Cannot Archive Array of Values Representing CGPoints

I have converted CGPoint To NSValue and开发者_开发技巧 put all the resulting values in q NSArray but when I use [NSKeyedArchiver archiveRootObject:ArrayName toFile:PointArrayFile]; it gives me error.

So what's the problem?

You don't say what problem you're seeing but in general you're probably better off using NSStringFromCGPoint and CFPointFromString to store and retrieve the points.
