Last week I mentioned a straightforward tutorial for working with the iOS user data API’s including a user’s contacts.
Here’s an iOS Objective-C example from Daniel Bader providing more insight into working with a user’s contact list. The example shows not only how to gather a user’s contacts but also how to guess a user’s favorite contacts.
This is done by rating each individual contact using the assumption that the more information a user has about a contact the greater the importance of that contact.
You can find the example code along with more details on the techniques used on Daniel’s blog here.
No private APIs are used so this is safe within your apps, and from my testing looks like it does a good job of guessing which contacts are most important.
