Automatically update iOS binary (IPA) from the app with objective-c codes

Actually I am wondering whether this solution only works for ad-hoc apps or I can use BetaBuilder to create a IPA for my final apps that should install on non jailbreak devices too?

Also is there a way that I call this URL from my app with objective-c codes so that app itself download the IPA file and install it on the device?

Answer 1

You can update app by providing link of app's new version only if you have generated ad-hoc or enterprise distribution build. Also your app can not download the new version on its own. You need to open browser with new version link and rest of the process will be handled by iOS.
