问题 I have a web application written in Ruby on rails that uploads videos from the user to the server using a form (I actually use a jquery uploader that uploads direct to s3, but I dont think this is relevant).

问题 I have an IPA and would like to upload it with Application Loader . But when I click "Open package" in Application Loader, I cannot select the IPA file, it is greyed out.
