Convert NSValue back to CGPoint

I made an NSMutableArray like this storing a bunch of CGPoints

    safeZonePoints = [NSMutableArray array];
    [safeZonePoints addObject:[NSValue valueWithCGPoint:CGPointMake(234, 160)]];
    [safeZonePoints addObject:[NSValue valueWithCGPoint:CGPointMake(284, 210)]];
    [safeZonePoints addObject:[NSValue valueWithCGPoint:CGPointMake(334, 160)]];
    [safeZonePoints addObject:[NSValue valueWithCGPoint:CGPointMake(284, 10)]];
    [safeZonePoints addObject:[NSValue valueWithCGPoint:CGPointMake(234, 160)]];

Now I can get the NSValues from the array, but how do I convert an NSValue back to CGPoint?

Solution

  • Do something like this:

    NSValue *cgpointObj = [NSValue valueWithCGPoint:CGPointMake(234, 160)];
CGPoint loc = cgpointObj.pointValue;

    It should be enough to answer your question.
