Answer 1

I haven’t tested it yet, so just give me some suggestions. Apple phones should support it. I don’t know whether you open it on WeChat or use a browser Yes, if you are on WeChat, you can test it in the browser (Safari) first.
Add a judgment for testing

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