iOS Build a Simple iPhone App (iOS7) Refactoring into a Model Creating a Custom Class

Trouble with "Creating a Custom Class"

Hi,

can anyone help me out with the following ? The system kept giving me the Bummer: Remember to allocate and initialize the instance variable '_quotes' and return it from the method named 'quotes'.

This is how my Implementation-File looks like:

#import "Quote.h"

@implementation Quote

- (NSArray*) quotes {
if (_quotes == nil)
_quotes = [[NSArray alloc] initWithObjects:@"Hi", @"Hello", @"Hola", nil]];

return _quotes;
}

- (NSString*) randomQuote {

return @"Some Quote";
}

@end

Welcome to Treehouse, Samet Aslan !

You just had one square Bracket to much and one curly bracket was missing :)

- (NSArray*) quotes {
    if (_quotes == nil) {
        _quotes = [[NSArray alloc] initWithObjects:@"Hi", @"Hello", @"Hola", nil];
        };
    return _quotes;
}

This code doesn't work on my iPad or my mac. I'm typing it in exactly. What's wrong with this?
