iPhone 是一款非常稳定的移动设备，但许多原因可能会导致它崩溃。错误(Buggy)的 iOS 版本、过时的第三方应用程序和损坏的系统设置只是其中的一小部分。
当您的 iPhone 崩溃时，您可能会在系统软件尝试自行恢复时看到带有旋转圆圈的黑屏。但是，这有时会失败，您将继续无限期地看到同一个屏幕。
当 iPhone 卡在带有加载圈的黑屏上时，强制重启应该可以修复它。如果这没有帮助，您必须使用恢复模式(Recovery Mode)或DFU 模式(DFU Mode)来解决问题。
强制重启 iPhone
强制重启（或硬重置）需要关闭 iPhone 内部电路并重新接通电源。无论系统软件的状态如何，这都会提示设备自动重启。您可以通过按下或按住一系列或一组按钮来触发强制重启，这些按钮会根据 iPhone 型号而变化。
在大多数情况下，强制重启 iPhone 是摆脱加载圈问题的黑屏的可靠方法。它还可以解决其他问题，例如iPhone 卡在 Apple 标志(iPhone stuck at the Apple logo)上或iPhone 显示白屏(iPhone displaying a white screen)。
执行强制重启后，您的 iPhone 应该（希望）毫无问题地加载 iOS。然后，您可以输入您的设备密码以访问主(Home)屏幕。
iPhone 8 系列、iPhone X 及更新机型(iPhone 8 Series, iPhone X, and Newer)
在配备Face ID(Face ID)或Touch ID的 iPhone 8 系列、iPhone X 和更新的 iPhone 机型上，您必须按正确的顺序按下以下按钮。
1. 快速按下音量调高(Volume Up)按钮并松开。
2. 快速按下降低音量(Volume Down)按钮并松开。
3. 立即按住侧边(Side )按钮。然后，当您在屏幕上看到Apple标志时立即释放它。(Apple)
仅限 iPhone 7 和 iPhone 7 Plus(iPhone 7 and iPhone 7 Plus Only)
如果您使用 iPhone 7 或 iPhone 7 Plus，请同时按住降低音量(Volume Down)和侧边(Side )按钮，当您在屏幕上看到Apple标志时松开它们。(Apple)
iPhone 6s、iPhone 6s Plus 及更早机型(iPhone 6s, iPhone 6s Plus, and Older)
在 iPhone 6s、iPhone 6s Plus 和旧款 iPhone 机型上，按住主(Home )屏幕和侧边(Side)/顶部(Top)按钮，直到您在屏幕上看到Apple标志。(Apple)
使用恢复模式
如果您的 iPhone 强制重启但继续显示带有加载圆圈的黑屏，则您可能正在处理损坏的系统软件。要解决此问题，您必须在恢复模式下(Recovery Mode)重新安装或重置 iOS 。
我们已经在另一篇文章中介绍了有关在 iPhone 上进入和使用恢复模式(entering and using Recovery Mode on the iPhone)所需了解的所有信息，但这里有一个简短的概述：
1. 首先通过USB将 iPhone 连接到Mac或 PC。
2.在 Mac 或 PC 上打开Finder或iTunes 。
2. 为您的 iPhone 型号执行强制重启按钮，但即使在看到Apple(Apple)标志后也要按住按钮或按钮。不久之后，您应该会在 iPhone 和Mac/PC上看到恢复模式屏幕。(Recovery Mode)
进入恢复模式(Mode)后，您有两个选择 - 更新 iOS 或将其恢复为出厂设置。
更新 iOS(Update iOS)
当您选择恢复模式(Recovery Mode)时，iPhone 会重新安装最新版本的 iOS，而不会丢失您的数据。你必须先试一试。
选择更新(Update )以提示您的Mac或 PC 从Apple服务器下载 iPhone 系统软件的最新副本。然后，按照屏幕上的说明重新安装 iOS。
恢复 iPhone(Restore iPhone)
在恢复模式下(Recovery Mode)恢复 iPhone会将设备重置为出厂设置。您将丢失数据，但您可以在重置过程后 通过 iCloud 或Finder/iTunes
如果更新 iOS 无法修复加载圈问题的黑屏，您必须仅恢复您的 iPhone。选择恢复 iPhone(Restore iPhone) >恢复和更新( Restore and Update)以重置设备。
使用 DFU 模式
DFU（设备固件更新(Device Firmware Update)）模式(Mode)会在从头开始重新安装之前擦除系统软件和 iPhone 的固件（使硬件工作的编程）。只有在恢复模式(Recovery Mode)无法解决加载圈问题的黑屏时，您才必须使用它。
进入DFU 模式需要您在将 iPhone 连接到(DFU Mode)Mac或 PC时执行一组复杂的按钮操作。我们建议查看这篇关于在 iPhone 上进入和使用 DFU 模式的(entering and using DFU Mode on iPhone)帖子以了解详细信息。
进入DFU 模式(DFU Mode)后，您只有一个选择——将 iPhone 恢复为出厂默认设置。选择恢复 iPhone，(Restore iPhone,)您的Mac或 PC 将自动下载并安装最新版本的 iOS，包括设备固件。
同样，您会丢失您的数据，但如果您的 iPhone 开始正常工作，您可以稍后通过 iCloud 或 iTunes/Finder 备份取回这些数据。
避免出现旋转圆圈问题(Spinning Circle Issue)的黑屏(Avoid Black Screen)提示
如果强制重启您的 iPhone 或在恢复模式下(Recovery Mode)更新它有帮助，那么下面的提示应该可以最大限度地减少再次发生相同问题的机会。
保持 iOS 更新(Keep iOS Updated)
新的(New)iOS 更新附带了许多稳定性修复和增强功能。如果您最近没有更新您的 iPhone，请前往“设置”(Settings) > “通用(General )” > “软件更新”(Software Update)并安装所有待处理的更新。

