Problems with random return function

Hi there on challenge task 3 of 3 I have problems with the return statement. How can I return a random quote if there is no self.Label.text to work with?

My code for task 3 of 3 looks like this:

#import "Quote.h"

@implementation Quote

- (NSArray *) quotes {
    if (_quotes == nil) {
    _quotes = [[NSArray alloc] initWithObjects: @"quote a", @"quote b", @"quote c", nil ];
  }
  return _quotes;
}

- (NSString *) randomQuote {

    int random = arc4random_uniform(self.quotes.count);
  return [self.quotes objectAtIndex:random];

}

@end

Problem solved!
