YouTube 是否无法在您的 iPad、iPad (Does YouTube)Air或 iPad Pro上进入全屏模式？还是视频在全屏模式下卡住或渲染不正确？
YouTube应用程序及其移动网站YouTube.com上偶尔会出现全屏问题。通过以下修复工作以解决它们。
尝试其他手势
如果YouTube(YouTube)视频窗格右下角的方形全屏图标没有响应，请尝试使用这些手势。(Full-Screen)
- Pinch Out：将两根手指放在视频窗格上，然后将它们分开以进入全屏模式。
- Pinch In：将两根手指分开并拉入以退出全屏模式。
根据浏览器的不同，上述手势可能不适用于 iPad 上的 YouTube 移动网站。相反，如果您使用鼠标或触控板进入和退出全屏模式，请双击视频窗格。
强制退出 YouTube
在 iPad上解决YouTube全屏问题（或与 YouTube 相关的任何其他问题(other issues with YouTube)）的最佳方法是强制退出YouTube应用并重新启动它。
为此，请打开App Switcher（从屏幕底部向上滑动）并将YouTube卡拖到屏幕顶部。然后，重新打开YouTube应用并检查全屏模式是否有效。
如果您的网络浏览器出现问题，请尝试在新标签页中关闭并打开YouTube 。如果这不起作用，请强制退出并重新启动浏览器。
清除浏览器缓存
损坏的浏览器缓存也可能导致YouTube出现异常行为，因此请尝试将其删除。在Safari上，打开设置(Settings)应用程序并选择Safari >清除历史记录和网站数据(Clear History and Website Data)。
如果您使用 Chrome，请打开Chrome 菜单(menu)并转到设置(Settings)>隐私(Privacy)>清除浏览数据(Clear Browsing Data)。然后，将时间范围(Time Range )设置为所有时间(All Time)，选择Cookies、站点数据(Cookies, Site Data,)和缓存图像和文件( Cached Images and Files)类别，然后点击清除浏览数据( Clear Browsing Data)。
禁用内容拦截器
Safari 中的内容阻止扩展也可能会导致(Content blocking extensions in Safari)YouTube出现全屏问题。点击URL栏左侧的AA图标，然后选择(AA)关闭内容阻止(Turn off Content Blockers)程序以在没有它们的情况下加载站点。
如果这有帮助，您可以将Safari配置为在默认情况下加载YouTube而没有内容阻止程序。再次打开AA菜单，点击网站设置(Website Settings)，然后关闭使用内容拦截( Use Content Blockers)器旁边的开关。
更新 YouTube
在 iPad 上使用过时版本的YouTube应用程序肯定会导致播放问题和其他异常。因此，打开App Store并搜索YouTube。如果您看到新的更新，请点击更新(Update)。
同样，如果您继续遇到 YouTube 移动网站的全屏问题，请更新您的浏览器。如果您使用Chrome(Chrome)或Firefox等第三方浏览器，您可以通过App Store执行更新。如果您使用Safari，则必须更新 iPad 的系统软件（更多内容见下文）。
重启 iPad
如果YouTube 上(YouTube)的全屏问题仍然存在，最好重新启动 iPad。打开设置(Settings)应用程序，点击常规(General)>关机(Shut Down)，然后向右拖动电源滑块。(Power)屏幕变暗后，按住侧边(Side)按钮，直到看到Apple标志。
强制重启 iPad
如果YouTube卡在全屏模式并导致您的 iPad 死机，您必须强制重启系统软件。立即快速连续按下并释放提高音量(Volume Up)和降低音量(Volume Down)按钮，然后立即按住侧面(Side)按钮，直到看到Apple标志。如果您使用带有主(Home)屏幕按钮的 iPad，则必须同时按住侧边(Side)按钮和主(Home)屏幕按钮，直到设备重新启动。
更新 iPad
YouTube 在全屏模式下的困难可能是由于 iPadOS 的潜在问题造成的，尤其是当您在使用Netflix等其他视频流媒体服务时也遇到类似问题时。您可以尝试通过更新 iPad 来解决此问题。前往“设置”(Settings) > “通用(General)” > “软件更新”(Software Update)，然后轻点“下载并安装(Download and Install)”以安装任何待处理的 iPadOS 更新。
卸载/重新安装 YouTube
解决YouTube(YouTube)全屏问题的另一种方法是删除并重新安装 YouTube 应用(remove and reinstall the YouTube app)。为此，请转到设置(Settings)>常规(General)> App Store > YouTube，然后点击删除应用程序( Delete App)或卸载应用程序(Offload App)（如果您有任何要保留的下载，请选择后一个选项）。然后，通过 App Store重新下载YouTube 。
重置 iPad 设置
如果上述修复均无济于事，您必须重置 iPad 上的所有设置(reset all settings on the iPad)。这应该可以解决阻止 YouTube 正常工作的任何损坏或冲突的系统相关配置。
因此，打开“设置”(Settings)应用程序并转到“通用(General)” > “传输或重置 iPad( Transfer or Reset iPad ) ” > “重置(Reset)” > “重置所有设置”(Reset All Settings)。然后，输入您的设备密码并再次点击重置所有设置(Reset All Settings)进行确认。
iPad 重新启动后，重新连接到任何无线网络并重新配置您的隐私、安全和可访问性首选项。之后检查您是否可以在全屏模式下使用YouTube 。
全屏体验最佳
YouTube在 iPad 上的全屏问题通常源于与软件相关的随机故障，因此强制退出YouTube应用或重新启动系统软件等快速修复将在大多数情况下帮助您解决这些问题。如果没有，其他修复肯定会。
无论如何，请让YouTube、您的浏览器和 iPadOS 保持最新状态，以尽量减少今后遇到类似问题的机会。
How to Fix YouTube Full Screen Not Working on iPad
Does YouTubе fail to enter full-screen mode on your iРad, iPаd Air, or iPad Pro? Or do videos get stuck or render incorrectly in full-screen mode?
