I got a few crash reports from users that have a problem with my CoreData app.
Given the following code:
/*
Returns the persistent store coordinator for the application.
If the coordinator doesn't already exist, it is created and the application's
store added to it.
*/
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator
{
if (_persistentStoreCoordinator == nil) {
NSURL *storeUrl = [NSURL fileURLWithPath:self.persistentStorePath];
_persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]
initWithManagedObjectModel:[NSManagedObjectModel mergedModelFromBundles:nil]];
NSError *error = nil;
NSPersistentStore *persistentStore = [_persistentStoreCoordinator
addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl
options:nil error:&error];
NSAssert3(persistentStore != nil, @"%s at %d: Unhandled error adding
persistent store: %@", __FUNCTION__, __LINE__, [error localizedDescription]);
NSLog(@"Created persistent store '%@' at URL %@",
persistentStore, storeUrl);
}
return _persistentStoreCoordinator;
}
When the MOC tries to perform a save, an exception is generated:
Exception reason
This NSPersistentStoreCoordinator has no persistent stores. It cannot perform a
save operation.
