Converting a CGPoint to NSValue

Question

In CABasicAnimation.fromValue I want to convert a CGPoint to a "class" so I used NSValue valueWithPoint but in device mode or simulator one is not working... need to use NSMakePoint or CGPointMake if in device or simulator.

Answer 1

There is a UIKit addition to NSValue that defines a function

+ (NSValue *)valueWithCGPoint:(CGPoint)point

See iPhone doc

Answer 2

@ashcatch 's answer is very helpful, but consider that those methods from addition copy values, when native NSValue methods store pointers! Here is my code checking it:

CGPoint point = CGPointMake(2, 4);
NSValue *val = [NSValue valueWithCGPoint:point];
point.x = 10;
CGPoint newPoint = [val CGPointValue];

here newPoint.x = 2; point.x = 10

---

CGPoint point = CGPointMake(2, 4);
NSValue *val = [NSValue valueWithPointer:&point];
point.x = 10;
CGPoint *newPoint = [val pointerValue];

here newPoint.x = 10; point.x = 10
