Acces instances in different classes

[DrJones]

Hi, i know this is a very common question, but i can't figure it out, so please give me some hints.

I have a viewcontroller that calculates a value in this case a price lets say 100. The value is displayed in a alertview as a string. In the alert view there is a button called save. When you press that a modal viewcontroller pops up, and lets the user insert some info such as name and price. The string value should already be present. When the user clicks save again, it saves the data to a tableview.

So its pretty simple to-do, but i can't figure out how to acces the strings and add data to the array from the 3 classes. Can anyone give me a hint?

Create a data container singleton.

Take a look at the password generator app that I list in my signature. That app illustrates using a data container singleton.

The idea is that you create a single object that is shared across your entire app. You write a class method that you can use to get a pointer to the singleton.

As you come up with values that need to be shared between the different objects in your app, add them as properties of your singleton.
