Has anyone used Buzz Andersen's Simple iPhone Keychain code?

问题

You can find it here.

I'm trying to understand his sample code in order to write a simple program with that stores passwords into the keychain and retrieves them for login. Has anyone done this before? It would be most appreciated if I can see any examples you may have.

回答1:

There's really no code to demonstrate, he lists both calls there.

Heres's an example, for what it is worth:

NSError *error;

[SFHFKeychainUtils storeUsername:@"fred" andPassword:@"mypassword123" forServiceName:@"myService" updateExisting:YES error:&error];

NSString *storedPassword = [SFHFKeychainUtils getPasswordForUsername:@"fred" andServiceName:@"myService" error:&error];

To other newbies that use this code as is and don't understand why it doesn't work. Notice that the ServiceName is different (First without capital - "myService" and second with capital: "MyService"), that's why it doesn't work. Make the ServiceName the same.
