在UIWebView中具有多选的HTML文件输入不适用于视频 [英] HTML file input with multi selection in UIWebView not working for videos

问题描述

我一直在使用UIWebView（Cordova）创建打包为本机iOS应用程序的上传表单时遇到问题。问题是当在允许多个选择的元素中选择视频时。与仅可以进行单一选择的情况不同，所选视频也不是压缩的。预处理并因此以某种方式受到限制。

I've been having issues with creating an upload form packaged as a native iOS app using UIWebView (Cordova). Problem is that when a video is selected in a element that allows multiple selection. Unlike when only single selection is possible, the selected videos are not "compressed" aka. preprocessed and thus restricted in some way.

当尝试使用FileReader读取从照片库中选择的此类视频时，onerror函数会从FileReader中抛出ProgressEvent 使用以下FileError，代码1表示NOT_FOUND_ERR。

When trying to read such a video selected from the photo library using FileReader, the onerror function throws a "ProgressEvent" from the "FileReader" with the following "FileError" with code "1" meaning "NOT_FOUND_ERR".

但它在普通的iOS Safari Web视图中工作正常。

However it works fine in a normal iOS Safari web view.

我已向Apple提交了错误报告。

I've submitted a bug report to Apple.

此问题听起来与earlier issue ，其中以相同方式选择的视频没有文件大小。

Also this issue sounds very similar to an earlier issue where a video selected the same way had zero filesize.

推荐答案

我发现只有解决方案是跳过iOS UIWebView的多重选项，这只是一个不幸的解决方法。

Only solution I've found is to skip the multiple option for iOS UIWebView, which is just an unfortunate workaround.
