Hex in a stringWithFormat BAD ACCESS

Question

Here is a part of my code:

I have a string which is formed by a stringWithFormat like this:

NSString * DestChoice = [NSString stringWithFormat:@\"%@\", D         


        

Answer 1

NSString * DestChoice = [NSString stringWithFormat:stringWithFormat:@"%@%@", Dest1String];

You are indicating that you want to format two objects with %@%@, but you are only supplying a single object (Dest1String).
