NSCredential in UIAlertView to connect to a WebService

Question

I have a NavigationController that hold ViewControllers, but I want that to access to some ViewControllers an authentification via an UIAlertView. (Some ViewControllers content need a authentification).

That UIAlertView will send data to a Webservice to check first if the login and password are correct and then receive back the datas + a token to store in the Iphone (like that you need to authenticate only once).

I'm going to check on each ViewControllers before access it, if the user already authenticate, by checking if the token is registered in the Iphone.

But I don't really know how can I figure out everything, I mean especially the architecture to make all the things working : UIAlertView, NSCredential, storing light data in the Iphone, etc...

Can anyone clear my mind ?

Answer 2

Lookup UIAlertView delegate methods. You will be checking the button index that was pressed from those methods to fire a method of your choice. Don't forget to add the delegate.

UIViewController <UIAlertViewDelegate>
