problem with code challenge 2 of 3; Build a Simple iPhone App(iOS7) - Refactoring into a Model

Hello Joe,

First off in you .h where you declare _quotes don't call it that. call it just quotes because the underscore is used when calling it, it basically replace self. so it should look like this

@property (strong, nonatomic, readonly) NSArray *quotes;

try that, Kai

Well, you are correct. However, after reviewing the video I note that in the design pattern I was also supposed to add an instance variable _quotes to the @interface in the .h file in addition to the property for quotes like this:

@interface Quote : NSObject { NSArray *_quotes; }

However that doesn't satisfy the "compiler" either and I still get the "Bummer! Remember to allocate and initialize the instance variable '_quotes' and return it from the method named 'quotes'." message.

yes it is. Went back and reviewed the video a couple more times. (This specific design pattern is shown at 7:20 in the video.) I've also sent a group of screen shots to the support people but don't expect an answer until early in the week from them.

Hey Joe,

I wrote it and here is the answer,

1) .h

@property(strong, nonatomic)NSArray *quotes;

2) .m

-(NSArray*)quotes{
  if(_quotes == nil){
    _quotes = [[NSArray alloc]initWithObjects:@"hello", @"team", @"treehouse", nil];
  }

  return _quotes;
}

3) .m

- (NSString *) randomQuote {
    int random = arc4random_uniform(self.quotes.count);
    return [self.quotes objectAtIndex:random];
}

there we go ket me know if this works for you.

Happy hacking, Kai
