I have a TableViewController with a protoptype cell. It's populated with Labels and ImageViews from a .plist with an Array of Dictionaries. How can I pass this data to the detail View? The detail view is a UIViewController subclass. I've tried with methods from different tutorials but I just can't find the right combination to make it work.

问题 I hope this is a simple question. I need to intercept didAddSubview , but will I need to subclass the UIView in order to override that method? The UIView that I want to override is the UIViewController 's view property, so I just want to know how to go about working with this. Thanks! 回答1: From Apple UIView documentation (see Methods to Override ): When subclassing UIView, there are only a handful of methods you should override and many methods that you might override depending on your needs.

问题 I'm trying to create a custom UIView that will, when tapped, segue to a new view controller. I'd like to do this programmatically rather than in Interface Builder. How do I get a reference to the destination view controller when I'm doing this? I assume I don't just create one and set it as the next view or something, so where does the reference come from? Since when it's done in the storyboard you simply choose where you want the segue to have as the destination, it's not an issue there,

问题 I need to adjust several views in the event that a user visits my app while in a phone call. Is there a best practice for being notified of this? Thanks! 回答1: You want to check the statusBarFrame property of the shared UIApplication instance. Take a look at Resize for in-call status bar?. 来源： https://stackoverflow.com/questions/2618799/how-do-i-get-notified-when-a-user-opens-my-iphone-app-while-in-a-phone-call

问题 I don't want to fade in and fade out like most common solution for the uiview animation. I would like to have the uiview resize to small until it disappear and comes back the same way. Another way to say it is having a camera pointing closely at the table with all the object in it (UIView) and camera backs up and the more it backs up the smaller the table gets. Which is why i titled which is mainly my app the whole uiview sinks into the water and floats back up. Hopefully i'll find a tutorial

问题 I've successfully set up my app flow logic and everything seems to be working fine except the login. I would like to keep the users logged in so when the app is reopened the profile screen is the first to show. Right now I have code.. override func viewDidAppear(animated: Bool) { var currentUser = PFUser.currentUser() println(currentUser.objectId as String) if currentUser != nil { self.performSegueWithIdentifier("loginsuccess", sender: nil) } else { // Show the signup or login screen } } It

问题 I'm trying to build transition for card flip & zoom. I've made its model in Origami - Movie (less that 1Mb) As you can see there are 3 transforms applied at the same time: 1. moving center of the view to the centre of the screen 2. scaling 3. 3D rotte We can divide animation on equal 2 phases: Phase 1: Button scales, moves and rotates on the side (PI/2 radians). At the end of Phase 1 button disappears. Phase 2: toView (my modal view) rotates (from -PI/2 to 0 radians), scales up to the normal
