We want to choose files (pdf, png, doc, ppt etc...) from our mobile device and upload it to a third party. We tried wx.chooseMedia, but it only supports images and videos, as well as wx.chooseMessageFile, which lets users choose files from their chat history.
Is there a way to choose documents from the mobile storage (iOS or Android)?
Maybe you should kown more about the rules of IOS. IOS don't support upload common file from mobile disk. So all applications can't provide solutions with uploading file. The api "wx.chooseMessageFile" only provide limited method to do this.
