iOS KeyChain not retrieving values from background

by

My question was close to the mark for the reason why, but not quite. After reading through blog after blog, tutorial after tutorial, I finally found one that gave off a hint of what might be happening.

Locked home screens. The keychain tutorials always left the accessibility settings for the keychain blank, so it would default to Apple’s lowest/safest access level. This level however doesn’t allow keychain access if the user has a passcode on the lock screen. Bingo! This explains the sporadic behavior and why this only happens to a small percentage of users.

One line of code, solves the entire mess.

[wrapper setObject:(__bridge id)kSecAttrAccessibleAlways forKey:(__bridge id)kSecAttrAccessible];

Add this line where I’m setting the username and password values. Works like a charm. Hope this will help someone out there. It confounded me for quite a while until I was able to put the pieces together.
