例如：
var image = new Image(); image.src=dataURLs;
image.src=''填的是一个dataurl，就是base64字符串的图片。然后在电脑和android上都可以显示，就是在ios上显示不成功。想问是怎么回事？谢谢了
闭关修行中......
base64
iPad（9.2）
Know what the problem is:
// 引用外部图片，需设置 crossOrigin 属性，否则 toDataURL 调用异常 // image.setAttribute('crossOrigin', 'anonymous'); // 不使用url图片时，一定要把上面这一行注释掉，否则canvas加载不出base64图片
I don’t know the specific reason, but you can consider downloading Safari to debug
