Just a heads up:
Built my app with the iOS 9 Beta 4 SDK today. url.createInputStream() was giving a null result everytime, regardless of the url. Tried it with the JUCE demo, and got the same result in the HTTP section.
Turns out iOS 9 has introduced a new feature called App Transport Security that by default requires secure connections (https). You can read more about it here: http://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/
I'm not dealing with sensitive information. So instead of transitioning the relevant urls on my site to SSL, I added the following to info.plist:
<key>NSAppTransportSecurity</key> <dict> <!--Include to allow all connections--> <key>NSAllowsArbitraryLoads</key> <true/> </dict>
Which allows regular http connections. You also have the option of adding specific domains to be allowed, instead of all. Maybe provide this as an option in Introjucer?
