Question

How do I set an instance’s property when that property is a CGRect. I want to do this:

CGRect rect = CGRectFromString(value);
[localClassObjectInstance setValue:rect forKey:key];

but the compiler doesn’t like the setValue; it says I’m sending CGRect to parameter of incompatible type ‘id’.

Thanks

You must transform a CGRect to NSValue (and viceversa):

NSValue *myValue = [NSValue valueWithCGRect:rect];

NSValue is an object (so it’s of type “id”).

Then you can get the CGRect back with:

CGRect myRect = [myValue CGRectValue];
