Brand new to Iphone development,
My app loads but then it crashes right away, in the console I get this reason:
reason: '[<MyViewController 0x6939d60> setValue:forUndefinedKey:]:this class is not key value coding-compliant for the key delegate.'

Here's my IBOutlet References (i think):
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet MyViewController *viewController;
I can post some of my other source, but I'm not quite sure what would be relevant to this error, What does it mean?
Open up your XIB in IB and look at the MyViewController's links. There will be an inbound link to "delegate" that you need to delete.
Your view controller shouldn't be marked IBOutlet probably. Didn't it give you a stacktrace -- with the file and line# of the code that's having this issue?
What are you doing with the ViewController outlet? Did you connect that to something in IB?
Make sure your outlets are connected properly in IB - I've had this error when I change the name of an IBOutlet, but forget to change the connection in IB to the new IBOutlet (it's still trying to connect to the old variable name)

I am learning how to make iPhone apps in the simulator but my app crashes as soon as it launches in the simulator. Also, there are no errors and no warnings when I compile the source code.
Here is a copy of the console logs -

terminate called after throwing an instance of 'NSException'
I have tried and tried and can't seem to fix this problem. I will appreciate any help.
Your app is trying to load a file called LoginView.xib, and failing to. Seems like this file is referenced from your MainWindow.xib (or whichever is your main nib file as defined in your application plist). Check that this file exists, is copied to the bundle (in the copy resources build phase). If that's the case you can try cleaning the project, restarting xCode and trying again (I had this problem occasionally, for no apparent reason when switching between iPhone/iPad targets).
After adding a new searchbar on the RootViewController.xib, and connecting it with the FileOwner, the App will crash. It reports the stack when crash:

Well I don't know what you want us to tell you more then your error is already telling you.
Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: '-[UIViewController
_loadViewFromNibNamed:bundle:] loaded the "RootViewController" nib but
the view outlet was not set.'
That is that you forgot to connect your view outlet of your RootViewController so it does not know what to load. The RootViewController of your MainWindow is the first thing that's going to be loaded, if it does not know what view it should display it will give you the above error.
I have a very simple window based app, i am simply putting a navigation view controller as window's root view controller and it's crashing. This is the only thing i changed in the template project:
#interface AppDelegate : NSObject <UIApplicationDelegate> {
UINavigationController *navigationController;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
navigationController = [[UINavigationController alloc] init];
[[self window] setRootViewController:navigationController];
[self.window makeKeyAndVisible];
return YES;
}
It crashes saying:

Looks like you have a connection to a former existing UINavigationController IBOutlet in one of your nib files.
Start with MainWindow.xib and check for such a connection.
I had this problem occurring on the simulator only, but on the device it was working fine.
I tried cleaning the project, restarting Xcode, debugging, emptying the simulator data, the whole works.
In the end it was resolved by uninstalling the app from the simulator and reinstalling it. No idea why that worked, but it solved it!
I am trying to run the Apple's Scrolling Sample Code, but I get following Error:

terminate called after throwing an instance of 'NSException'
The weird thing is, that I can't find those connections in the MainWindow.xib (The only xib file). The Outlets are properly connected to the AppDelegate and MyViewController classes.
The Runtime cannot find a way to create an instance of the classes "ScrollingAppDelegate" and "ScrollingViewController", which are serialized in the xib file. So it defaults to UICustomObject, which you don't have either.
Are you sure those classes exist in your source file(s) and that they are compiled correctly (i.e., part of the "Compile" build phase)?
Also check the spelling and the capitalization of the classes. It has to match between the xib files and the source files.
If something is wrong, there could be a yellow warning dot in the xib file (bottom-right). Click it for more info.
Finally, the sample code is marked as iOS4+. Do you have iOS 4 on your device?
I have a navigation controller app. I created a RootViewController class with Xib file. In that xib file I had table view and nothing more else. Toolbar and buttons on the toolbar I created in program way. Table view had datasourse and delegate File Owner.
I deleted this xib file, and created a new one with previous name. Created it like viewBased xib file and then I dropped down to it table view, toolbar, two buttons on toolbar. Add outlets on them. Saved it all. Clear all targets. Build all. And Run. Application crashes on start! Anyone know where may be the problem? Thanx!

Your view controller lost connection for view outlet, you need to restore it in IB (as you do with all outlets)
