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

So can we implement this?

Any ideas ,suggestions are welcomed.....

回答1:

Maybe save the password in the NSUserDefaults and request that password if one is set...

Save the password to the keychain. Don't store it anywhere else, if you care about security. You could use SFHFKeychainUtils to do this easily.
