You can do quite a few things in iOS with building extensions.
Those are usually special kind of applications with an objective C class exposing some methods called by the system.
Does anyone know whether you can turn a Xojo made iOS app into such an extension app and it works?
This is something I am wondering about also. I just did a search here on the forum to see if this is possible and noticed that Christian asked this without anyone responding. So I figured a bump and joining in asking the same question might help surface it again - and maybe get an answer from someone who might know.
