Encoding CGPoint struct with NSCoder

Question

How do you encode and decode a CGPoint struct using NSCoder?

Answer 1

To encode:

CGPoint point = /* point from somewhere */
NSValue *pointValue = [NSValue value:&point withObjCType:@encode(CGPoint)];
[coder encodeObject:pointValue forKey:@"point"];

To decode:

NSValue *decodedValue = [decoder decodeObjectForKey:@"point"];
CGPoint point;
[decodedValue getValue:&point];

Answer 2

Just an update for iOS developers. You can do the following in Cocoa Touch (but not in Cocoa):

[coder encodeCGPoint:myPoint forKey:@"myPoint"];
