在iPhone应用程序重新启动之间未保存sqlite数据

Question

When the app is running, I can create tables, insert and retrieve data from and to my sqlite database, but as soon as I relaunch the app, the database is empty again. Shouldn't the data be stored, until I specifically say "DROP..."

Answer 1

I don't have enough reputation to comment but you don't have a lot of information here. My best guess is that you aren't saving your context which is handled by an instance method of NSManagedObjectContext.

- (BOOL)save:(NSError **)error;
