苹果Live Activities功能使用指南：动态岛与CarPlay场景下的信息追踪设置

自iPhone 14 Pro起，苹果以药丸形挖孔设计取代了此前的刘海屏方案，并由此引入“动态岛”功能，将这一设计限制转化为iOS体验中的实用交互区域。Live Activities（实时活动）正是动态岛的核心应用之一，可在不打开相关应用的情况下，实时显示计时器、导航指引、音乐播放状态及体育比分等信息，外卖配送和航班追踪等众多第三方应用也已适配该功能。

Live Activities通常默认开启。若某些应用未显示实时活动，用户可前往“设置”>“应用”，选择对应应用，确认“实时活动”开关已打开。虽然实时活动与常规通知相互独立，但若仍未收到预期更新，建议同时为该应用开启通知权限。设备锁屏时，实时活动也会显示在锁屏界面。用户可在“设置”>“面容ID与密码”中验证密码后，下滑至“锁定时允许访问”区域，确保“实时活动”选项已开启。

在CarPlay场景下，iPhone上的实时活动会自动显示在CarPlay仪表板中，即应用列表左侧的分屏视图内。若正在使用全屏应用，实时活动将以通知形式出现在屏幕底部。若觉得干扰过多，可在CarPlay中关闭该功能，或针对特定应用单独禁用实时活动。若未显示，可打开CarPlay中的“设置”应用，下滑确认“实时活动”开关已启用，同时确认“CarPlay中的建议”（或“仪表板中的建议”）选项已开启。如仍未出现，可尝试关闭“驾驶专注模式”。此外，用户还可向CarPlay添加小组件，以便在不打开应用的情况下快速访问控制和信息，小组件位于CarPlay仪表板最左侧区域。

如何在iPhone和CarPlay上启用实时活动
无需每隔两分钟打开应用，即可随时掌握重要动态。
在大多数安卓手机早已改用小尺寸挖孔屏来放置前置摄像头的时代，iPhone 14 Pro却以一个长条形药丸状开孔亮相。此后，苹果一直将其作为标准设计，只有入门级“e”系列手机和iPhone Duo例外，甚至在iPhone 18 Pro系列上还将这个开孔进一步缩小了。
这是因为iPhone在开孔内不仅装有摄像头，还集成了Face ID所需的额外传感器。苹果没有用巧妙设计的壁纸来遮掩这个药丸形开孔，而是顺势而为推出了灵动岛，利用开孔周围的区域，将原本尴尬的设计限制转化为iOS体验中实用的一部分。
使用手机时，iPhone的实时活动会显示在灵动岛上。它们展示你可能想随时关注的信息，无需频繁切回关联应用：计时器、导航方向、音乐播放和体育比分都可以作为实时活动显示。许多第三方应用，如外卖配送和航班追踪服务，也已适配使用灵动岛。
实时活动默认应该是开启的，但如果你在某些应用上看不到它们，请检查是否不小心被关闭了。在iPhone上，前往“设置”>“应用”，选择任何出现问题的应用。确保“实时活动”开关已启用。虽然实时活动独立于普通通知运行，但如果你没有看到预期的更新，也可以为该应用开启通知。
当你不使用设备时，这些活动也会出现在锁屏上。如需确认此功能已启用，请前往“设置”>“面容ID与密码”。确认密码后，向下滚动到“锁定时允许访问”部分，确保“实时活动”已开启。
在CarPlay上使用实时活动
CarPlay让你在驾驶时轻松获取iPhone上的重要信息，而不会过于分心。作为其中的一部分功能，它可以显示实时活动，让你追踪外卖配送状态或即将到来的航班动态。
iPhone上的实时活动会自动显示在CarPlay仪表板上，即应用列表左侧的分屏视图。如果你正在使用一个全屏应用，实时活动仍会以通知形式显示在屏幕底部。如果它们让你过于分心，你可以随时在CarPlay中关闭该功能，或如上所述针对特定频繁推送的应用禁用实时活动。
如果你没有看到它们，请在CarPlay中打开“设置”应用，向下滚动并确保“实时活动”开关已启用。你还应确认“CarPlay中的建议”（或“仪表板中的建议”）选项已打开。如果它们仍未出现，请尝试关闭正在运行的“驾驶专注模式”。
除此之外，你还可以向CarPlay添加小组件，以便快速控制和查看应用信息，无需打开应用。小组件位于CarPlay仪表板的最左侧区域。在“设置”应用中多花点时间，你会发现更多自定义CarPlay在车载显示屏上显示方式的方法。

How to enable Live Activities on iPhone and CarPlay
Keep track of important updates without having to open the app every two minutes.
At a time when most Android phones had already switched to tiny hole-punch cutouts to house their front-facing cameras, the iPhone 14 Pro launched with a long pill-shaped cutout. Apple has used this as its standard since then, aside from the budget "e" phones and iPhone Duo, and even made it smaller for the iPhone 18 Pro series.
This is because iPhones pack more than just a camera inside the cutout; there are additional sensors required for Face ID to work. Instead of hiding the pill with cleverly designed wallpapers, Apple leaned into it with the Dynamic Island, using the surrounding area to turn an otherwise awkward design constraint into a useful part of the iOS experience.
Your iPhone's Live Activities show up on the Dynamic Island when using your phone. They display information you might want to keep an eye on without having to constantly switch back to the associated app: timers, navigation directions, music playback and sports scores can be displayed as Live Activities. Many third-party apps like food delivery and flight tracking services have also adapted to use the Dynamic Island.
Live Activities should be enabled by default, but if you don't see them for certain apps, check if they've accidentally been turned off. On your iPhone, navigate to Settings > Apps and select any app that's been giving you trouble. Make sure the Live Activities slider is enabled. Though Live Activities work independently of regular notifications, you might want to also enable notifications for the app if you're not seeing the expected updates.
These activities will also appear on the Lock screen when you're not using your device. To make sure this is enabled, visit Settings > Face ID & Passcode. Confirm your passcode, then scroll down to the Allow Access When Locked section and be sure Live Activities is on.
Using Live Activities on CarPlay
CarPlay makes it easy to access vital info from your iPhone without getting too distracted while driving. As part of this, it can display Live Activities so you can track the status of a food delivery or updates for an upcoming flight.
Live Activities from your iPhone are automatically displayed on the CarPlay Dashboard, the split-screen view to the left of your app list. If you're using an app that covers the entire screen, Live Activities will still be shown as notifications at the bottom of the display. If they become too distracting, you can always turn the feature off in CarPlay or disable Live Activities for specific noisy apps, as above.
In case you're not seeing them, open the Settings app in CarPlay, scroll down and make sure the Live Activities toggle is enabled. You should also confirm the Suggestions in CarPlay (or Suggestions in Dashboard) option is turned on. If they still don't appear, try turning off Driving Focus if it's running.
Besides this, you can add widgets to CarPlay for quick controls and information from apps without having to open them. Widgets live in the leftmost section of the CarPlay Dashboard. Spend a little more time in the Settings app, and you'll discover more ways to customize how CarPlay looks on your car's display.
