Question

I have a tabbar app and I want to add login window that will show just for the first time the app is launched. and want username and password to be hard coded in the app. can anyone help me with this please.

Answer 1

You probably want to use KeyChain to store the information. Keychain is a secure way to store passwords since the storage values are encrypted.

Apple also has a sample project, GenericKeychain:

This sample shows how to add, query for, remove, and update a keychain
item of generic class type. Also demonstrates the use of shared
keychain items. All classes exhibit very similar behavior so the
included examples will scale to the other classes of Keychain Item:
Internet Password, Certificate, Key, and Identity.

Another example of how to implement this using SFHFKeychainUtils is available here.
