I've been enjoying NSUserDefaults when going through the Hillegeass book.
I've decided to do a small app that has two colors it stores. I get these
colors from a colorwell via Preference Pane.
I have bounded the values of the wells to backGroundWell and lineWell in IB.
I have the appropriately named methods. I know my bindings are ok becuase if
I just return [NSColor whiteColor] instead of the data
from NSUserDefaults, they're yellow when I open the pane. so that's ok.
I am pretty sure I'm getting a null from the defaults because the wells are
black. I have no "blackColor" in my project. Already searched for that. ;)
What am I doing wrong? I thought that NSUserDefaults was pretty simple...
Below are my getters and setters.
-(NSColor*)backGroundWell
{
NSLog(@"called BGwell");
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSData* data = [defaults objectForKey:@"BGCOLOR"];
NSColor* newColor = [NSKeyedUnarchiver unarchiveObjectWithData:data];
NSLog(@"retrieved Color for BG is %@", newColor);
//NSLog(@"%@",[NSKeyedUnarchiver unarchiveObjectWithData:data]);
return [NSKeyedUnarchiver unarchiveObjectWithData:data];
}
-(NSColor*)lineWell
{
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSData* data = [defaults objectForKey:@"LINECOLOR"];
return [NSKeyedUnarchiver unarchiveObjectWithData:data];
}
-(void)setBackGroundWell: (NSColor*)newColor
{
NSLog(@"New Color is %@", newColor);
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSColor* color = [backGroundWell color];
NSData* colorData = [NSKeyedArchiver archivedDataWithRootObject:color];
[defaults setObject:colorData forKey:@"BGCOLOR"];
NSLog(@"changing background color");
}
-(void)setLineWell: (NSColor*)newColor
{
NSLog(@"New Color is %@", newColor);
NSUserDefaults* defaults = [NSUserDefaults standardUserDefaults];
NSData* colorData = [NSKeyedArchiver
archivedDataWithRootObject:[lineWell color] ];
[defaults setObject:colorData forKey:@"LINECOLOR"];
NSLog(@"changing line color");
}
-------
Below is my +(void) initialize method
+(void) initialize
{
NSMutableDictionary* defaultValues = [NSMutableDictionary dictionary];
NSData* backgroundColorData = [NSKeyedArchiver
archivedDataWithRootObject:[NSColor greenColor] ];
NSData* lineColorData = [NSKeyedArchiver
archivedDataWithRootObject:[NSColor whiteColor] ];
[defaultValues setObject:backgroundColorData forKey:@"BGCOLOR"];
[defaultValues setObject:lineColorData forKey:@"LINECOLOR"];
[[NSUserDefaults standardUserDefaults] registerDefaults:defaultValues];
NSLog(@"registered defaults %@", defaultValues);
}

If you can't be kind, at least have the decency to be vague.
