如何从核心数据读到NSData
原标题:how to read NSData from coredata

我在我的申请中建立了核心数据,我读到一个NSData物体。 我已核实,以确保所有东西都是罚款的,而且这些价值观是正确的,现在我想把这些价值观推到我的班子里。 但是,我不敢从核心数据中读到这样的东西。

我从核心数据中看到的读值就是从标准XCode生成的。 AtIndexPath:indexPath Value... as reflected below.

- (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath
{
    NSManagedObject *object = [self.fetchedResultsController objectAtIndexPath:indexPath];
    cell.textLabel.text = [[object valueForKey:@"timeStamp"] description];
}

因此,我想到的是,把所有的国家统计数据从属性中删除,因为所有我都是我自己喜欢的数据的宝库。

非常感谢任何帮助。

最新情况:

因此,由于下文所列的伟大理论,我现在如何阅读我的核心数据库的数据。

 NSManagedObjectContext *context = [self.fetchedResultsController managedObjectContext];
                    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
                    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Manz" inManagedObjectContext:context];
                    [fetchRequest setEntity:entity];
                    NSArray *fetchedObjects = [context executeFetchRequest:fetchRequest error:nil];
                    for (NSManagedObject *info in fetchedObjects) {
                        [self startTheParsingProcess:[info valueForKey:@"masters"]]; //Send to a method if you like
//                        NSLog(@"content od coredata %@", [info valueForKey:@"masters"]); // Or log it to see whats in your coredata
                    }
最佳回答

核心数据支持NSData特性。 仅增加一种模式,你将能够通过国家扫盲基金会的班子储蓄和装货。 如果你不知道这意味着什么或如何做到这一点,那么我就建议采用核心数据主,例如
