how to publish iphone Binary (.app) file on your Hard Drive?

I am new to iphone development and want to know that how to publish the iphone binary (.app) file on your hard drive rather than App Store.

Because I have 开发者_高级运维heard that one have to publish it on App Store and than from there he can install it into iphone device.

Because the application on which I am working is not supposed to be public as its for our company's employees so no need to publish on App Store if its not much necessary or forced.

Your company should create a enterprise developer account and get all the needed certificates for their server. This way you can deploy the app from your companies server without using the App Store.
