• 当前 Bug 的表现（可附上截图）

• 小程序内嵌 web-view 和 普通的 webview

• jssdk 调用 chooseImage ，选择相册图片，没有回调（success 与 fail 都没有）

• 拍照可以，但选择不可以

• 机型是 iphone 5s IOS10.3.3

• 预期表现

可以选择图片

function wechatImageHandler() {     let wx = window.wx;     return new Promise((resolve, reject) => {         let config = {             debug: false,             jsApiList: ['chooseImage', 'getLocalImgData'],             appId: WECHAT_SIGN.appId,             nonceStr: WECHAT_SIGN.nonceStr,             signature: WECHAT_SIGN.signature,             timestamp: WECHAT_SIGN.timestamp,         };           wx.config(config);         wx.ready(() => {             alert("choose");             wx.chooseImage({                 count: 1, // 默认9                 sizeType: ['compressed'], // 可以指定是原图还是压缩图，默认二者都有                 sourceType: ["album", "camera"], // 可以指定来源是相册还是相机，默认二者都有                 success: function (tempFilePaths) {                     alert("chooseSuccess");                     let localId = tempFilePaths.localIds[0];                     wx.getLocalImgData({                         localId: localId,                         success: function (res) {                             alert("getSuccess");                             let base64SplitArray = res.localData.split(",");                             // 微信 sdk 转换出来的 base64 格式是 jgp，此处做个兼容                             base64SplitArray[0] = base64SplitArray[0].replace("image/jgp", "image/jpeg");                             let base64String = base64SplitArray.join(",");                               resolve(base64String);                         },                         fail: function (res) {                             reject();                         }                     });                 },                 fail(res) {                     alert("fail")                 }             });         });     }); }
