Question

This time it’s not about local problem, I now have to connect to remote server and fetch information from there, and that information I want to store in my local database of an iPhone application. I don’t have any clue of even how to start this process.
Another issue is I need to retrive an Image too from given path and to store that image in my local folder.

Please help me with this.

Thank You

If fetching the information over HTTP is an option, I’d recommend you look into the excellent ASIHTTPRequest library. As for storing this information locally, take a look at Apple’s Core Data framework—support for this framework is built into Xcode.

Retrieving an image from a URL is fairly straightforward:

// Assuming imageURL is the image's URL as an NSURL.
UIImage *image = [UIImage initWithData:[NSData dataWithContentsOfURL:imageURL]];

You can then store this image in your application’s documents folder or as raw data in core data.
