Answer 1

This was the best and easy tutorials i have seen
http://dblog.com.au/iphone-development-tutorials/iphone-sdk-tutorial-reading-data-from-a-sqlite-database/

Instead of hard coding the path, try below.

databaseName = @"AnimalDatabase.sql";

// Get the path to the documents directory and append the databaseName
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
databasePath = [documentsDir stringByAppendingPathComponent:databaseName];

Your app is in a sandbox, which is not able to access anything outside of itself. Suppose your targeting jailbroken devices, this is another story.

Xcode will install your app into a sandboxed environment. You need to manually sign the app using ldid -S /YourApp.app/YourApp then copy it tom the devices /Applications directory.
