During the activation key request, you should have entered some essential information:

1. Company name
2. Reference email address
3. Bundle identifier

First two fields are self-explaining.

The third field is the unique bundle identifier you've chosen for your application: it is defined in the .plist file or in the application target (“General” tab)

To activate your license you should invoke the correct activate method (Global_activeXXX) in PDFVGlobal.m, APP_Init() method, based on your license type, like this:

BOOL succeeded = Global_activePremium("com.radaee.pdf.PDFViewer", "Radaee", "radaee_com@yahoo.cn", “89WG9I-HCL62K-H3CRUZ-WAJQ9H-FADG6Z-XEBCAO");

Then you can call APP_Init() on application launch:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

APP_Init();
