果手机该是支持的,不知道你是在微信打开还是使用浏览器打开的,如果是在微信的话可以先在浏览器(Safari)中测试。
加个判断进行测试

if (canvas == null) {  
         //测试 
   } 

参考标准
