I have got the who view controller working well, but I need to change it so that it works in one of two ways: Either it is an abstract class which you must subclass and provider the implementation for a specific method which the controller will call...
Can anyone explain why it's not possible to create your own view controller hierarchies using UIKit on the iPhone? Let me explain: when creating applications using a complex view hierarchy and navigation logic, it's a good idea to have certain views controlled by a dedicated view controller. These controllers can have their own subcontr...

What is the best approach to implement tabs that look like web applications on the iPhone, like the screenshot below (notice the "Checkin-Info-Friends" tabs)? These are not part of the UIKit standard library, but seems to be very common lately. I've spent considerable time developing applications for the iPhone, but not developing contr...
I'm gussying up a Cocoa-Touch UI composed of basically two view hierarchies. Users need to drag objects from one (hierarchyA) INTO the other (hierarchyB). The problem I'm having is with the layering of these views, especially as they're being dragged. I don't know of a way to allow parts of hierarchyB be layered below a UIView from hiera...
Hi, I've found many tutorials on switching views on the iPhone but none that quite match my needs. I wonder if you can help. I'm looking to have an initial view, A and on a button press unload A and switch to view B. I've seen the following, but I have reasons why I don't want to do it that way: Using a navigation controller - Once v...

I have a simple UIViewController that uses a XIB for its interface. As such, the interface simply comprises a UIView, a UIActivityIndicator and a UILabel. I have the sizing constraints in Interface Builder set to keep the activity indicator and the label centred when the view rotates. The UIViewController is set to return YES for portr...
I have an app that uses various view controllers as tabs. I'm in the process of saving the custom tab order when the app shuts down. I'm trying to find a generic identifier for my various view controllers without having to add an attribute to each controller (which my backup plan). I would think, similar to UILabels, that maybe view con...

I'm trying to build an iPhone application that has two subviews in the main window. Each view has its own UIViewController subclass associated with it. Also, within each controller's implementation, I've added the following method: -(BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { ret...
I have multiple views which make the same NSURLRequest/NSURLConnection request. Ideally, in order to get some code reuse, I'd like to have some sort of a "proxy" which does all the underlying work of creating/executing the (asynchronous) request/connection, setting up all the delegate methods, etc., so I don't have to copy all those NSUR...
