IPhone - encoding and decoding NSValue

Question

So, I read here about SO that I can encode CGLayerRef in NSValue using

NSValue *myCopy = [[NSValue alloc] initWithBytes:&myLayer objCType:@encode(CGLayerRef)]; 

but how do I recreate a CGLayerRef from myCopy?

thanks

Answer 1

This should work:

 CGLayerRef giveMeBackTheLayer; [myCopy getValue:&giveMeBackTheLayer];
