Not sure how difficult this would be to add, but it would be nice if I could send an e-mail message containing a link of an existing map to a user and that user could click the link to open the ArcGIS for iOS application and have that particular map load. Of course the user would have to already have an account and be signed in at arcgis.com (?).
You have probably seen where other applications handle this through custom URL schemes. The URL might be something like arcgis://www.arcgis.com/map1. Some examples of custom URL schemes can be seen here.
This does not seem to work unless I am doing something wrong.
I figured out that the id which appears on arcgis.com is the <itemid>. I sent the link to myself, formatted as you suggested. I tried sending the link from arcgis for iOS and from MS Outlook. When I tap the link, the iPhone switches to the arcgis application but does not load the map, instead the old map stays loaded. I tried this with several maps, same result. I tried signing in to arcgis.com, then tap the link, same behavior.
In arcgis.com, the webmap is set to share with "Everyone". I sent you a link from ArcGIS/iOS with a map that is set to share with everyone. On my iPhone the link opens ArcGIS for iOS but leaves the previously opened map as the current map (not loading the linked map). Thanks for any help.
