How to set a password for an application in iOS

Question

I am developing an application in iOS where I want to provide a password. If the user can enter a password and set it, and later, when he opens the application, he must first ask for a password to enter,

So can this be implemented?

Any ideas, suggestions are welcome .....

Answer 1

Perhaps save the password in NSUserDefaults and request a password if one is set ...

Save the password in the keychain. Do not store it anywhere else if you care about security. You can use SFHFKeychainUtils to make this easy.
