如何在Google跟踪代码管理器iOS中更改clientId（＆amp; cid）？

Question

我需要更改Google跟踪代码管理器中的＆amp; cid（客户端ID）参数。我尝试在kGAIClientId（Google Analytics）的跟踪器上设置GAI。

self.tracker =[[GAI sharedInstance] trackerWithTrackingId:GAProperty_VALUE];
[self.tracker set:kGAIClientId value:NEW_VALUE];

不起作用！

我也尝试使用新值在数据层中推送&cid，但不起作用。

以下是我在日志中获得的内容：

GoogleTagManager verbose: GoogleAnalytics 3.14 -[GAIBatchingDispatcher persist:] (GAIBatchingDispatcher.m:517): Saved hit: {
    parameters =     {
        "&_crc" = 0;
        "&_s" = 86;
        "&_u" = ".7nL";
        "&_v" = "mi3.1.4";
        "&a" = 240807461;
        "&aid" = "***";             // removed
        "&an" = "***";              // removed
        "&av" = "2.6.5";
        "&cd" = "***";              // removed
        "&cd1" = "***";
        "&cd10" = unknown;
        "&cd11" = no;
        "&cd15" = "/home/";
        "&cd41" = iOS;
        "&cid" = "7c5824a7-5851-4829-a6c9-0a09a11fbe98";
        "&dm" = "x86_64";
        "&ds" = app;
        "&sr" = 750x1334;
        "&t" = appview;
        "&tid" = "***";             // removed
        "&ul" = "en-us";
        "&v" = 1;
        "&z" = "***";
        gaiVersion = "3.14";
    };
    timestamp = "2016-02-17 09:27:12 +0000";
}

如果有人知道如何更改它，请帮忙！

谢谢。
