之前，我讨论了如何擦除和重新安装您的 macOS 操作系统(how to wipe and reinstall your macOS operating system)，由于逐渐积累的垃圾，建议您这样做。但你的 iPhone 也不例外。它仍然是一台电脑，尽管它很小，可以放在你的口袋里。它像任何其他计算机一样收集数字碎片。
这就是为什么您应该始终养成每六个月左右擦拭和重新格式化您的 iOS 设备的习惯。iPad 也是一样，但由于我的 iPad 运行着令人尴尬的旧版 iOS，我的 iPad 已经走到了尽头，我今天将专注于我的 iPhone 7。
预擦拭清单(Pre-Wiping
Checklist)
在您全力以赴并擦拭整个手机之前，您需要先做一些事情。
首先是对整个手机进行iCloud 备份。(iCloud backup)这可以通过点击设置，然后点击屏幕顶部的Apple ID名称来完成。(Apple ID)
然后向下滚动并点击 iCloud。
然后向下滚动到“iCloud Backup”并点击它。
现在点击“立即备份(Back Up)”按钮，让它做它的事情。
接下来要做的是记下您的所有应用程序。iCloud（如果您已备份所有内容）将为您重新安装所有应用程序，但我始终相信拥有保险单。所以我把所有屏幕都截图了，所以我有一些东西可以参考以防万一。只需几秒钟即可完成。
下一步是确保 iCloud 已正确备份您的所有照片。这可以通过检查另一台 iOS 或Mac
设备来完成，或者使用Dropbox的“相机上传”功能将所有图像移动到Dropbox文件夹中。再一次(Again)，你永远不能太小心，特别是如果你的手机上有数百甚至数千张照片。
接下来，如果您的手机上有任何 iTunes 音乐，请确保您在其他地方的 iTunes 上备份了它（比如在您的Mac或Windows PC 上）。
最后，如果您使用 Google Authenticator或Authy（您应该使用），那么您需要关闭所有帐户的双因素身份验证。因为当手机被擦除时，您的 2FA 代码也将如此，您将重新进入这些在线帐户。
请记住(Remember)列出已停用的帐户，以便以后重新激活它们。
如果您在 iCloud 帐户上使用双因素身份验证（之后您没有其他 iOS 或Mac来访问这些代码），您需要在线访问 iCloud 并在那里关闭 2FA。
开始 iPhone 擦除过程(Beginning the
iPhone Wiping Process)
现在一切都已备份，所有重要信息都已记录下来，是时候进行一些擦除了。这实际上是一个相当快速且无痛的过程，但我总是对有多少人拥有手机多年而从未这样做过一次感到震惊。当我这样做时，我总是注意到一个轻快的性能爆发。
转到设置->常规。一直向下滚动(Scroll)到底部以“重置”。
现在您将看到各种重置选项，具体取决于您想要走多远。核选项是“擦除所有内容(Erase All Content)
和设置”。
然后它会询问您是否要先进行 iCloud 备份。但是，由于我们刚刚做了一个，您可以忽略它并选择“立即擦除(Erase)”。
系统会要求您输入屏幕PIN码，然后要求您确认 - 两次 - 如果您真的想擦除 iPhone。
然后是超级骗子，它会要求您输入您的 Apple ID 密码以确认。
现在屏幕将变为白色并带有黑色Apple标志，并将开始自行擦除和重新安装。
完成后，要记住的事情......(After It’s Done,
Things To Remember…..)
正如我之前所说，如果您正确地将所有内容备份到 iCloud，那么当您之后再次登录时，它将重新安装您的应用程序。但是，请确保您的所有应用程序都已计算在内。
另外，请记住：
- 重新登录到您的 wifi 网络。
- 设置(Set)Touch ID、FaceID和/或屏幕密码。
- 从您的 iCloud 备份中恢复所有内容。
- 打开“查找我的 iPhone”。
- 打开“iCloud 备份”。
- 在Google Authenticator(Google Authenticator)或Authy 中将(Authy)双因素身份验证切换回您的帐户。
- 检查以确保您的照片回来了。
- 从 iTunes 传回您的音乐。
- (Set)使用您的卡片详细信息设置Apple Wallet 。
- 浏览设置(Settings)并按照您喜欢的方式进行自定义。您已将手机重置为出厂设置，因此键盘、自定义词典、快捷方式等内容将不复存在。
享受您的（希望如此）活泼的新 iPhone。
How To Wipe & Reformat Your iOS Device
Previously, I discussed how to wipe and reinstall your macOS operating system, which is recommended due to a gradual accumulation of gunk. But your iPhone is no different. It is still a computer, albeit a tiny one which fits in your pocket. It collects digital debris like any other computer.
