iPhone 上的 Back Tap 是什么？
您可以在运行 iOS 14 及更高版本的 iPhone 上使用回击。只需轻按手机背面(tapping the back of your phone)，即可自动执行操作。
您可以选择使用双击或三击。这使您可以灵活地将一个、另一个或两者用于不同的事物。只需(Simply)快速轻按 iPhone 背面两到三下即可调用您在下面设置的操作。
注意：根据您使用的 iPhone 手机壳类型，您可能需要用力点按才能触发该功能。
如何启用后点击
要在 iPhone 上打开后点击，请打开“设置”(Settings)应用。
- 选择辅助功能(Select Accessibility)并选择触摸(Touch)。
- 向下滚动(Scroll)并选择Back Tap。
- 选择双击(Select Double Tap)或三击(Triple Tap)以设置您的第一个后击操作。
- 从“系统(System)”、“辅助功能(Accessibility)”、“滚动手势(Scroll Gestures)”或“快捷方式(Shortcuts)”中选择要分配给双击或三次轻击的操作。
- 点击左上角的箭头以保存点击动作并返回。
然后，您可以设置另一个后点击或使用每个后续屏幕左上角的箭头退出辅助功能(Accessibility)设置并返回主设置(Settings)屏幕。
如果您想稍后禁用回击，请返回“设置”(Settings)中的同一位置，然后选择“无”进行回击操作。
使用 Back Tap 进行系统操作
决定使用哪个系统操作进行回击的最佳方法是考虑您在设备上执行最多的操作。
您是否发现自己经常打开相机拍照？你经常使用 Siri(use Siri)来获取信息吗？您是否每天多次捕获屏幕截图？(capture screenshots)您(Are)是否经常调高音乐音量？
这些操作中的每一个都被视为后点击菜单中的系统操作(System Action)。如上所述访问双击(Double Tap)或三击设置，然后选择(Triple Tap)相机(Camera)、Siri、屏幕截图(Screenshot)或音量调高以进行后击操作。
请务必检查其他系统操作，例如打开控制中心(Control Center)、访问主屏幕、打开手电筒和调用锁定(Lock)屏幕。
然后，试试你的新水龙头。请记住(Remember)，双击时，请快速点击手机背面两次，而三次点击时，请点击三下。
使用 Back Tap(Use Back Tap)进行辅助功能操作(Accessibility Actions)
也许您使用iPhone 的辅助功能(iPhone’s Accessibility features)比系统操作更多。您可以从后点击菜单中的十多个辅助功能操作中进行选择。
(Select AssistiveTouch)如果您打开这个方便的功能来控制您的屏幕，请选择 AssistiveTouch 。为您想大声朗读(to hear spoken out loud)的所有项目选择“朗读屏幕(Choose Speak Screen)” 。选择缩放(Pick Zoom)以在更大的范围内轻松查看屏幕上的项目。
这些中的每一个都是后点击菜单中的辅助功能操作(Accessibility Actions)。转到如上所述的双击(Double Tap)或三击设置，然后选择这些操作之一或其他操作，例如(Triple Tap)放大镜(Magnifier)、语音控制或旁白。
同样，最好对您新设置的回击进行测试，以确保它适合您。
使用 Back Tap 滚动
虽然这似乎是一个简单的选项，但您可以使用返回点击向上或向下滚动。如果您使用返回点击，则无需换手、使用拇指或拖动滚动条。
向下(Scroll Down)滚动和向上(Scroll Up)滚动是后点击菜单中的滚动手势(Scroll Gestures)。如果您在研究或查看时经常在网页或文档上滚动，请考虑双击向上滚动和三次向下滚动。
使用 Back Tap 作为快捷方式
在 iPhone 上使用回击的另一种方便方法是使用快捷方式。如果您利用Shortcuts 应用程序(the Shortcuts app)并设置操作来播放播放列表、分享您的位置或启动计时器，然后将这些方便的操作添加到后点击中。
您创建的每个快捷方式都显示在返回点击菜单的快捷方式列表中。(Shortcuts)只需(Simply)为双击或三次点击选择快捷方式，即可享受对快捷方式的超快速访问。
让我们看看如何设置快捷方式并通过后点击访问它。您可以打开快捷方式(Shortcuts)应用程序并根据需要进行操作。

Useful Things You Didn’t Know You Could Do With Back Tap on iPhone
Introduced with iOS 14, back tap gives you a quick and easy way to perform actions on your iPhone. From turning on the flashlight to taking a screenshot to using customized shortcuts, you might be underusing this handy feature.
We’ll walk through some system actions, helpful accessibility tools, scroll gestures, and nifty shortcuts for doing something useful with the Apple back tap feature on iPhone.
