I'm developing Salesforce iOS application.
From the application frequently the user has to modify data which is available on Salesforce.com.
When a user taps on edit I'm launching salesforce login screen and prompting to enter username and password all the time.
So I have decided to implement SSO using Salesforce Oauth. I have done everything I'm able to receive an
access_token once user is authenticated with Salesforce.com.
My question is - lets say "If the user want to edit a lead with id as 0097hjy7", URL to edit this lead will be "https://sales.mysalesforce.com/0097hjy7" when this URL launch on browser it prompt to enter username and password again.
How can I navigate the user to "https://sales.mysalesforce.com/0097hjy7" this URL without asking username and password all the time by using the access_token available with me?