This is why you should always make a habit every six months or so of wiping and reformatting your iOS device. The iPad is the same, but since my iPad is literally on its last legs running an embarrassingly old version of iOS, I am going to focus on my iPhone 7 today.
Pre-Wiping
Checklist
Before you go all nuts and wipe your entire phone, there are
some things you need to do first.
The first is to do an iCloud backup of your entire phone. This can be done by tapping on Settings and then your Apple ID name at the top of the screen.
Then scroll down and tap on iCloud.
Then scroll down to “iCloud Backup” and tap that.
Now tap the “Back Up Now” button and let it do its thing.
The next thing to do is make a note of all your apps. iCloud (if you have backed everything up) will reinstall all of your apps for you, but I always believe in having an insurance policy. So I make screenshots of all screens, so I have something to refer to just in case. It takes only seconds to do.
The next step is to make sure that iCloud has backed up all
of your photos properly. This can be done by checking on another iOS or Mac
device, or use something like Dropbox’s “Camera Uploads” function to move all
of your images to your Dropbox folder. Again, you can never be too careful,
especially if you have hundreds or even thousands of pictures on your phone.
Next, if you have any iTunes music on your phone, make sure
you have a backup of it on iTunes elsewhere (say on your Mac or Windows PC).
Finally, if you use Google Authenticator or Authy (and you
SHOULD be), then you need to switch off two-factor authentication on all of the
accounts. Because when the phone is wiped, so will your 2FA codes be and so
will your way in back into those online accounts.
Remember to make a list of the deactivated accounts so you
can reactivate them later.
If you use two-factor authentication on your iCloud account (and you don’t have another iOS or Mac to access those codes afterward), you need to go to iCloud online and switch 2FA off there too.
Beginning the
iPhone Wiping Process
Now that everything has been backed up and all essential
information has been noted down, it’s time to do some wiping. This is actually
a rather quick and painless process but I am always shocked at how many people
have their phones for years and never do this once. I always notice a brisk
performance burst when I do this.
Go to Settings–>General. Scroll all the way down to the
bottom to “Reset”.
Now you are going to see a variety of reset options,
depending on how far you want to go. The nuclear option is “Erase All Content
and Settings”.
It will then ask you if you want to do an iCloud backup
first. However, since we have just done one, you can ignore this and select
“Erase Now”.
You will be asked for your screen PIN code and then asked to
confirm – twice – if you really want to erase the iPhone.
Then to be super-duper sure, it will ask you for your Apple
ID password to confirm.
Now the screen will go white with the black Apple logo and
will begin to wipe and reinstall itself.
After It’s Done,
Things To Remember…..
As I said before, if you backed everything up to iCloud properly, then it will reinstall your apps when you sign back in again afterward. But nevertheless, make sure all of your apps are accounted for.
Also, remember to :
- Log back into your wifi network.
- Set up Touch ID, FaceID, and / or a screen passcode.
- Restore everything from your iCloud backup.
- Turn on “Find My iPhone”.
- Turn on “iCloud Backup”.
- Switch two-factor authentication back on your accounts in Google Authenticator or Authy.
- Check to make sure your photos are back.
- Transfer your music back from iTunes.
- Set up Apple Wallet with your card details.
- Go through Settings and put things back to the way you liked them, customization-wise. You have reset your phone back to factory settings so things like keyboards, custom dictionaries, shortcuts, and so on, will be gone.
Enjoy your (hopefully) zippy new iPhone.
