Answer 1

Assuming that an object belonging to appDelegate.books is of class Book, try the following code snippet.

BOOL found = NO;
NSString *mystring = @"1234567";

for (Book *book in appDelegate.books) {

     NSString *checkthis = [NSString stringWithFormat:@"%@", book.LotteryNumber];

     if ([mystring isEqualToString checkthis]) {
        found = YES;
        [self showalert:checkthis];
        break;

    }
}
