Yes, this is my implementation:
@implementation TextColorValueTransformer
+ (Class)transformedValueClass
{
return [NSColor class];
}
+ (BOOL)allowsReverseTransformation
{
return NO;
}
- (id)transformedValue:(id)value
{
BOOL theBoolean = [value boolValue];
if (theBoolean) {
return [NSColor blueColor];
}
return [NSColor blackColor];
}
@end
