Huh? It's been my understanding that all CFTypes bridge to NSObjects. CGPathRef
certainly does:
#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
@autoreleasepool {
CGPathRef path = CGPathCreateWithRect(CGRectMake(0, 1, 2, 3), NULL);
for (Class class = [(__bridge id)path class]; class != nil; class =
[class superclass]) {
NSLog(@"%@", NSStringFromClass(class));
}
CGPathRelease(path);
}
return 0;
}

Given this, I'd expect you could make it work with KVC by making the property
an id instead of a CGPathRef, and doing a bridge cast every time you want to
use it. Of course, overriding valueForKey: is probably cleaner though.
