I'm lost ...

I follow that course but i'm french so i don't understand everythings good but I have some skills in objective developement (C#), here is my code the same at the example I think but it don't works and I don,t know why:

quote.h
@interface Quote : NSObject{
    NSArray *_quotes;
}

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

- (NSString*) randomQuote;

@end



quote.m
#import "Quote.h"

@implementation Quote

-(NSArray *) quotes{
if(_quotes == nil){
        _quotes = [[NSArray alloc ] initWithObjects:@"1", @"1", @"1", nil ];
  }
  return _quotes;
}

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

@end

Editor tell me: Remember to allocate and initialize the instance variable '_quotes' and return it from the method named 'quotes'. bt it is not ? Thanks for help

One thing is that there's a 'v' in your quotes property which shouldn't be there

quote.h
@interface Quote : NSObject{
    NSArray *_quotes;
}

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

- (NSString*) randomQuote;

@end

you dont need that *_quotes instance variable. the property creates that for you behind the scenes. also remove the v off the end of NSArray. Other than that everything looks good.
