Use Xamarin Forms and on iOS, how to check and open Word app when Open file by UrL?
Reference: https://docs.microsoft.com/en-us/office/client-developer/integration/integrate-with-office-from-ios-applications

This is my code, it isn't work:

Device.OpenUri(new Uri("ms-word:ofe|u|https://calibre-ebook.com/downloads/demos/demo.docx"));

Please help me!
Thanks!

What you are asking here can be done using a simple WebView in iOS:

First, create a custom WebView class that allows you to pick file uri:

public class CustomWebView : WebView

{

    public static readonly BindableProperty UriProperty = BindableProperty.Create(propertyName: "Uri",

            returnType: typeof(string),

            declaringType: typeof(CustomWebView),

            defaultValue: default(string));



    public string Uri

    {

        get { return (string)GetValue(UriProperty); }

        set { SetValue(UriProperty, value); }

    }



}

Then in ios make a renderer for the same and do something like this:

  [assembly: ExportRenderer (typeof(CustomWebView), typeof(CustomWebViewRenderer))]

  namespace DisplayPDF.iOS

 {

   public class CustomWebViewRenderer : ViewRenderer<CustomWebView, UIWebView>

  {

    protected override void OnElementChanged (ElementChangedEventArgs<CustomWebView> e)

    {

        base.OnElementChanged (e);



        if (Control == null) {

            SetNativeControl (new UIWebView ());

        }

        if (e.OldElement != null) {

            // Cleanup

        }

        if (e.NewElement != null) {

            var customWebView = Element as CustomWebView;

            string fileName = Path.Combine (NSBundle.MainBundle.BundlePath, string.Format ("Content/{0}", WebUtility.UrlEncode (customWebView.Uri)));

            Control.LoadRequest (new NSUrlRequest (new NSUrl (fileName, false)));

            Control.ScalesPageToFit = true;

          }

       }

   }

}

Then use the custom control like this:

 <local:CustomWebView Uri="FooPath" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" /> 

Where FooPath is the path for the doc file.

I have solution for my project, I try it:

If you only open file .docx on iOS, you could write code at Share Code of iOS:

1. 
   

   Check device of user has setup app (Word, Excel, PP, etc...)

   
   
   

   public static bool HasSetupAppDocument(string extension)
   
   {
   
       if (string.IsNullOrEmpty(extension))
   
           return false;
   
   
   
       // Device has setup app?
   
       var result = UIApplication.SharedApplication.CanOpenUrl(NSUrl.FromString($"{extension}"));
   
       return result;
   
   }
   
   

   
   

(Ex: extension is ms-word: or ms-excel: or ms-excel:

Reference: https://docs.microsoft.com/en-us/office/client-developer/integration/integrate-with-office-from-ios-applications#office-protocols)

Notes: Add source to Info.plist:

<key>LSApplicationQueriesSchemes</key>

<array>

     <string>ms-word</string>

     <string>ms-excel</string>

     <string>ms-powerpoint</string>

</array>

2. 
   

   At Class Dependencies, open file with URL:

   
   
   

   Device.OpenUri(new Uri($"{convertExtension}{url}"));

   
   

Note: url is link file share on Onedrive and Be sure that account Onedrive as same as account login Word app (if you had set security).

If file has mode Read-only, app Word will open file with mode Read-only.
