@interface NSArray (Map) {
}
    //[fruitBasket mapWithBlock: ^(id x){ return [x peeledFruit]; }];
- (NSArray *)mapWithBlock:  (id (^)(id obj))block;
@end
@implementation NSArray (Map)

- (NSArray *)mapWithBlock:  (id (^)(id obj))block{
    NSMutableArray *array = [[NSMutableArray alloc] init ];
    for (id item in self) {
        [array addObject:block(item)];
    }
    return array;
}

@end
