ios - 将对象添加到 NSMutableArray 全局变量？

Question

I have a UITableView Controller and when a row is selected, I want to add that row's recipe to NSMutableArray addedRecipesArray which is a property of AppDelegate. 但是，根据我设置的 NSLogs，我可以看出实际上并没有将任何食谱添加到 addedRecipesArray 中。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    recipe = [recipesArray objectAtIndex:indexPath.row];
    NSLog(@"You have added %@ to the shoppingList", recipe.recipeName);
    [[[self appDelegate]addedRecipesArray] addObject:recipe];

    NSLog(@"The shopping list now contains:");
    for (Recipe *selectedRecipe in [[self appDelegate]addedRecipesArray])
    {
        NSLog(@"%@", selectedRecipe.recipeName);
    }



}
