If you don't want to display data to user you can use following folders and access the database from the same location which you use for storing
//To access ApplicationSupport folder of your iOS machine
NSString *appSupportDir = [NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES) lastObject];
//To access Library folder of your application (i.e. Application/appID/Library)
NSString *libraryDir = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) lastObject];
for moving data from one folder to another use following code:
NSFileManager *mngr = [[NSFileManager alloc] init];
NSString *ExpectedFilePath=[[NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"Filename.ext"];
//getting Document directory path
NSString *FilePresentAtPath=[[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"Filename.ext"];
// If the database doesn't exist in our Document folder we copy it to Library (this will be executed only one time).
if (![mngr fileExistsAtPath:ExpectedFilePath])
{
[mngr moveItemAtPath:FilePresentAtPath toPath:ExpectedFilePath error:NULL];
}
[mngr release];
