ios在兩個視圖控制器之間傳遞數據而沒有segue？

Question

我想將數據從一個視圖控制器傳遞給另一個視圖控制器，這些視圖控制器不通過segue.in firstviewcontroller互相連接，當按鈕觸摸（最喜歡）需要數據傳遞給屬於tabbarviewcontroller的secondviewcontroller（favoriteviewcontroller）時。 我知道最好的解決方案可能使用委託？但我該怎麼做？

- (IBAction)showFavouriteViewController:(UIButton *)sender { 
    //Create an instance of FavouriteViewController 
    FavouriteViewController *fVC = [self.storyboard instantiateViewControllerWithIdentifier:@"FavouriteViewController"]; 
    //Set public property of FavouriteViewController (these are the data you wanted to send) 
    fVC.favouriteArray = @[@"Apple", @"Orange"]; 
    //Show the FavouriteViewController 
    [self.navigationController showViewController:fVC sender:nil]; 
} 



- (IBAction)showFavouriteViewController:(UIButton *)sender { 
    //Create an instance of FavouriteViewController 
    FavouriteViewController *fVC = [self.storyboard instantiateViewControllerWithIdentifier:@"FavouriteViewController"]; 
    //Set public property of FavouriteViewController (these are the data you wanted to send) 
    fVC.favouriteArray = @[@"Apple", @"Orange"]; 
    //Show the FavouriteViewController 
    [self.navigationController pushViewController:fVC animated:YES]; 

    } 

- (IBAction)showFavouriteViewController:(UIButton *)sender { 
    //Create an instance of FavouriteViewController 
    FavouriteViewController *fVC = [self.storyboard instantiateViewControllerWithIdentifier:@"FavouriteViewController"]; 
    //Set public property of FavouriteViewController (these are the data you wanted to send) 
    fVC.favouriteArray = @[@"Apple", @"Orange"]; 

    [self presentViewController:fVC animated:YES completion:^{ 

    }]; 

    // OR 

    UINavigationController *nVC = [[UINavigationController alloc] initWithRootViewController:fVC]; 
    //Presnet 
    [self presentViewController:nVC animated:YES completion:^{ 

    }]; 

    }
