How to push viewcontroller ( view controller )?

Question

Memory management is a very important issue in iPhone. So I am asking a very general question. There are two ways to call a the viewController of another class.

Way 1:

AnotherClassViewController *viewController = [[[AnotherClassViewController alloc] initWithNibName:@"AnotherClassView" bundle:nil] autorelease];

[self.navigationController pushViewController:viewController animated:YES];

Way 2:

    #import "AnotherClassViewController.h"

    @interface ThisClassViewController : UIViewController{

      AnotherClassViewController *myViewController;

    }

    @property (nonatomic, retain) AnotherClassViewController *myViewController;

    @end

    @implementation ThisClassViewController

    @synthesize myViewController;

    - (void) pushAnotherViewController{

    if(self.myViewController == nil){

    AnotherClassViewController *tempViewController = [[AnotherClassViewController alloc] initWithNibName:@"AnotherClassView" bundle:nil];

    self.myViewController = tempViewController;

    [tempViewController release];
    }
    [self.navigationController pushViewController:myViewController animated:YES];
    }

- (void)dealloc{
self.myViewController = nil;
}
@end

So the obvious question is, which is the best way to call the viewController of other class ? Way1 or Way2?

Suggestions and comments are openly invited.

Answer 1

Hmm... To keep things simple, why not just:

MyViewController* viewController = [[MyViewController alloc] init];

[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
