If I understood your question correctly, you want to prevent user to interact with your view till your loading process is finished. You can set Views userInteractionEnabled property for that. When you go for loading show at that moment set self.view.userInteractionEnabled = NO and after when your process is finished self.view.userInteractionEnabled = YES so this way you can prevent user to interact anywhere on your view while process is undergoing. Hope it helps.
