(Apps)由于系统软件的稳定性， 应用程序往往在 iPhone 和 iPad 上运行良好。
但是您仍然会遇到拒绝正常运行的奇怪应用程序。很少，问题可能严重到足以阻止它完全打开。有几个原因——例如错误、故障和冲突设置——通常会导致这种情况。
如果某个应用无法在您的 iPhone 或 iPad 上打开，或者它立即崩溃，下面的修复和建议应该可以帮助您重新启动并运行它。
强制退出应用程序并重试
当应用程序反复无法打开或在几秒钟后崩溃时，您必须在重新启动之前将其从 iPhone 或 iPad 的内存中强行删除。在大多数情况下，这应该允许应用程序毫无问题地加载。
首先从屏幕底部向上滑动以打开App Switcher。如果您使用带有Touch ID的 iPhone，请改为双击主(Home )屏幕按钮。然后，将有问题的应用程序向上拖出屏幕以强制退出它。
(Follow)然后从主(Home)屏幕或iPhone或 iPad 的应用程序库重新打开应用程序。(App Library of your iPhone)
重启 iPhone 或 iPad
您的下一步行动应该是重新启动 iPhone 或 iPad。这是解决阻止应用程序打开的随机故障的可靠方法。
前往“设置”(Settings )并点按“通用(General )” > “关机”(Shut Down)。然后向右滑动电源(Power )图标以关闭设备。
等待(Wait)30 秒，然后按住 iPhone 或 iPad 上的侧边(Side )按钮以将其重新启动。
强制重启 iPhone 或 iPad
如果 iPhone 或 iPad 在尝试打开应用程序后出现无响应，则必须强制重启设备。之后您可以尝试重新启动该应用程序。
根据设备型号，执行适当的按钮按下以触发强制重启。
iPhone 8 Series and Newer | iPads Without Home Button
快速按下并释放音量调高(Volume Up)按钮，按下并释放音量调低(Volume Down )按钮，然后按住侧面(Side )按钮，直到看到Apple标志。
仅限 iPhone 7 系列(iPhone 7 Series Only)
按住降低音量(Volume Down)和侧边(Side )按钮，直到看到Apple标志。
iPhone 6 Series and Older | iPads With Home Button
按住主(Home )屏幕按钮和侧边(Side )按钮，直到看到Apple标志。
更新应用程序
如果该应用程序仍然无法在您的 iPhone 或 iPad 上打开，您可能正在处理与软件相关的重大错误。更新它应该可以解决这个问题。
首先前往App Store。然后，搜索该应用程序并点击更新(Update )以将其更新到最新版本。
您还可以查看发行说明（位于应用程序应用商店页面(App Store)的新增功能( What’s New)部分下方），以验证最近的更新是否解决了该问题。
如果您在应用程序旁边没有看到更新按钮，请继续进行修复。(Update )
更新 iOS 和 iPadOS
iOS 和 iPadOS 的最新更新附带了错误修复，可以潜在地解决故障应用程序背后的潜在问题。
如果您处于主要系统软件版本（例如 iOS 14.0 或 iPadOS 14.0）的相对较新的迭代中，更新也很重要，因为漏洞和故障猖獗。
打开设置(Settings )应用程序，然后转到常规(General )>软件更新(Software Update)。如果您看到新的更新，请点击下载并安装(Download and Install)以应用它。
系统(System)软件更新也是更新邮件(Mail)、Safari和提醒(Reminders)等常用应用程序的唯一方法。
(Reset)通过设置应用程序(Settings App)重置或清除缓存(Cache)
iPhone 或 iPad 上的设置(Settings)应用程序可能包含重置应用程序或清除其缓存的选项。例如，如果Netflix无法打开，请转到“设置”(Settings ) > “ Netflix ”并激活“重置(Reset)”以将所有Netflix设置恢复为默认值。
如果应用程序由于设置冲突或缓存过时而拒绝打开，则最终可能会解决问题。
卸载或删除(Delete)应用程序(App)并重新安装(Reinstall)
卸载应用程序并重新安装它也可以帮助解决由安装损坏导致的持久性问题。首先(Start)转到Settings > General > iPhone Storage。然后，点击有问题的应用程序并选择卸载应用程序(Offload App)。
然后(Follow)重新启动您的 iPhone 或 iPad。然后，点击主(Home)屏幕中的应用程序图标以重新安装它。
如果失败，请尝试删除并重新安装应用程序(deleting and reinstalling the app)。但是，这也将删除与该应用程序相关的任何本地下载数据，即Netflix中的离线视频。
互联网连接故障排除
(Apps)如果无法连接到互联网， Discord和Netflix等应用程序可能无法打开或崩溃。在这种情况下，您可以执行以下操作：
检查服务器端问题
服务器端问题还可以阻止应用程序与 Internet 通信并阻止其打开。在这种情况下，您必须等到服务器重新联机。在Google上粗略搜索应该会显示应用程序或服务的服务器状态。
重置iPhone 或 iPad上的设置(Your)
如果上述修复均无效，请尝试重置 iPhone 或 iPad 上的设置。这应该可以解决由损坏的配置引起的问题。
首先转到Settings > General > Reset。然后，点击重置网络设置(Reset Network Settings)以将所有与网络相关的设置恢复为默认值。之后，您必须手动重新连接到Wi-Fi网络。(Wi-Fi)
如果重置网络设置没有帮助，您必须将所有与系统相关的设置重置为默认值。为此，请转到设置(Settings )>常规(General )>重置(Reset )，然后点击重置所有设置(Reset All Settings)。
您必须在重置过程后重新配置您的网络、隐私、可访问性和其他设置。
联系应用开发者
某些应用程序仍然可以拒绝打开，特别是如果应用程序有一段时间没有收到任何更新。最好的办法是将问题通知应用程序开发人员。您可以通过前往应用程序的App Store页面并选择“应用程序支持(App Support)”选项来做到这一点。此外，您可以通过电子邮件或社交媒体联系开发人员。
What To Do If An App Won’t Open on iPhone or iPad
Apps tend to run well on the iPhone and iРad, due to the stable nature of the ѕуstem software.
