Orientation making simulator crash

[iSDK]

Hi, i am trying to add notifications for the orientation being changed, but whenever i implement the code the iphone simulator quits.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];

Do you have an orientationChanged: method? Note the colon on the end.

What does the crash message in the console say?

[iSDK]

I think the method is

- (void)orientationChanged: (id) sender
{
//my code
}

The crash message is the standard sig fault (bad exec, etc)

The crash message before the Stack: ( ... ) bit is probably helpful. Please post it.

If it's just a EXC_BAD_ACCESS then either your object that's getting the message was deallocated, or you're doing something bad inside your orientationChanged: method. Does that method even get run? Add a breakpoint or NSLog and find out.

[iSDK]

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) anOrientation
{
	printf("Is Portrait?: %s\n",
		   UIDeviceOrientationIsPortrait(anOrientation)
		   ? "Yes" : "No");
	printf("Is Landscape?: %s\n",
		   UIDeviceOrientationIsLandscape(anOrientation)
		   ? "Yes" : "No");
	return YES;
}
- (NSString *) orientationString
{
	switch ([[UIDevice currentDevice] orientation]) 
	{
		case UIDeviceOrientationUnknown: return @"Unknown";
		case UIDeviceOrientationPortrait: return @"Portrait";
		case UIDeviceOrientationPortraitUpsideDown: return @"Portrait Upside Down";
		case UIDeviceOrientationLandscapeLeft: return @"Landscape Left";
		case UIDeviceOrientationLandscapeRight: return @"Landscape Right";
		case UIDeviceOrientationFaceUp: return @"Face Up";
		case UIDeviceOrientationFaceDown: return @"Face Down";
		default: break;
	}
	return nil;
}
- (void) orientationChanged: (id) sender
{
	NSLog(@"Orientation changed to %@", [UIDevice currentDevice].orientationString);
	self.log = [NSMutableString string];
	[self doLog:[UIDevice currentDevice].orientationString];
}

[self doLog:[UIDevice currentDevice].orientationString];

That line looks crashworthy. I don't think UIDevice has a "orientationString" property. You probably meant [self orientationString] there if you're trying to call your orientationString method. I assume doLog: is another method you wrote in this class.
