ios在两个视图控制器之间传递数据而没有segue？

Question

我想将数据从一个视图控制器传递到另一个视图控制器，该控制器不使用 segue.in firstviewcontroller 当按钮触摸（收藏夹）希望数据传递到作为 tabbarviewcontroller 一部分的 secondviewcontroller（favoriteviewcontroller）时。 我知道最好的解决方案可能是使用委托？但是我该怎么做呢？

Answer 1

- (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:^{

  }];

  }
