This is sample code demonstrating API, technology or techniques in development.
|
|
|
|
|
Although this sample code has been reviewed for technical accuracy, it is not
|
|
|
|
|
final. Apple is supplying this information to help you plan for the adoption of
|
|
|
|
|
the technologies and programming interfaces described herein. This information
|
|
|
|
|
is subject to change, and software implemented based on this sample code should
|
|
|
|
|
be tested with final operating system software and final documentation. Newer
|
|
|
|
|
versions of this sample code may be provided with future seeds of the API or
|
|
|
|
|
technology. For information about updates to this and other developer
|
|
