推荐答案

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
    {
    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
        // Custom initialization
    self.title = @"First View Controller";

    // this defines the back button leading BACK TO THIS controller
    UIBarButtonItem *backBarButtonItem = [[UIBarButtonItem alloc]
      initWithTitle:@"Back"
      style:UIBarButtonItemStyleBordered
      target:nil
      action:nil];
    self.navigationItem.backBarButtonItem = backBarButtonItem;
    [backBarButtonItem release];
    }
    return self;
}