But you’ll still encounter the odd app that refuses to function correctly. Rarely, the issue can be severe enough to prevent it from opening altogether. Several reasons—such as bugs, glitches, and conflicting settings—often cause that.
If an app won’t open on your iPhone or iPad, or it crashes immediately, the fixes and suggestions below should help you get it up and running again.
Force-quit the App and Retry
When an app fails to open repeatedly or crashes after a few seconds, you must forcibly remove it from the iPhone or iPad’s memory before relaunching it. In most cases, that should allow the app to load without issues.
Start by swiping up from the bottom of the screen to open the App Switcher. If you use an iPhone with Touch ID, double-click the Home button instead. Then, drag the problematic app up and out of the screen to force-quit it.
Follow by reopening the app from the Home screen or the App Library of your iPhone or iPad.
Restart iPhone or iPad
Your next course of action should be to restart the iPhone or iPad. That’s a sure-fire way to resolve random glitches preventing an app from opening.
Go to Settings and tap General > Shut Down. Follow by sliding the Power icon to the right to turn off the device.
Wait for 30 seconds, and then hold down the Side button on the iPhone or iPad to boot it back up.
Force-Restart iPhone or iPad
If the iPhone or iPad appears unresponsive after attempting to open an app, you must forcibly restart the device. You can try relaunching the app after that.
Depending on the device model, perform the appropriate button presses to trigger a force-restart.
iPhone 8 Series and Newer | iPads Without Home Button
Quickly press and release the Volume Up button, press and release the Volume Down button, and press and hold the Side button until you see the Apple logo.
iPhone 7 Series Only
Press and hold both the Volume Down and the Side buttons until you see the Apple logo.
iPhone 6 Series and Older | iPads With Home Button
Press and hold both the Home and the Side buttons until you see the Apple logo.
Update the App
If the app still doesn’t open on your iPhone or iPad, you’re likely dealing with a major software-related bug. Updating it should fix that.
Start by heading over to the App Store. Then, search for the app and tap Update to bring it to the latest version.
You can also check the release notes (underneath the What’s New section of the app’s App Store page) to verify if a recent update has addressed the issue.
If you don’t see an Update button next to the app, continue with the fixes.
Update iOS and iPadOS
The latest updates for iOS and iPadOS come with bug fixes that can potentially resolve underlying issues behind a malfunctioning app.
It’s also crucial to update if you’re on a relatively new iteration of a major system software release—e.g., iOS 14.0 or iPadOS 14.0—due to the rampant bugs and glitches.
Open the Settings app and go to General > Software Update. If you see a new update, tap Download and Install to apply it.
System software updates are also the only way to update stock apps such Mail, Safari, and Reminders.
Reset or Clear Cache via Settings App
The Settings app on your iPhone or iPad may contain options to reset the app or clear its cache. For example, if Netflix won’t open, go to Settings > Netflix and activate Reset to revert all Netflix settings to defaults.
If an app refuses to open due to conflicting settings or an obsolete cache, that could end up fixing the issue.
Offload or Delete the App and Reinstall
Offloading an app and reinstalling it can also help fix persistent issues caused by a corrupt installation. Start by heading over to Settings > General > iPhone Storage. Then, tap the problematic app and select Offload App.
Follow by restarting your iPhone or iPad. Then, tap the app’s icon within the Home screen to reinstall it.
If that fails, try deleting and reinstalling the app. However, that will also remove any locally downloaded data related to the app—i.e., offline videos in Netflix.
Troubleshoot Internet Connectivity
Apps such as Discord and Netflix can fail to open or crash if they have trouble connecting to the internet. In that case, here are a few things that you can do:
Check for Server-Side Issues
Server-side issues can also prevent an app from communicating with the internet and prevent it from opening. In that case, you must wait it out until the servers come back online. A cursory search on Google should reveal the server status for an app or service.
Reset the Settings on Your iPhone or iPad
If none of the fixes above worked, try resetting the settings on your iPhone or iPad. That should resolve issues caused by corrupt configurations.
Start by heading over to Settings > General > Reset. Then, tap Reset Network Settings to revert all network-related settings to their defaults. You’ll have to reconnect to Wi-Fi networks manually after that.
If resetting network settings didn’t help, you must reset all system-related settings to their defaults. To do that, go to Settings > General > Reset and tap Reset All Settings.
You must re-configure your network, privacy, accessibility, and other settings after the reset procedure.
Contact the App Developer
Some apps can still refuse to open, especially if the app hasn’t received any updates in a while. Your best bet is to notify the app developer of the problem. You can do that by heading over the app’s App Store page and selecting the App Support option. Additionally, you can contact the developer via email or social media.
