Unfortunately not in the binding text itself, at least AFAIK. There are a
number of ways to do this, the most obvious being adding a method to your model
class such as:
- (NSString *)hardReturn
{
return @"\n";
}
and adding it to your bind pattern. I have to say though, that this begs for a
dynamic property as I describe above. It is much more extensible and easier to
debug.
If, however, you find that you will need to insert carriage returns in a number
of different bindings for a number of different model objects, you might
consider using an NSFormatter that, for example, replaces occurrences of the
string "\n" with a newline. You could also set a category on NSController for
the method above, and have it available for any binding. Many options.
