How do you prevent Xcode 7 Playgrounds from automatically running?
提问by BK15
I'm working on an Xcode 7 Playground that has many things running at once. Whenever I make an edit, it refreshes, restarts what was running and runs through the entire code again. That crashes my playground around every 15 minutes. Is there a way to prevent playgrounds from automatically running whenever I make an edit?
我正在开发一个同时运行很多东西的 Xcode 7 Playground。每当我进行编辑时，它都会刷新、重新启动正在运行的内容并再次运行整个代码。每 15 分钟就会让我的操场崩溃一次。有没有办法在我进行编辑时防止 Playgrounds 自动运行？

In the lower-left part of the Playground there's a right-facing blue arrow, looking like a "play" button.
在 Playground 的左下方有一个向右的蓝色箭头，看起来像一个“播放”按钮。
Do a long click on this button and you will get two options: "Automatically Run" and "Manually Run".
长按此按钮，您将获得两个选项：“自动运行”和“手动运行”。
Choose the latter to put the Playground is manual mode and start/stop its execution yourself by clicking on this button.
选择后者将 Playground 置于手动模式并通过单击此按钮自行启动/停止其执行。
You can also trigger the code execution by making a custom shortcut to the "Execute Playground" Editor menu command.
您还可以通过创建“执行操场”编辑器菜单命令的自定义快捷方式来触发代码执行。
Go to Xcode > Preferences...then go to Key Bindings, scroll down to Editor Menu for Playgroundand add a new shortcut of your choice by double-clicking in the right column in front of the Execute Playgroundcommand.
转到Xcode > Preferences...然后转到Key Bindings，向下滚动到Editor Menu for Playground并通过双击Execute Playground命令前面的右列添加您选择的新快捷方式。

Actually, you CAN map a shortcut for "Execute Playground" to Cmd+R.
实际上，您可以将“执行操场”的快捷方式映射到Cmd+ R。
Use macOS keyboard shortcuts, instead of Xcode's keybindings.
使用 macOS 键盘快捷键，而不是 Xcode 的键绑定。
Go to System Preferences> Keyboard> Shortcuts,
转到System Preferences> Keyboard> Shortcuts,
and in App shortcuts, click on +.
并在 中App shortcuts，单击+。
Choose Xcode.app, and add a new shortcut for "Execute Playground" (you have to type precisely this!).
选择Xcode.app，并为“执行操场”添加一个新的快捷方式（您必须准确地输入这个！）。
Then click on Add.
然后点击Add。
Now you can use this shortcut in Xcode.
现在您可以在 Xcode 中使用此快捷方式。
And don't worry for conflicts (at least up to Xcode 9): Execute Playgroundis not available for standard Xcode projects, and Runis not active for Playgrounds.
并且不要担心冲突（至少到 Xcode 9）：Execute Playground不适用于标准 Xcode 项目，并且Run不适用于 Playgrounds。