如果使用第三方应用程序导致 iPhone 崩溃并卡住，请尝试应用最新的应用程序更新。为此，请长按App Store图标，选择Updates，然后选择Update All。
释放内部存储空间(Free Up Internal Storage)
如果存储空间快用完，iPhone 也可能会卡在带有加载圆圈的黑屏上。
前往“设置”(Settings ) > “通用(General )” > “ iPhone 存储(iPhone Storage)”并使用各种存储建议（删除视频、iMessage 附件等）来释放空间。您还可以删除或卸载不必要的应用程序(delete or offload unnecessary apps)并减少 iPhone 的其他存储空间(reduce your iPhone’s Other storage)。
降级到稳定频道(Downgrade to Stable Channel)
如果您使用 iOS 的 beta 版本，您肯定会经常遇到系统软件崩溃。降级到稳定频道，帮自己一个忙。这是降级 iOS 应采取的措施(what you should do to downgrade iOS)。
重置所有设置(Reset All Settings)
重置 iPhone 上的设置可帮助您处理黑屏背后的任何损坏配置以及旋转圆圈问题。转到设置(Settings )>常规(General )>重置(Reset )，然后选择重置所有设置(Reset All Settings)以执行设置重置。
出厂重置 iPhone(Factory Reset iPhone)
如果您的 iPhone 在崩溃后仍然卡住，您必须将设备重置为出厂设置。之后，您可以使用备份恢复数据。
首先creating an iCloud or a Finder/iTunes backup。然后，转到“设置”(Settings ) > “通用(General )” > “重置(Reset )”并选择“抹掉所有内容和设置”(Erase All Content and Settings)以将 iPhone 恢复出厂设置。
iPhone 满载
Recovery/DFU Mode强制重启或恢复您的 iPhone应该可以解决黑屏和加载圈问题。确保(Make)仔细阅读上面的指示，以防止它成为一个反复出现的问题。

iPhone Stuck on Black Screen with Loading Circle? 4+ Ways to Fix
The iРhone is an incredibly stable mobile device, but many reasons can cause it to crash out on yoυ. Buggy iOS releases, outdated third-party apps, and corrupt system settings are just a few of them.
When your iPhone crashes, you might see a black screen with a spinning circle as the system software attempts to recover itself. That can sometimes fail, however, and you’ll continue to see the same screen indefinitely.
A force-restart should fix an iPhone when it gets stuck on a black screen with a loading circle. If that doesn’t help, you must use Recovery Mode or DFU Mode to sort things out.
Force Restart iPhone
A force restart—or a hard reset—requires shutting down and turning back the power to the iPhone’s internal circuitry. That prompts the device to reboot automatically regardless of the state of the system software. You can trigger a force-restart by pressing or holding down a sequence or set of buttons that change depending on the iPhone model.
In most cases, force restarting an iPhone is a sure-fire way to get rid of the black screen with a loading circle issue. It can also fix other problems, such as an iPhone stuck at the Apple logo or an iPhone displaying a white screen.
After performing a force-restart, your iPhone should—hopefully—load iOS without issues. You can then enter your device passcode to access the Home screen.
iPhone 8 Series, iPhone X, and Newer
You must press the following buttons in the correct order on the iPhone 8 series, iPhone X, and later iPhone models that feature Face ID or Touch ID.
