# Passing Data between View Controllers (with MessageBox-Concept)
MessageBox is a simple concept for decoupling entities.
For example entity A can place a message that entity B can read whenever suitable.
A view controller would like to talk to another view controller, but you don't want to create a strong or weak relationship.
# Simple Example Usage
let messageBox:MessageBox = MessageBox() // set messageBox.setObject("TestObject1", forKey:"TestKey1") // get // but don't remove it, keep it stored, so that it can still be retrieved later let someObject:String = messageBox.getObject(forKey:"TestKey1", removeIfFound:false) // get // and remove it let someObject:String = messageBox.getObject(forKey:"TestKey1", removeIfFound:true)