Full-screen issues can occasionally crop up on the YouTube app and its mobile site at YouTube.com. Work your way through the fixes below to resolve them.
Try Alternative Gestures
If the square-shaped Full-Screen icon at the lower right corner of the YouTube video pane appears unresponsive, try these gestures instead.
- Pinch Out: Place two fingers together on the video pane and pull them apart to enter full-screen mode.
- Pinch In: Place two fingers apart and pull them in to exit full-screen mode.
Depending on the browser, the gestures above may not work with YouTube’s mobile site on iPad. Instead, double-click the video pane if you use a mouse or trackpad to enter and exit full-screen mode.
Force-Quit YouTube
The best way to fix YouTube full-screen problems—or any other issues with YouTube for that matter—on iPad involves force-quitting the YouTube app and relaunching it.
To do that, open the App Switcher (swipe up from the bottom of the screen) and drag the YouTube card to the top of the screen. Then, re-open the YouTube app and check if full-screen mode works.
If the problem occurs on your web browser, try closing and opening YouTube in a new tab. If that doesn’t do anything, force quit and relaunch the browser.
Clear Browser Cache
A corrupt browser cache can also cause YouTube to behave unusually, so try deleting it. On Safari, open the Settings app and select Safari > Clear History and Website Data.
If you use Chrome, open the Chrome menu and go to Settings > Privacy > Clear Browsing Data. Then, set the Time Range to All Time, select the Cookies, Site Data, and Cached Images and Files categories, and tap Clear Browsing Data.
Disable Content Blockers
Content blocking extensions in Safari can also create full-screen issues with YouTube. Tap the AA icon at the left of the URL bar and select Turn off Content Blockers to load the site without them.
If that helps, you can configure Safari to load YouTube without content blockers by default. Open the AA menu again, tap Website Settings, and turn off the switch next to Use Content Blockers.
Update YouTube
Using an outdated version of the YouTube app on your iPad is a surefire way to cause playback issues and other anomalies. So, open the App Store and search for YouTube. If you see a new update, tap Update.
Likewise, update your browser if you continue to experience full-screen issues with YouTube’s mobile site. If you use a third-party browser such as Chrome or Firefox, you can perform the update via the App Store. If you use Safari, you must update the iPad’s system software (more on that further below).
Restart iPad
If full-screen issues on YouTube persist, it’s a good idea to restart your iPad. Open the Settings app, tap General > Shut Down, and drag the Power slider to the right. After the screen goes dark, hold down the Side button until you see the Apple logo.
Force-Restart iPad
If YouTube gets stuck in full-screen mode and causes your iPad to freeze, you must force-restart the system software. Immediately press and release the Volume Up and Volume Down buttons in quick succession, and then immediately press and hold the Side button until you see the Apple logo. If you use an iPad with a Home button, you must instead press and hold both the Side and Home buttons until the device restarts.
Update iPad
YouTube’s difficulties with full-screen mode could result from underlying issues with iPadOS, especially if you also run into similar problems with other video streaming services such as Netflix. You can attempt to fix that by updating your iPad. Go to Settings > General > Software Update and tap Download and Install to install any pending iPadOS updates.
Uninstall/Reinstall YouTube
Another way to fix full-screen issues with YouTube is to remove and reinstall the YouTube app. To do that, go to Settings > General > App Store > YouTube and tap Delete App or Offload App (pick the latter option if you have any downloads you want to keep). Then, redownload YouTube via the App Store.
Reset iPad Settings
If none of the fixes above help, you must reset all settings on the iPad. That should resolve any corrupt or conflicting system-related configurations preventing YouTube from working correctly.
So, open the Settings app and go to General > Transfer or Reset iPad > Reset > Reset All Settings. Then, enter your device passcode and tap Reset All Settings again to confirm.
Once your iPad reboots, reconnect to any wireless networks and reconfigure your privacy, security, and accessibility preferences. Check if you can use YouTube in full-screen mode after that.
Best Experienced In Full Screen
YouTube’s full-screen issues on iPad generally stem from random software-related glitches, so quick fixes such as force-quitting the YouTube app or restarting the system software will help you resolve them most of the time. If not, the other fixes definitely will.
Regardless, keep YouTube, your browser, and iPadOS up-to-date to minimize the chances of running into similar issues going forward.
