I\'m trying to build an application that is launched has a transparent background, in practice, showing only the objects in view (buttons, labels etc etc) but not the backgr
No. It's not possible using the official SDK. I'm interested to know why you would want to do this?
It might be possible, try setting the window background color to clear, as well as the view controller's view background color.
I say it might be possible because I've seen my home screen while using some apps, for example, the Facebook app sometimes shows it during a transition (it might be a bug on either Facebook or the OS).
Anyway, I'm pretty sure that kind of app would be rejected from the App Store, so be advised.
