What does this have to do with an array?
Anyway, why not append the to strings together first, then set that in the textview.
Code:
NSString *text = [NSString stringWithFormat:@"Winner: %@\nDescription: %@", [race winner], [race description]];
[self.raceView.raceDescription setText:text];
Is that what you are trying to do? Your question is a bit confusing.
