Question

I have been using Grinich’s method of using the userinfo category for passing on objects, in which case I’m passing an array of FeedItem class objects. However, modelItems as well as feedItems return a null even when myPassedObject is able to print my items when i NSLog it.

 id myPassedObject = [query objectForKey:@"__userInfo__"];

    NSArray *modelItems = myPassedObject;

    for (FeedItem *feedItem in modelItems) {

     [feedItems addObject:feedItem];   
    }

Answer 1

Try casting myPassedObject to an NSArray when you assign it to modelItems. Doesn’t seem to be anything else wrong.
