Opened old project in Xcode 6 and found issue that background is not transparent in presented view controller. I have used solution in the topic below and it worked so far in ios7. iOS : ModalView with background transparent?
Please advice how to deal with iOS 8.
Try setting the modalPresentationStyle property of the presented view controller to the new UIModalPresentationOverCurrentContext constant e.g.
[_modalViewController setModalPresentationStyle:UIModalPresentationOverCurrentContext]