1. Quickly press the Volume Up button and release it.
2. Quickly press the Volume Down button and release it.
3. Immediately press and hold the Side button. Then, release it as soon as you see the Apple logo on the screen.
iPhone 7 and iPhone 7 Plus Only
If you use an iPhone 7 or iPhone 7 Plus, hold down the Volume Down and Side buttons at the same time and release them when you see the Apple logo on the screen.
iPhone 6s, iPhone 6s Plus, and Older
On the iPhone 6s, iPhone 6s Plus, and older iPhone models, press and hold both the Home and the Side/Top buttons until you see the Apple logo on the screen.
Use Recovery Mode
If your iPhone force-restarts but continues to display the black screen with a loading circle, you’re likely dealing with corrupt system software. To fix that, you must reinstall or reset iOS in Recovery Mode.
We’ve covered everything you need to know about entering and using Recovery Mode on the iPhone in a separate post, but here’s a brief rundown:
1. Start by connecting your iPhone via USB to a Mac or PC.
2. Open Finder or iTunes on the Mac or PC.
2. Perform the force-restart button presses for your iPhone model, but keep holding the button or buttons even after seeing the Apple logo. You should see the Recovery Mode screen on both your iPhone and Mac/PC soon after.
Once you enter Recovery Mode, you have two options—update iOS or restore it to factory settings.
Update iOS
When you opt for Recovery Mode, the iPhone reinstalls the latest version of iOS without losing your data. You must give that a shot first.
Select Update to prompt your Mac or PC to download the latest copy of the iPhone’s system software from the Apple servers. Then, follow the on-screen instructions to reinstall iOS.
Restore iPhone
Restoring an iPhone in Recovery Mode resets the device to factory settings. You will lose your data, but you can get that back via an iCloud or Finder/iTunes backup after the reset procedure.
You must only restore your iPhone if updating iOS fails to fix the black screen with the loading circle issue. Select Restore iPhone > Restore and Update to reset the device.
Use DFU Mode
DFU (Device Firmware Update) Mode wipes both the system software and the iPhone’s firmware (the programming that makes the hardware work) before reinstalling them from scratch. You must only use it if Recovery Mode fails to resolve the black screen with the loading circle issue.
Entering DFU Mode requires you to perform a complicated set of button presses while having your iPhone connected to a Mac or PC. We recommend checking out this post about entering and using DFU Mode on iPhone for the details.
Once you’ve got into DFU Mode, you have only one option—restore your iPhone to factory defaults. Select Restore iPhone, and your Mac or PC will automatically download and install the latest version of iOS, including the device firmware.
Again, you’ll lose your data, but you can get that back later via an iCloud or iTunes/Finder backup if your iPhone starts to work correctly.
Tips to Avoid Black Screen With Spinning Circle Issue
If force-restarting your iPhone or updating it in Recovery Mode helped, the pointers below should minimize the chances of the same issue occurring again.
Keep iOS Updated
New iOS updates come with numerous stability fixes and enhancements. If you haven’t updated your iPhone recently, go to Settings > General > Software Update and install any pending updates.
Update Third-Party Apps
If using third-party apps causes the iPhone to crash and get stuck, try applying the latest app updates. To do that, long-press the App Store icon, select Updates, and select Update All.
Free Up Internal Storage
An iPhone can also get stuck at a black screen with a loading circle if it’s close to running out of storage.
Go to Settings > General > iPhone Storage and use the various storage recommendations—delete videos, iMessage attachments, and so on— to free up space. You can also delete or offload unnecessary apps and reduce your iPhone’s Other storage.
Downgrade to Stable Channel
If you use a beta version of iOS, you must expect frequent system software crashes. Do yourself a favor by downgrading to the stable channel. Here’s what you should do to downgrade iOS.
Reset All Settings
Resetting the settings on your iPhone helps you deal with any corrupt configurations behind the black screen with a spinning circle issue. Go to Settings > General > Reset and select Reset All Settings to perform a settings reset.
Factory Reset iPhone
If your iPhone continues to get stuck after crashing, you must reset the device to factory settings. You can restore your data using a backup after that.
Start by creating an iCloud or a Finder/iTunes backup. Then, go to Settings > General > Reset and select Erase All Content and Settings to factory reset the iPhone.
iPhone Fully Loaded
Force-restarting or restoring your iPhone in Recovery/DFU Mode should fix the black screen with the loading circle issue. Make sure to go through the pointers above to prevent it from becoming a recurrent problem.
However, if none of the fixes helped, you must take your iPhone to a Genius Bar or Apple Store for assistance.
