仿形模板Profiling Templates
在工具，您将使用仿形模板来分析你的应用程序（见图26-1）。仿形模板是一个跟踪文件已经预先配置了仪器设置进行微量的常见类型。仿形模板可用当您启动工具，创建一个新文档，或启动一个跟踪从Xcode。如果您有更高级或定制的需求，也可以创建自己的模板。In Instruments, you’ll use profiling templates to analyze your app (see Figure 26-1). A profiling template is a trace document that has been preconfigured with instruments and settings for performing a common type of trace. Profiling templates are available when you launch Instruments, create a new document, or initiate a trace from Xcode. You can also create your own templates if you have more advanced or custom needs.

Blank Profiling Template
这是一个没有任何工具的空白分析模板。如果您找不到满足您需要的模板，或者您想完全控制使用什么工具和配置设置来配置应用程序，请选择此模板。This is a blank profiling template containing no instruments. Select this template if you can’t find a template to meet your needs, or if you want full control over what individual instruments and configuration settings are used to profile your app.
NOTE
默认的仿形模板工具已经预先调整以满足在典型的情况下，大多数开发人员的需要。建议您使用它们作为起点。如有必要，您可以向任何分析模板添加附加工具并调整仪器设置。如果您确实调整了分析模板并认为有时可能需要相同的设置，则可以将修改后的文档保存为自定义模板。The default profiling templates in Instruments have been preconfigured and fine tuned to meet the needs of most developers in typical situations. It is recommended that you use them as starting points. If necessary, you can add additional instruments to any profiling template and adjust instrument settings. If you do adjust a profiling template and think you might need the same settings again sometime, you can save the modified document as a custom template.
有些工具不被任何标准分析模板所使用。要使用这些工具，必须使用空白模板创建跟踪文档，然后将所需的工具添加到其中。有关这些仪器的列表，请参见不包括在标准分析模板中的仪器。Some instruments aren’t used by any of the standard profiling templates. To use these instruments, you must create a trace document using the blank template, and then add the desired instruments to it. See Instruments Not Included in Standard Profiling Templates for a list of these instruments.

These templates can be used to profile your app in certain situations. They contain specific sets of instruments and settings designed to allow you to diagnose specific problems you may encounter while running your app from within Xcode. Note that these templates don’t appear in the Instruments list of standard templates. They are accessed via the gauges in Xcode. See Profile from Xcode gauges while debugging to learn how to profile your app using one of these templates.
