Question

I was reading a tutorial

http://www.raywenderlich.com/1914/how-to-save-your-app-data-with-nscoding-and-nsfilemanager

about using NSCoding so that I can save my app data. Early on the tutorial modified the @interface line to look like this:

@interface ScaryBugData : NSObject <NSCoding>

My intent is to use NSCoding in my Delegate, but the @interface line already looks like this:

@interface MyAppDelegate : UIResponder <UIApplicationDelegate>
...
@end

Since I’m new to objective-c, I’m not sure how to combine the two in the same .h file.
(For that matter, I’m not clear on the syntax either.)

How would I combine and use the two statements?

Answer 1

If an class conforms to more than one protocol, you can list them commaseperated like

<UIApplicationDelegate, NSCoding>
