UIWindow and UIView addSubview Question
Does the addSubview method actually load the view into the application or not? The reason I am asking is because I have two two views in my application.

Is it possible to have a sound play before/during the splash screen?
My app takes a few seconds to load and I have a splash screen. Once "viewDidLoad" I have a little sound play. I feel that the sound would be in better use if it started playing when the splash screen popped up. Is it possible to have a sound start before/during the splash screen? Here is my code: (under viewDidLoad) NSString *sound...

When that button is clicked I want to remove the current view, load a new one, open the image picker, get the selected picture, and display it in the view that I just loaded. I have read several documents that say UIImagePicker does not work in viewDidL...

I am working on an IPhone project where I set up some drawing parameters external to view.drawRect in a procedure called -(void) reset. I call this from the viewController.viewDidLoad method to get the parameters set before the drawing occurs.

iPhone SDK: viewDidLoad() sees an empty NSArray, but it's populated in a delegate method (MGTwitterEngine)
This is probably obvious, but I'm a bit of a newbie and have spent hours trying to figure this out. In viewDidLoad() I have a call to a function on an MGTwitterEngine object (custom object), with an input. If the request (to Twitter, in this case) is successful, it calls an appropriate delegate method. In viewDidLoad(), it's like thi...

How to keep an NSArray available to all methods when programming for the iPhone.
Hello. I am making an iPhone app that uses a few NSArrays. Right now I have to generate the arrays in each method. I know there has to be an more efficient way of doing this, like having the NSArrays created during initialization and then being available to all methods after that. The problem is, that when I create the NSArrays in th...

Iphone app development - How do I reload(?) views?
Okay, I'm working on a iPhone game. You start off on a menu screen, then select "New Game" or "High Scores". Let's select "New Game."

Here is the exact code: - (id)initWithNibName:(NSString *)ni...
Do I programatically add SubViews in ViewDidAppear, ViewDidLoad, ViewWillAppear, the constructor?
I'm trying to figure out from Apple's sketchy documentation which method is the best place to be initializing and adding my Views controls to the controller's view. With winforms it's fairly straightforward, as they're always initialized inside InitializeDesigner, called in the constructor. I'm trying to match the reliability of this pa...
