I have an iOS app with a login view.
I need to have the login-data the whole time until the user ends the app or click “logout”.
How and where to store it?
Are something equel like “member variables” possible in iOS / objective C?
If you’re going to be storing username/password data, it’s probably best to store it in the keychain. If you’re only looking to keep track of whether a user is logged in, then consider storing a flag of some kind in
NSUserDefaults. You can clear data when the application exits through theapplicationWillTerminate:method of your application delegate.
