Keychain Services API

The GenericKeyChain sample does not run inside the iPhone simulator.  I found out that WordPress for iPhone is using the SFHFKeychainUtils class which can be download from GitHub.   The author has a blog about it.  I wrote a simple iPhone program to test the function and it works great!

WordPress for iPhone – Source

The WordPress for iPhone source can be downloaded from subversion.  This page has the instructions.

I downloaded the latest trunk version.  The app is using the Keychain Services API to store account information so that next time, when the app starts, it would automatically login to the blog.  Apple has a sample program called GenericKeychain that uses the Keychain Services API.

I have not looked at the WordPress for iPhone source in detail.  But one thing I noticed was that NSLog is used a lot for debugging purposes.  To prevent those statements from being printed in the release version, I think it is better to do something like this.

iPhone Core Data

I am working on an iPhone app that needs data storage.  I could use SQLite, but since Core Data is available in iPhone OS 3.0, I decide to learn it.  Here are some good resources.
