Question

How organize accessing to properties MyAppDelegate object for MyClass (ex: MyViewController). Can i directory get its from MyAppDelegate or i should pass it to init method as argument or other?

Answer 1

It depends on what you want to do… Passing objects that are usefull for other classes is a good idea. But if you really want to access one of your AppDelegate property, define (for convenience) :

#define MY_APPDELEGATE ((YourAppDelegate*)[UIApplication sharedApplication].delegate)

Then access your property like this :

MY_APPDELEGATE.myproperty
