Call a function in AppDelegate?

Question

Following the solution (the highest-voted answer actually) at UITextField Example in Cocos2d, I managed to do it except the line

[[[UIApplication sharedAppli         


        

Answer 1

Right now, your class doesn't know anything about your delegate's methods. You need to import your delegate into your implementation, not your interface (to avoid cycled imports).

For example,

#import "AppDelegate.h"

Then you should cast the returned delegate in your nested method call to be your delegate type. For example:

[(AppDelegate *)[[UIApplication sharedApplication] delegate] specifyStartLevel];
