Launch Instruments

该仪器应用在Xcode应用程序，所以推出是在Xcode的最直接的方式。你也可以启动它间接地通过码头，启动，或命令行。The Instruments app lives inside the Xcode app, so the most direct way to launch it is from within Xcode. You can also launch it indirectly via the Dock, Launchpad, or the command line.

从Xcode启动仪器Launch Instruments from Xcode

启动仪器的最直接的方式是通过在Xcode Xcode菜单。The most direct way to launch Instruments is via the Xcode menu in Xcode.

1. Open Xcode.

2. Choose Xcode > Open Developer Tool > Instruments.

   

你也可以启动仪器以剖面的程序你都积极致力于在Xcode。You can also initiate Instruments in order to profile an app you are actively working on in Xcode.

1. 启动Xcode打开你的项目。Launch Xcode and open your project.

2. Do one of the following:

   • Choose Product > Profile.

     

   • Click and hold the Run button in the Xcode toolbar and choose Profile.

     

   • Press Command-I.

如果你需要用相同的模板定期您的应用程序配置文件，你可以设置你的Xcode项目自动用它当你启动分析。If you need to profile your app with the same template regularly, you can set up your Xcode project to automatically use it whenever you initiate profiling.

1. 启动Xcode打开你的项目。Launch Xcode and open your project.

2. Choose Product > Scheme > Edit Scheme.

   

   或者，在Xcode工具栏的格式弹出菜单，选择“编辑方案。Or, from the Scheme pop-up menu in the Xcode toolbar, choose Edit Scheme.

4. 在“信息”下，单击“工具弹出”菜单并选择所需的分析模板。Under Info, click the Instrument pop-up menu and choose the desired profiling template.

   

   如果你chooseask发射，仪器显示其仿形模板选择对话框，在启动时。If you chooseAsk on Launch, Instruments displays its profiling template selection dialog when it starts up.

5. Click Close.

6. 启动分析。请打开Xcode项目简介。Initiate profiling. See To profile an opened Xcode project.

从码头发射仪器Launch Instruments from the Dock

仪器可在码头的Xcode图标启动。Instruments can be launched from the Xcode icon in the Dock.

1. Open Xcode.

2. Control-click the Xcode icon in the Dock, and then choose Options > Open Developer Tool > Instruments from the shortcut menu.

   

You can also add Instruments to your Dock for quick access. The quickest way to do this is to launch Instruments and then set it to stay in the Dock.

1. Open Xcode.

2. Choose Xcode > Open Developer Tool > Instruments.

   

   Instruments launches and its icon appears in your Dock.

   

3. Control-click the Instruments icon in the Dock, and then choose Options > Keep in Dock from the shortcut menu.

   

Launch Instruments from Launchpad

启动自动显示驻留在您的应用程序文件夹的应用程序。由于仪器不在应用程序文件夹（至少不是直接在Xcode，它是在应用程序文件夹），它没有出现在Launchpad。但是，您可以通过为工具创建一个别名并将其放入应用程序文件夹中来添加它。Launchpad automatically displays apps that reside in your Applications folder. Because Instruments isn’t in the Applications folder (at least, not directly—it’s in Xcode, which is in the Applications folder), it doesn’t appear in Launchpad. However, you can add it by creating an alias to Instruments and putting it in your Applications folder.

1. Open Xcode.

2. Choose Xcode > Open Developer Tool > Instruments.

   

   Instruments launches and its icon appears in your Dock.

   

3. Control-click the Instruments icon in the Dock, and then choose Options > Show in Finder from the shortcut menu.

   

4. Option-Command-drag the Instruments app icon in the Finder to your Applications folder.

   An alias of Instruments is created and added to your Applications folder.

5. Remove the alias suffix from the filename of the Instruments alias.

   Instruments now appears in Launchpad.

   

Launch Instruments from the Command Line

You can use the open command to launch any app in OS X via Terminal.

1. Launch Terminal (in /Applications/Utilities/).

2. Run the following command:

   open /Applications/Xcode.app/Contents/Applications/Instruments.app
