Detailed Description

This class renders the camera preview to the screen and searches for an SDK license key in a QR code.

Method Documentation

+ (void) initializeControl

This message initializes the control and must be sent to the class before it is used.

This message initializes the control for use and must be sent to the class before it is used. It is ok to send the message more than once. A common way to do this is in your UIViewController subclasses initialize or init methods.

- (void) readLicense

Reads an SDK license from the camera preview.

This call returns immediately and starts asynchronously searching for an SDK license. The search will continue indefinitely until an SDK license is found.

Once an SDK license is positively read, the delegate will receive a licenseCaptureControl:errorCode:daysRemaining:license: message.

If license string is valid it will be set into SDK for licensing.
