Save and load text color - objective-c

Question

I looked and looked and looked for this and when i finally find something it does not work. I am trying to save and load text color that the user selects. Here is my save button:
-(IBAction)save123456 {
NSData *colorData = [NSKeyedArchiver archivedDataWithRootObject:textview];
[[NSUserDefaults standardUserDefaults] setObject:colorData forKey:#"myColor"];
}
And here is my load:
-(IBAction)load123456 {
NSData *colorData = [[NSUserDefaults standardUserDefaults] objectForKey:#"myColor"];
UIColor *color = [NSKeyedUnarchiver unarchiveObjectWithData:colorData];
}
My text view is textview if that helps. Also i am linking everything via tuchupinside so let me know if i should change anything.
Also if anyone knows how to save text font that the user selects would also be helpful. Thanks so much!!

Well , you could save the RGB of the color. And the font-name of the font.
So when you're saving , store these values for font: font.fontName , font.pointSize
and RGB of the color. Here you can see how to get the RGB of a UIColor object.
These are all NSString and float values so you shouldn't have any problem in saving them.
- (NSString *) pahtForFile:(NSString*) filename
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
return [documentsDirectory stringByAppendingPathComponent:filename];
}
- (void) save
{
//get RGB and fontName , fontSize like I explained above
NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
[dictionary setObject:fontName forKey:#"fontName"];
[dictionary setObject:[NSNumber numberWithFloat:fontSize] forKey:#"fontSize"];
[dictionary setObject:[NSNumber numberWithFloat:red] forKey:#"red"];
[dictionary setObject:[NSNumber numberWithFloat:green] forKey:#"green"];
[dictionary setObject:[NSNumber numberWithFloat:blue] forKey:#"blue"];
NSString *filepath = [self pathForFile:#"save.plist"];
[dictionary writeToFile:filepath atomically:TRUE];
}
- (void) load
{
float red,green,blue,fontSize;
NSString *fontName;
NSDictionary *dictionary = [NSDictionary dictionaryWithContentsOfFile:[self pahtForFile:#"save.plist"]];
red = [[dictionary objectForKey:#"red"] floatValue];
green = [[dictionary objectForKey:#"green"] floatValue];
blue = [[dictionary objectForKey:#"blue"] floatValue];
fontSize = [[dictionary objectForKey:#"fontSize"] floatValue];
fontName = [dictionary objectForKey:#"fontName"];
//now rebuild color and font like this:
UIColor *color = [UIColor colorWithRed:red green:green blue:blue alpha:1];
UIFont *font = [UIFont fontWithName:fontName size:fontSize];
}
Hope this helps.
BTW: If you find the answer useful , mark it as correct.
