## Getting Around Instruments ##

Instruments has several key windows and dialogs.

### Profiling Template Selection Dialog ###

当仪器的推出，你提出一个清单的分析包含预配置的仪器设置模板文件选择。此列表包含一组标准模板以及您可能创建的任何自定义模板。（参见图5-1。）When Instruments launches, you’re presented with a list of profiling templates—files containing sets of preconfigured instruments—from which to choose. This list includes a set of standard templates as well as any custom templates you may have created. (See Figure 5-1.)

**Figure 5-1仿形模板选择**The profiling template selection dialog![image: ../Art/instruments\_profilingtemplate\_dialog\_2x.png][image_ .._Art_instruments_profilingtemplate_dialog_2x.png]

剖析模板选择对话框由以下主要元素组成：The profiling template selection dialog consists of the following primary elements:

*  **目标设备列表：单击此选项选择您希望配置的设备。Target device list:** Click this to select the device on which you wish to profile.
 *  **目标进程列表：单击此以选择要配置的流程或流程。Target process list:** Click this to select the process or processes to profile.
 *  **“筛选”按钮：单击这些按钮过滤模板列表，以显示标准模板、自定义模板或最近使用的模板。Filter buttons:** Click these to filter down the list of templates to display just the standard templates, custom templates, or recently used templates.
 *  **搜索字段：输入一些文本以快速找到您需要的模板。这将搜索模板标题和描述。Search field:** Enter some text to quickly find the template you need. This searches template titles and descriptions.
 *  **模板列表：分析模板的列表，如果单击了筛选按钮或输入了搜索条件，则模板可能会被过滤。Template list:** The list of profiling templates, which may be filtered if you clicked a filter button or entered search criteria.
 *  **模板描述：对当前选定的分析模板的简短描述，它有助于确定所选模板是否满足您的需要。Template description:** A short description of the currently selected profiling template, which can be helpful for determining whether the selected template meets your needs.
 *  **选择按钮：单击此按钮，根据当前选定的模板创建一个新的配置文件。Choose button:** Click this to create a new profile document, based on the currently selected template.
    
    当按下选项键时，此按钮会更改为配置文件。单击概要文件按钮根据当前选中的模板创建一个新文档，并立即开始对目标进程进行分析。This button changes to Profile when you press the Option key. Click the Profile button to create a new document based on the currently selected template and immediately begin profiling the target process.

*  **打开按钮：单击此打开先前保存的配置文件，而不是从一个新模板开始。Open button:** Click this to open a previously saved profile document, rather than starting with a fresh template.
 *  **取消按钮：单击此按钮关闭模板选择对话框。Cancel button:** Click this to close the template selection dialog.

TIP

你可以显示仿形模板选择对话框，在任何时间，选择文件>新建（或按了N命令）。You can display the profiling template selection dialog at any time by choosing File > New (or pressing Command-N).

### Trace Document ###

跟踪文件（图5-2）是用于组织和配置工具的分析，进行数据采集，并查看分析结果。你创建一个新的跟踪文件，启动仪器选择仿形模板或启动分析从Xcode，码头，或命令行。您还可以保存和重新打开跟踪文档，在这些文档中您已经配置了工具和收集的数据。跟踪文档可以包含许多非常详细的信息，并且这些信息通过许多窗格和区域呈现给您。A trace document (Figure 5-2) is used to organize and configure instruments for profiling, initiate data collection, and view and analyze the results. You create a new trace document by launching Instruments and choosing a profiling template or by initiating profiling from Xcode, the Dock, or the command line. You can also save and reopen trace documents in which you’ve configured instruments and collected data. A trace document can contain a lot of extremely detailed information, and this information is presented to you through a number of panes and areas.
