Passing Data Between Views With AppDelegate?

[JackSac67]

Hi, so I just wanted to know a method of passing data between views using AppDelegate. I've tried with individual classes and it didn't work too well, so I thought AppDelegate would work better. However, I'm always a tad scared to edit the AppDelegate because I know if I make a mistake it messes up the entire app So, any help to get me started? btw, I'm passing the data as an NSString, i.e make a string from user input in first view, then display it in a text field in the next.

It depends what you're passing and why.

It can be as simple as passing using a setter method like

Somelass *a = [[SomeClass alloc] init]
a.passVar = @"hi";

If you need to keep a constant data that all views can use, yes I would use the appDelegate. Don't be afraid of it. It's no biggie.

appDelegate *a= (appDelegate *)[[UIApplication sharedApplication] delegate];
myVar = a.sharedVar;
a.sharedVar = @"hi";
