Logging iphone feature usage

Are there any frameworks/services for logging user usage of an iphone application?

Say you want to log events like 'creating a contact' or something similiar, to know how people are ac开发者_开发知识库tually using your app.

I have used and really like Pinch Media. (Recently renamed to flurry)

http://www.flurry.com

It gives you a bunch of analytics without you having to do anything special. You can also add hooks to your code to see how often a particular section of code is run and get analytics on that area as well.

Yes, Flurry Analytics does this. You can even pass parameters to your events so you can break down which options are most popular, etc.

What you could do is simply log these messages perhaps as a Log custom class, and whenever you need to add anything to the log, you would simply add a new Log item to the AppDelegate or wherever you need to store the list of Logs. Then you can save them to the file system.

For achieving the logging the feature usage in flurry the url below can be helpful. http://wiki.flurry.com/index.php?title=Analytics_-_Best_Practices
