Automatic iVars with @synthesize

Question

I understand that starting with iOS 4, there is now the ability to not declare iVars at all, and allow the compiler to automatically create them for you when you synthesize

Answer 1

In constrast, I do the following:

@interface SomeViewController : UIViewController

@property (nonatomic, copy) NSString *someString;

@end

and then

@implementation SomeViewController

@synthesize someString;

- (void)dealloc
{
    [someString release], someString = nil;
    self.someString = nil; // Needed?

    [super dealloc];
}

@end

Note: At some point Apple will enable synthesize-by-default which will no longer require the @synthesize directive.
