Question

我正在加载我的最新电子邮件，而且我保存了最新的UID，因为稍后如果用户重新加载电子邮件列表我想要从该UID获取所有电子邮件到现在......为此，我正在使用

UInt64 start = lUid;
UInt64 end = UINT64_MAX;

MCOIMAPMessagesRequestKind requestKind = MCOIMAPMessagesRequestKindHeaders;
MCOIndexSet *uids = [MCOIndexSet indexSetWithRange:MCORangeMake(start, end)];

MCOIMAPFetchMessagesOperation *fetchOperation = [imapSession fetchMessagesOperationWithFolder:@"INBOX"
                                                                                  requestKind:requestKind
                                                                                         uids:uids];

此操作始终返回结果，但我收到了最新的电子邮件...所以我试图制作

UInt64 start = lUid + 1;

但它完全一样。

修改

我正在查看记录器，最后一个UID是34038所以当我拨打电话时，启动参数是34039 ...所以为什么我收到ID为34038的电子邮件？

2015-01-20 18:33:06.852 App[25022:730644] mailcore - IMAP: 8 UID FETCH 34039:* (UID ENVELOPE BODY.PEEK[HEADER.FIELDS (References)])

任何人都知道发生了什么事？

编辑2： 所以这是我的代码

UInt64 start = lUid + 1;
UInt64 end = UINT64_MAX;

MCOIMAPMessagesRequestKind requestKind = MCOIMAPMessagesRequestKindHeaders;
MCOIndexSet *uids = [MCOIndexSet indexSetWithRange:MCORangeMake(start, end)];

MCOIMAPFetchMessagesOperation *fetchOperation = [imapSession fetchMessagesOperationWithFolder:@"INBOX"
                                                                                  requestKind:requestKind
                                                                                         uids:uids];

void(^fetchHandler)(NSError *, NSArray *, MCOIndexSet *) = ^(NSError *error, NSArray *fetchedMessages, MCOIndexSet *vanishedMessages) {

    if( error ) {
        completionHandler(UIBackgroundFetchResultFailed);

        NSLog(@"Error downloading message headers:%@", error);
    }

    NSMutableArray *currentMessages = [NSMutableArray arrayWithArray:fetchedMessages];

    if( [currentMessages count] > 0 ) {

        MCOIMAPMessage *lastMessage = [fetchedMessages lastObject];
        NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];
        [defaults setObject:@(lastMessage.uid) forKey:@"lastUID"];
        [defaults synchronize];

        completionHandler(UIBackgroundFetchResultNewData);

    }
    else {
        completionHandler(UIBackgroundFetchResultNoData);
    }

};

[fetchOperation start:fetchHandler];

这是执行该调用时的记录器
