Just use NSPointerArray:
@implementation NSPointerFunctions (Additions)
static NSUInteger _PointerFunctionsCGPointStructSize(const void *item)
{
return sizeof(CGPoint);
}
+ (NSPointerFunctions *)pointerFunctionsForCGPoint;
{
NSPointerFunctions *aPointerFunctions = [NSPointerFunctions
pointerFunctionsWithOptions:(NSPointerFunctionsStructPersonality|NSPointerFunctionsMallocMemory|NSPointerFunctionsCopyIn)];
[aPointerFunctions setSizeFunction:&_PointerFunctionsCGPointStructSize];
return aPointerFunctions;
}
@end
@implementation NSPointerArray (Additions)
+ (id)pointPointerArray;
{
return [[[self alloc] initWithPointerFunctions:[NSPointerFunctions
pointerFunctionsForCGPoint]] autorelease];
}
- (CGPoint)pointAtIndex:(NSUInteger)theIndex;
{
return *(CGPoint *)[self pointerAtIndex:theIndex];
}
- (void)addPoint:(CGPoint)thePoint;
{
[self addPointer:&thePoint];
}
@end
