Well, it appears that I need to convert either an NSNumber or an
NSString to a CGFloat, rather than an int:
- (void)drawInRect:(NSRect)rect angle:(CGFloat)angle
There don't appear to be any methods in either NSNumber or NSString to
do this....

I'd read that dictionaries and plists were particular in the types
they accept, but I was looking at page 201 of Hillegass (3rd
edition), which shows:
- (void)setInteger:(int)value forKey:(NSString *)defaultName
and
- (int)integerForKey:(NSString *)defaultName
and blindly followed.... Apple's NSUserDefaults documentation shows:
- (void)setInteger:(NSInteger)value forKey:(NSString *)defaultName
which makes more sense. Must be a typo in the book?

Brad,
You can't store an int into a Dictionary or user defaults. For the
objects you can use, see here:
http://developer.apple.com/documentation/Cocoa/Conceptual/PropertyLists/Articles/AboutPropertyLists.html#/
/apple_ref/doc/uid/20001010
NSNumber and NSString should work.
Also, [ICNElementBarGradientAngleKey intValue] will try to turn the
key into a number, not get it's value. You want to use:
[[defaults objectForKey: ICNElementBarGradientAngleKey] intValue];

I'm having a hard time with what should be a simple task - storing
an integer for a gradient angle as a user default and then
updating the screen. When I quit the app and open it again, the
NSTextField shows the last value I set for the gradient, but with
the following code:
- (IBAction)changeElementBarGradientAngle:(id)sender {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSLog(@"gradient angle is %d", [elementBarGradientAngleTextField
intValue]);
[defaults setInteger:[elementBarGradientAngleTextField intValue]
forKey:ICNElementBarGradientAngleKey];
NSLog(@"Element bar angle is now: %d",
[ICNElementBarGradientAngleKey intValue]);
}
I get:
2008-08-29 18:42:10.627 Icon[35645:10b] gradient angle is 75
2008-08-29 18:42:10.628 Icon[35645:10b] Element bar angle is now: 0
I've also tried turning the int into an NSNumber object and using
defaults setObject: foKey: without success.
It seems as though I have to use:
[gradient drawInRect:[self bounds] angle:
[ICNElementBarGradientAngleKey intValue]];
turning ICNElementBarGradientAngleKey back into an int, which
makes me wonder, is setInteger in:
[defaults setInteger:[elementBarGradientAngleTextField intValue]
forKey:ICNElementBarGradientAngleKey];
meant to be used with an int, or an object, such as NSUInteger?
What am I doing wrong?
Thanks,
Brad
