How to access app delegate fields within other classes?

Question

in one of my controllers I want to access fields of my app delegate. So to retrieve app delegate I use the following code:

[[UIApplication sharedApplication] delegate];

But when I try to cast it to my delegate's name I get the error that the name is undeclared.

Do I have to import the header file of the app delegate in the class where I want to access the fields?

Answer 1

you have to provide header file(MyAppDelegate.h) for app delegate.you can access appdelegate members as following.please see the link

 MyAppDelegate *appDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
