You can do a character count. For example, if you have UITextField like this:

+--------------------+
|This is a string in |
|a text view.        |
+--------------------+

you have something like 20 characters per line. If you know that number you can simply truncate your string by -substringToIndex: method.

int maxCharacters = 40; // change it to your max
if([myString length] > maxCharacters) {
    myString = [myString substringToIndex:maxCharacters];
}

You can also think about UILabel. Since you need only 2 lines of text, UILabel's numberOfLines property can solve your problem.
