静态分析器一直告诉我,我的请求对象的保留计数为 +1,仪器告诉我那里有泄漏。但是,无论我尝试在哪里发布它,它都会让我的应用程序崩溃。NSPredicate 对象也是如此。请帮忙,我正在努力赶上最后期限。
// Fetch Requests
// Method that returns an array of NSManagedObjects in the managedObjectContext with a predicate of who ordered
- (NSArray *)fetchDataWithEntity:(NSString *)entity andSortKey:(NSString *)key andPerson:(Person *)whoOrdered

NSEntityDescription *entityDescription = [NSEntityDescription entityForName:entity
