<p>NSString objects represent an immutable string of characters. NSString itself is an
|
|
|
|
|
abstract class which provides factory methods to generate objects of unspecified
|
|
|
|
|
subclasses.</p>
|
|
|
|
|
|
|
|
|
|
<p>A constant NSString can be created using the following syntax: <code>@"..."</code>,
|
|
|
|
|
where the contents of the quotes are the string, using only ASCII characters.</p>
