Question

I have read this post: what happens to NSLog info when running on a device?

…but wondering if NSLog is a problem when distributing the app such as filling up the memory or something? I am only interested to see it when i test the consistency of my input data to the database.

The reason is that I have NSLog to control when i load the data into my database in the simulator. I could remove it when i upload but it would be good if i do not need to?

You should remove it. For example if you log contents of a UITableViewCell (in -tableView:cellForRowAtIndexPath:), it can make a big difference in performance, especially on slower hardware.

Use a macro to keep NSLog output in Debug mode, but remove it from Release mode. An example can be found on the following site: http://iphoneincubator.com/blog/debugging/the-evolution-of-a-replacement-for-nslog
