xcode - 如何在 os-signpost-point-schema 中指定符号/字符

Question

我有一个自定义的 Xcode 13.2.1 (13C100) Instrument，我最近添加了 os-signpost-point-schema .我注意到事件标有连字符/破折号而不是 ⓢ。查看我的自定义工具与标准“兴趣点”工具的比较:

我一直在挖掘 documentation虽然我打赌可以设置一些简单的属性来指示路标 ⃝ 中包含哪个符号，但它并没有向我跳出来。如何在 Instruments 中选择自定义事件点中使用的符号？

Answer 1

我posted this也在 Apple 论坛上，并收到了这个答案:

… To customize the icon that is set in the point rendering scenario, your type that is selected in your value-from field needs to have a "Special Value Treatment" defined. In your case, instead of using name, you could safely use event-concept.

The mapping between Value -> (Icon, Color) can be found in the etype documentation. For event concept, that would be: https://help.apple.com/instruments/developer/mac/current/#/dev66257045

Please let me know if that helps!

简而言之，event-concept也可以控制事件的颜色和符号。

因此，我将点 channel 中的 value-from 替换为使用解析的 event-concept 字符串，就像 color-from 正在做:

<lane>
    <title>Points</title>
    <table-ref>custom-point-table</table-ref>
    <plot-template>
        <instance-by>name</instance-by>
        <label-format>%s</label-format>
        <value-from>concept</value-from>
        <color-from>concept</color-from>
        <label-from>label</label-from>
    </plot-template>
</lane>

结果是:
