Is it possible to previously load a UIViewController in iOs
===

in my iPhone application, i am using Unifeye mobileviewcontroller classes including EAGLView and metaio sdk. When I load this viewcontroller camera view will be activated along with this some of the metaio class functions also get called. In effect, it is taking so much of time to load the view controller. And also if I try to navigate to another view from Unifeye viewcontroller and coming back for sometimes, the app is crashing. 
So, I just wondering like, is there any way to load the viewcontroller in the background or at the beginning when the app opens. I am not sure. Please share your ideas if there is any possible to ways to make the loading quicker.
