Question

如何访问cloudKit用户中的每个属性。我有一个用于获取的记录ID数组。我在一本字典中找回记录（本例中为2）。

    NSMutableArray *recordIDs;
    for (NSString *recordName in recordNames) {
        CKRecordID *recordID = [[CKRecordID alloc] initWithRecordName:recordName];
        [recordIDs addObject:recordID];
    }
    CKFetchRecordsOperation *fetchOperation = [[CKFetchRecordsOperation alloc] initWithRecordIDs:recordIDs];
    fetchOperation.fetchRecordsCompletionBlock = ^(NSDictionary /* CKRecordID * -> CKRecord */ *recordsByRecordID, NSError *operationError) {

        NSLog(@"recordsByRecordID %@", recordsByRecordID);
};

控制台记录以下内容：

2015-04-11 11:04:15.829 projectName[10154:555807] recordsByRecordID {
    "<CKRecordID: 0x7fea3bd86f80; _c835c6d554eafe23xxxxb65a1a9dd94d:(_defaultZone:__defaultOwner__)>" = "<CKRecord: 0x7fea44596fc0; recordType=Users, recordID=_c835c6d554eafe23xxxxb65a1a9dd94d:(_defaultZone:__defaultOwner__), recordChangeTag=i7rxe5ce, values={\n    identifier = \"3E7837F6-C23C-44B2-89E8-5D9DF9AB061E\";\n    points = 50;\n    username = \"_c835c6d554eafe23xxxxb65a1a9dd94d\";\n}>";
    "<CKRecordID: 0x7fea3e0614d0; _cd5f8486186028eaxxx6b6597489619:(_defaultZone:__defaultOwner__)>" = "<CKRecord: 0x7fea3e2567a0; recordType=Users, recordID=_cd5f8486186028eaxxx6b6597489619:(_defaultZone:__defaultOwner__), recordChangeTag=i7s7706j, values={\n    identifier = \"4B3B374E-42B0-47B7-8638-A8967C23FA21\";\n    points = 250;\n    username = \"_cd5f8486186028eaxxx6b6597489619\";\n}>";
}

我想检索用户名和点并将其添加到本地词典。

Answer 1

我明白了。看起来我需要为每条记录传递recordID然后传入要检索的密钥。

for (CKRecordID *recordID in recordsByRecordID) {
    NSString *pointsString  = recordsByRecordID[recordID][PointsKey];
    NSLog(@"string %@", pointsString);
}

如何使用cloudkIt fetchOperation.fetchRecordsCompletionBlock
