To build on the answer given by atbreuer11, you can convert your CGPoint to NSValue, store it in NSMutableArray and convert it back using the following:

//Convert CGPoint and Store it
CGPoint pointToConvert = CGPointMake(100.0f, 100.0f);
NSValue *valueToStore = [NSValue valueWithCGPoint:pointToConvert];
NSMutableArray *arrayToKeep =[NSMutableArray arrayWithObject:valueToStore];

Then restore it again:

CGPoint takeMeBack;
for (NSValue *valuetoGetBack in arrayToKeep) {
    takeMeBack = [valuetoGetBack CGPointValue];
    //do something with the CGPoint
}

That's probably the easiest way to do it. You can write a complete class and do all types of data manipulation, but I think it would be an overkill, unless you really have to.