What Is Back Tap on iPhone?
You can use back tap on iPhones running iOS 14 and later. By simply tapping the back of your phone, you can automatically perform actions.
You have options to use a double-tap or triple-tap. This gives you flexibility to use one, the other, or both for different things. Simply tap the back of your iPhone two or three times quickly to invoke the action you set up below.
Note: Depending on the type of iPhone case you use, you may need to tap firmly to trigger the feature.
How to Enable Back Tap
To turn on back tap on your iPhone, open the Settings app.
- Select Accessibility and pick Touch.
- Scroll down to and choose Back Tap.
- Select Double Tap or Triple Tap to set up your first back tap action.
- Choose the action you want to assign to the double or triple tap from System, Accessibility, Scroll Gestures, or Shortcuts.
- Tap the arrow on the top left to save the tap action and go back.
You can then set up the other back tap or use the arrows on the top left of each subsequent screen to exit the Accessibility settings and return to the main Settings screen.
If you want to disable back tap later, return to the same spot in the Settings and select None for the back tap action.
Use Back Tap for System Actions
The best way to decide which system action to use for back tap is to think about those you perform the most on your device.
Do you find yourself opening the Camera to snap photos frequently? Do you often use Siri to get information? Do you capture screenshots many times per day? Are you constantly turning your volume up for your music?
Each of these actions is considered a System Action in the back tap menu. Visit the Double Tap or Triple Tap setup as described above and then choose Camera, Siri, Screenshot, or Volume Up for the back tap action.
Be sure to check out other system actions too like opening Control Center, accessing your Home screen, turning on the flashlight, and invoking the Lock screen.
Then, give your new tap a try. Remember, for a double-tap, tap the back of your phone two times quickly and for a triple-tap, tap it three times.
Use Back Tap for Accessibility Actions
Maybe you use your iPhone’s Accessibility features more than system actions. You can pick from over ten accessibility actions in the back tap menu.
Select AssistiveTouch if you open this handy feature to control your screen. Choose Speak Screen for all of those items you want to hear spoken out loud. Pick Zoom to easily view items on your screen on a larger scale.
Each of these are Accessibility Actions in the back tap menu. Go to the Double Tap or Triple Tap setup as described above and then choose one of these actions or another like Magnifier, Voice Control, or VoiceOver.
Again, it’s a good idea to give your newly set up back tap a test to make sure it works for you.
Use Back Tap for Scrolling
While this may seem like a simple option, you can use back tap to scroll up or down. You don’t have to switch hands, use your thumb, or drag the scroll bar if you use back tap instead.
Scroll Down and Scroll Up are Scroll Gestures in the back tap menu. If scrolling on web pages or documents is something you do frequently while researching or reviewing, consider a double tap to scroll up and triple tap to scroll down.
Use Back Tap for Shortcuts
One more handy way to use back tap on iPhone is for shortcuts. If you take advantage of the Shortcuts app and set up actions to play a playlist, share your location, or start a timer, then add those convenient actions to a back tap.
Each shortcut you create displays in the Shortcuts list in the back tap menu. Simply choose the shortcut for your double or triple tap and enjoy super-fast access to the shortcut.
Let’s look at how to set up the shortcut and access it with a back tap. You can open the Shortcuts app and follow along if you like.
- Select the Gallery tab and use the Search Gallery box to find the shortcut you want.
- Here are eight handy shortcuts that make back tap a useful tool. If you tap the links on your iPhone, they should open directly in the Shortcuts app.
- Play Playlist: Play a preselected playlist from the Music app.
- Log Water: Log your water intake in the Health app by choosing the number of ounces.
- Break Timer: Start a timer for a work break with the activity and duration.
- Home ETA: Share how long it will take you to get home from work, the store, or a road trip.
- Calculate Tip: Figure out how much your tip should be using 12, 15, 18, or 20 percent of the bill.
- Time Tracking: Keep track of time you spend on a project or activity.
- Shazam and Save: Use Shazam to identify the current song playing and save it to a preselected spot.
- Running Late: Let others know you’re running late for a meeting or event and when you plan to arrive.
If there’s a particular shortcut you want but can’t find it in the Gallery, you can create a custom shortcut instead.
- Once you select the shortcut, choose Set Up Shortcut and follow the prompts. Using our examples above, you’ll do things like pick the playlist, create a list of options, or add the activities and durations.
- Pick Add Shortcut to save it.
- Head to the Settings to set up the back tap for the shortcut you created. Choose Accessibility > Touch > Back Tap. Then pick either the Double Tap or Triple Tap option.
- Scroll to the Shortcuts section and choose the action you want.
- Use the arrows on the top left to exit and then give your back tap shortcut a try.
