It is more of a complain than a question, though maybe someone has some good points on it. So basically if you want an ivar in your Objective-C class have accessor-methods you have to mention it 3 times

SomeClass* _ivar;
@property (nonatomic,retain/assign/copy) SomeClass* ivar;
@synthesize ivar = _ivar;

and maybe 4th time in dealloc method. So wouldn’t it be more convenient if the approach would be like Java-style annotations – in one place before the actual ivar declaration, just something like:

@property (nonatomic,retain,synthesize = ivar,dealloc) SomeClass* _ivar;

this also generates accessor methods, and dealloc – telling to dealloc the ivar in dealloc method.

    Actually you don’t have to declare ivar – they can be synthesized if you just declare property for them. This should synthesize name iVar for you: (not supported in legacy run-times though – so one of the reasons of this seemingly redundant syntax is for backward compatibility with legacy platforms)

    @interface MyClass : NSObject 
{
}

@property(copy) NSString *name;

@end

...
@synthesize name;

    In new XCode version (4.0 probably) you won’t need to use @synthesize as well – properties will be synthesized by default.

    So as you see objective-c develops to satisfy your wishes 🙂
