Passing Data from App delegate to View Controller

Question

I need to Pass an string from App delegate to my Initial View Controller , Can somebody listed me the best way to do it , also i tried to Save and Retrieve using NS user De

Answer 1

Here it is for Swift:

View Controller

let appDelegate = UIApplication.sharedApplication().delegate as AppDelegate

Furthermore, if you have an object that you want to pass between view controllers (for example, I had CloudKit data I wanted to share) add this to the App Delegate:

    /* Function for any view controller to grab the instantiated CloudDataObject */
func getCloudData() ->CloudData{
    return cloudDataObject
}

Then back in the View Controller

var model : CloudData = self.appDelegate.getCloudData()
