page 142 synthesize question

[Mike]

Hi Steve,

I noticed that the property and synthesize directives have been used in program 7.2. So I wasn't sure why a setTo method would be needed except that you can initialize both at the same time but then do you need to use property and synthesize?


Thanks
Mike

Mike,

You can only synthesize accessor methods for a single instance variable.  The setTo:over: method in Program 7-2 takes two arguments and seeks to set two instance variables; therefore, it can't be synthesized.

Cheers,
