Refactoring code challenge

Hi I'm not have any success with the second stage of the challenge I don't understand what is wrong with my code. So here's my code any help will be greatly appreciated.

#import "Quote.h"

@implementation Quote

(NSArray *) quotes { 
_quotes = [[NSArray alloc] initWithObjects:@"11",@"22",@"33", nil];

return _quotes; 
}

(NSString *) randomQuote {
return @"Some Quote";
}

@end

The error message I get after running the code says "Bummer! Remember to allocate and initialize the instance variable '_quotes' and return it from the method named 'quotes'."

This is the link for the challenge link

Thanks,

Liam

Not sure why you have hyphens "-" missing from your method names. You also need an if statement to check to see if _quotes is nil.

Edit: Have you added the quotes property to the header file?

Yes I have added the quotes property to the header file this is what I put for the first stage of the challenge:

@property (strong, nonatomic) NSArray *quotes;

Thank you Amit for your help. With your pieces of knowledge I mange to solve the second challenge

#import "Quote.h"

@implementation Quote

- (NSArray *) quotes { 
if (_quotes == nil){
_quotes = [[NSArray alloc] initWithObjects:@"11",@"22",@"33", nil];
}
return _quotes; 
}

- (NSString *) randomQuote {
return @"Some Quote";
}

@end

Thanks again, Liam
