I'm quite new in ios programming so sorry if I ask a dumb questin.
I want to develop an application for ipad using ios 7.1.
My problem: I used popoover presentation from storyboard to link a button to a view controller. I gave a custom class for the view controller that will be poppedover. But initially I want to set its layout alpha value and afterwards to make an animation. I did something like this:
self.view.alpha = 0.2;
self.popoverPresentationController.containerView.alpha = 0.2;
But I'm getting an error when I use the second line: [Popover popoverPresentationController]: unrecognized selector sent to instance...
So how can I change my popover alpha value at runtime? Thank you :)
