I am wondering if the NSUserDefaults object is shared and can be accessed from within the app delegate as well as within several of my view controllers. Basically I need to pass data from the app delegate back and forth to the view controllers. I don’t want to use a singleton. I was wondering if the NSUserDefauflts object was a way to do this.
If this is possible, how would I initialize the object so that is possible?
Thanks!
If you just use
[NSUserDefaults standardUserDefaults], the same instance will be returned every time. Different classes can then use it to store data that is persistent across sessions.If you’re just trying to pass data between parts of the app, but not store it, user defaults are not the appropriate way to do so. You should expose methods or properties on your classes that take as input the data you need to pass.
