系统可能看起来像一个复杂的应用程序。它可以用来收集关于你的应用程序的各种有用信息，并帮助你诊断和解决问题。但是，整个仪器工作流程相对简单（见图2-1）。Instruments may seem like a complex app. It is, in that it can be used to gather all kinds of useful information about your app, and help you diagnose and resolve problems. However, the overall instrument workflow is relatively simple (see Figure 2-1).
Figure 2-1The Instruments workflow
在高层次上，它由以下主要阶段组成：At a high level, it consists of the following main phases:
设置包含所需工具和设置的跟踪文档。Set up a trace document containing the desired instruments and settings.
目标设备和应用程序配置文件。Target a device and an app to profile.
应用程序简介。Profile the app.
分析分析过程中捕获的数据。Analyze the data captured during profiling.
修正源代码中的任何问题。Fix any problems in your source code.
在Xcode中测试你的应用程序的调试，咨询导航计（图2-2）跳水之前，仪器。这些量规提供了应用程序的CPU、内存、能源使用量等高级信息。通常，它们提供了您所需的所有信息，以提高性能并快速解决常见问题。在需要进行更详细的分析时使用工具。While testing your app with Xcode, consult the debug navigator gauges (Figure 2-2) before diving into Instruments. These gauges provide high-level information about your app’s CPU, memory, energy usage, and more. Often, they provide all the information you need to improve performance and resolve common problems quickly. Use Instruments when you need to perform more detailed analysis.
