(My apologies for the long post) To jazz up my AQGridView, the attached code copies the selected cell into a UIView, then animates that view to expand to fill the screen, then have said view transform to look like a full screen cover animation. Feel free to reuse, but that’s not my problem. My problem is the animation for Landscape, which must be different. I wish to animate my cell view to the right half of the screen and expand to fill the right half of the screen (already accomplished) then have it do a y flip rotation across the screen to the left side. Anchor points at CGPointMake(0.5, 0.5); don’t work, and neither does setting the translate x value to half of the screen and back again, it just performs, then flies off the screen! HELP!!
EDIT: (The code is now working thanks to me not realizing that I had been adding the new UIView's to the self.navigationController.view property, so all it took was to render that and flip it, no translations needed!)
