So, I figured out how to pull NSUserDefaults using a settings bundle. But I am trying to do it without a bundle. I just want to save a variable called "theLevel" at a defined point. Then call that variable at the launch (or awakeFromNib) of the application. Can anyone help me with this?

Alright, so I am able to store the value (converted from an int to a string.) It gets saved in my applications preference folder in "com.yourcompany.ChainAttraction.plist" But I am having problems reading that value?

Here is the code I am trying to use to save and load.

Code: 
-(void)saveToUserDefaults:(NSString*)levelString
{
	NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];

	if (standardUserDefaults) {
		[standardUserDefaults setObject:levelString forKey:@"highlevel"];
		[standardUserDefaults synchronize];
	}
}

-(NSString*)retrieveFromUserDefaults
{
	NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
	NSString *val = nil;
	
	if (standardUserDefaults) 
		val = [standardUserDefaults objectForKey:@"highlevel"];
	
	return val;
}

I modified the code found at http://www.cocoadev.com/index.pl?NSUserDefaults

GOT IT GOT IT! I don't know why that code was going through the trouble of the if statement...anywho.

Simlpy use
Code: 
NSString *val = [standardUserDefaults objectForKey:@"theKey"];
to pull the value.
