I have just started using core data. I want to setup a pre-populated db. I read somewhere that core data creates a sqlite file when a core data app is run. I don't know where to look for it though.
I followed the instructions over on this blog but did not find the sqlite file over the location specified directory /Users/<Username>/Library/Application Support/iPhone Simulator/User/Application/<Application GUID>/Documents/<database name.sqlite>
nor in the application directory.
here is my code for persistentCoordinator.
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator
{
if (__persistentStoreCoordinator != nil)
{
return __persistentStoreCoordinator;
}
NSString *storePath = [[[self applicationDocumentsDirectory] path] stringByAppendingPathComponent:@"coredata.sqlite"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:storePath]) {
NSString *defaultStorePath = [[NSBundle mainBundle] pathForResource:@"coredata" ofType:@"sqlite"];
if (defaultStorePath) {
[fileManager copyItemAtPath:defaultStorePath toPath:storePath error:NULL];
}
}
NSURL *storeURL = [NSURL fileURLWithPath:storePath];
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
NSError *error = nil;
__persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];
if (![__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error])
{
NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
abort();
}
return __persistentStoreCoordinator;
}
Those files are in ~/Library/Application Support/iPhone Simulator/[SDK version]/Applications/[App GUID]/Documents
for me, both for Xcode 3 and Xcode 4.
If you have multiple SDKs, make sure to look in all the different SDK version directories for your app.
For me it was in whatMuregSaid/[Application Guid]/Library/Application Support/[AppName]/filename.sqlite
