Hi all, I've finally had to give up the relentless search for an answer to this question, as I just can't find anyone that's asked it before! So hope someone can provide some insight. I'll start by explaining what I can do, then compare that with what I can't figure out how to do. Suppose I have a custom VC called RootViewController. I...

I want to allow a pushed to set parentViewController's instance variables. For instance, VC1 (the parent) has a bunch of textfields and what not which are filled from VC2 (the child). VC2 is pushed onto the stack by VC1. I've tried doing like parentViewController.myString = "foo"; however since parentViewController is a UIViewController,...
I think one of my design problems is that I keep creating navigation objects when I should only have one UINavigationController and a delegate. Is that correct? I not as concerned from a style-preference, but the answer I am looking for is more about the a technical perspective and managing the navigation among several view controllers...
I have 4 UIViews inside of a main view controller view. All I need to be able to do is drag the views around the "screen". Is UIScrollView the best option for this, or is there a simpler way? ...
I found a strange behavior, and would like to be explained what assertion I am making that is wrong. In an AppDelegate class of a freshly created WindowBased project, I am adding a UIViewController to the window. I can do it two different ways: - with an IBOutlet. In IB, I simply instanced an UIViewController, set its class to TestView...
I'm having a problem getting my view to be sized properly when created via -loadView. It seems that my view frame is always (0, 0, 320, 460), even when the view/controller is nested inside a UINavigationController and/or UITabBarController. Is there a way to detect programmatically when my view controller is nested within these items, ...
How do I make a resolution-independent iPhone view controller that can stack it's subviews like the browser stacks HTML elements? Here's an example. One UILabel at the top that could contain 1-6 lines of text; two UIButtons in a row right below the label; the left button could have a short or long title. I want the buttons to appear at...
Just beginning with iPhone development i seem to miss something fundamental. In a View based application i'm adding programaticaly a UIView subclass in the ViewController implementation file and can set a value: - (void)viewDidLoad { [super viewDidLoad]; CGRect myRect = CGRectMake(20, 50, 250, 320); GraphView *graphView = [[Gr...
Hello users, I have implemented an app that shows a map with a lot of pins on it. If you push one pin you get on a second view that shows the data behind the pin. A button takes you back to the map. My problem is that by the third touch on a pin the program crashes with a EXC_BAD_ACCESS in this method: - (void) switchViews { if...

Hi I am a relatively new iPhone app developer so my knowledge is a little sketchy, so please forgive me if this is a bit of a trivial question. I have a navigation app which drills between table views by calling pushViewController on the navigationController object I have one particular section which pushes new view controllers sequen...
I have a simple UIViewController and a UISearchBar, when the view loads I want to have the search bar become the first responder right away so that the keyboard is showing and they can start typing their query right away. I tried doing it in viewWillAppear like below without any luck: - (void)viewWillAppear:(BOOL)animated { [product...
I've implemented UINavigationController in my iphone application as main navigation interface. When I need to add some new xib to my UINavigationController stack I have to write new method like this (example for ContactsView.xib): - (void) switchToContactsView { // lazy load if (self.contactsViewController == nil) { Con...
I have a view with several embedded UITextFields, this UIView is subordinated to a UIScrollView in IB. Each text field is supposed to invoke a method called updateText defined in the viewcontroller implementation file when the user is done editing the field. For some reason, the method updateText never gets invoked. Anyone have any id...
'lo all. I am in the ending portion of my app for the iPhone and found that I am in a section of the app where I want to give feedback about the status of some background process running (location manager accuracy) and want to place it in the lower left of the screen. This can tell a user how "sure" we are about the given search resu...
