What is keyChain -
Key chain is the place where we can store the values which will be retain even after deleting application. Generally we store username and password in it.
Difference between KeyChain and userDefaults
The values which are store in userDeafults are deleted when we delete the app from our device but the values stored in KeyChain will not.

Nice...
ReplyDeleteI did not working for me.. :(
ReplyDeleteCould you please post your code
DeleteI've got as far as adding the KeychainItemWrapper class. When I add KeychainItemWrapper.m into my project I get al lsorts of error about incompatible pointer types.
ReplyDeleteProject is targeting iOS 6.
Yeah this code seems to be really outdated.. lots of release statements. It's annoying that apple doesn't update it. Lot's of errors, some asking me to insert (__bridge) statements, others saying incompatible pointer types..
ReplyDeleteI found this code (https://gist.github.com/dhoerl/1170641) which has no errors (for me) but I can't figure out how to make it work still... when I call something like [wrapper setObject:@"USERNAME" forKey:@"KEYUSER"];
it doesn't work...
kidding.. it works! woo hoo
DeleteThank you for your guide to with upgrade information.
