Properties declared as instance variables too?

Question

This code works:

    @interface StringStuff : NSObject {

    }
    @property (nonatomic, retain) NSString *String1;
    @property (nonatomic, retain) NSStri         


        

Answer 1

Legacy; it used to be (and still is on 32 bit Mac OS X targeted code) that the ivar declarations were required. That is no longer true on iOS, the simulator and 64 bit OS X.

Note that it is common to @synthesize iVar = iVar_; to prevent accidental direct access where self.iVar is really required.
