苹果手机使用JSAPI扫码功能提示scan err，安卓正常，什么情况？！？！

$('.saomiao').on('click', function() {

       dd.biz.util.scan({
            type: 'qrCode',//type为qrCode或者barCode
            onSuccess: function(data) {
            //onSuccess将在扫码成功之后回调
              /* data结构
                { 'text': String}
              */
              
            },
           onFail : function(err) {
           }
        });

    });

我这里的参数改成了 qrCode 为什么安卓可以而IOS无法打开相机扫码呢？

已解决：缓存问题太严重了，缓存原因，我禁止他缓存了，为什么缓存问题这么严重呢？

把相关的代码代码块贴一下：调用了哪个js-api，入参和返回错误码

-------------------------

2. $('.scan').on('click', function () {
3.     dd.biz.util.scan({
4.         type: String,//type为qrCode或者barCode
5.         onSuccess: function (data) {
6.             //onSuccess将在扫码成功之后回调
7.             /* data结构
8.                { 'text': String}
9.             */
10.             window.location.href = "?ma=" + data.text;
11.         },
12.         onFail: function (err) {
13.             alert("scan err");
14.         }
15.     });
16. });
17. 
    
18. dd.biz.util.scan 的入参接受'qrCode'或者'barCode' 要使用二维码的话改成
20. $('.scan').on('click', function () {
21.     dd.biz.util.scan({
22.         type: 'qrCode',
23.         onSuccess: function (data) {
24.             //onSuccess将在扫码成功之后回调
25.             /* data结构
26.                { 'text': String}
27.             */
28.             window.location.href = "?ma=" + data.text;
29.         },
30.         onFail: function (err) {
31.             alert("scan err");
32.         }
33.     });
34. });

钉钉自带的扫描在苹果下也可以用，微应用里使用JSAPI就不行，苹果手机权限也看了，全都放开着呢，为什么啊？！？
