Does anyone knows how to get crash logs from customers? Instead of manually asking them to sync and go to this directory and this directory and send it.

If you are talking about normal AppStore sales, Crash Reports are available through iTunes Connect.
Just go to "Manage Your Applications" -> "Your Application" -> And click "View Details" with the version currently active in the AppStore.
You will then get the details of your application, including the crash reports that are send in by your customers.
