I submitted my first free iPhone app to the App Store and users are complaining about bugs I've never seen, nor can I reproduce. How do developers allow their users to send feedback, as well as collect bug/crash reports for their iOS apps after they've been deployed to the App Store?
The best solution is to...
First, write all your logs to a rotating file log. Then create a ViewController (maybe along with the settings screen) that has a text area where users can give a description of the bug. When the click the submit button take the current log, along with any pertinent phone information, and send it to your support email address.
