I want to deploy a sencha application to iPad device. I am reffering the following link.http://docs.sencha.com/touch/2-0/#!/...tive_packaging
I have created a simple hello world application and followed the deployment steps(mentioned in above link), I am able to run the package on simulator but unable to deploy it on the iPad device. As we drag the .app to iTunes or the xCode organizer, it gives me an error "The application does not have a valid signature". I had mentioned the correct certificate alias in the config file.

Here is my config file.

"applicationId":"<Provisioning Profile ID>",

"CertificateAlias":"<Certificate name>",
"orientations": ["portrait",

Please suggest a resolution.
