I have a scenario, where I have to show 20-30++ images loaded from server, and need to store for offline, and application updates also.

Do using this kind of file writing would be helpful, rather than going with Coredata for storing images. Does this kind of storage would be helpful in handling the didReceiveMemoryWarnings..

Oh Thanks, Yes I stuck that code in the AppDelegate and after I made a conection from my UIButton to the First Responder, The console showed me this:
2011-03-06 14:58:12.934 WriteToFile[7772:207] Documents directory: (
“file1.txt”
)
Now I have some reading to do, I need to understand what just happened there. This is WAY different from VB. I’m not finding many concepts that are common. Thanks for your suggestion. Mick

If you’ve verified the code is being called inside the action method, I’m not sure where the problem could be. You could try moving the code into a place such as the app delegate to see if it works as expected.

Hello. Been learning Objective c for 2 weeks now. I ran this code inside an IBAction and the console only shows nothing, only that the app has started. What might I be missing.
Thanks

The Apple preferred (yet, abbreviated in this snippet–no check of empty array) way of getting the Documents directory is as follows:

[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex: 0];
