Users have requested a "lock" on my iphone app, which makes good sense as it contains private information. I believe encryption of the data goes above and beyond what people expect on a phone, so my goal is simply to prevent unintended access to the app. My plan is to use keychain to store the password using my app name as the ServiceNa...

Is anyone aware of why this happens?...

In my code I create a "connector" which I all...
