removeitematpath to remove Olddb.sqlite - iphone

Question

I got this app that needs to be updated with a new database.
I want to remove the old one and replace it with the new.
This is the code I'm using:
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {
if (persistentStoreCoordinator != nil) {
return persistentStoreCoordinator;
}
NSString *storePath = [[self applicationDocumentsDirectory] stringByAppendingPathComponent: #"Newdb.sqlite"];
NSFileManager *fileManager = [NSFileManager defaultManager];
// If the expected store doesn't exist, copy the default store.
if (![fileManager fileExistsAtPath:storePath]) {
NSString *defaultStorePath = [[NSBundle mainBundle] pathForResource:#"Newdb" 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];
persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]];
NSError *error;
if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) {
NSLog(#"Unresolved error %#, %#", error, [error userInfo]);
exit(-1); // Fail
}
return persistentStoreCoordinator;
}
I want my app to check at start-up if the Olddb.sqlite is there and if yes delete it!

here's the solution...
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir = [documentPaths objectAtIndex:0];
NSString *pathInDocuments = [docsDir stringByAppendingPathComponent:#"Olddb.sqlite"];
if (pathInDocuments) {
[fileManager removeItemAtPath:pathInDocuments error:NULL];
}
