To limit the string to 5 characters, use substringWithRange:

NSString *newTitle = [origTitle substringWithRange:NSMakeRange(0, min(5, origTitle.length))];

The call min(5, origTitle.length) picks the smaller of 5 and the length of the title that you want to set. You need to include <math.h> to use min function.
