    @autoreleasepool {

        NSArray *arr=[[NSArray alloc]initWithObjects:@12,@9,@34,@56,@11, nil];

        NSArray *newarr=[arr sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {

            return [obj1 compare:obj2];

        }];

        for (NSString *str in newarr) {

            NSLog(@"%@",str);
