现在我们可以向App Store提交应用的视频预览。根据苹果公司的说法，我们应该在iOS8设备和OSX 10.10设备上这样做。问题是你必须拥有所有不同的设备(4英寸、4.7英寸、5.5英寸和iPad)。
还有别的选择吗?
我想拍一段模拟器的视频。问题是，当以100%分辨率显示时，设备屏幕比我的全高清显示器还大。任何解决方案，可以捕捉视频从模拟器的全分辨率?
编辑: 因为很多人都在回答我没有问的问题让我说 记录一个设备大小并缩放它不是我要求的 我问的不是如何录制应用预览 -我问的不是你怎么做预告片;
我想问的是，如果模拟器无法在屏幕上显示，你能否以100%分辨率录制视频?

给喜欢使用ZSH函数的用户的提示。您可以通过添加一个与@Tikhonov Alexander的答案相同的函数来简化事情。
你可以这样开始:
edit ~/.zshrc
进入你的终端。
然后在文件中添加这个函数。
function recsim() {
echo -n "Use CTRL+C to stop recording";
xcrun simctl io booted recordVideo --codec=h264 --mask=black "$1.mp4";
}
要使用，输入如下内容:
recsim appPreview
进入你的终端窗口。注意:添加功能后必须重新启动终端才能工作。
此函数改编自Antoine Van Der Lee关于如何在bash中实现此功能的博客文章，可以在这里找到。

我也面临着同样的问题。它有一个非常简单的解决方案，对我来说很管用。只需遵循以下步骤:
1.在iMovie中制作一个预览视频。
2.使用共享文件选项导出视频。选择1920x1080，因为它可以用于5S和6 +。
3.下载Appshow for Mac by techsmith (https://www.techsmith.com/techsmith-appshow.html)。它是专门为制作应用程序预览视频。但我不推荐它制作视频，而只是用于导出。
4.选择一个新的应用预览视频，并通过选择更少的帧来自定义它，你可以稍后删除。
5.将iMovie视频导入这个模板。在右上角，你可以选择任何你想要的分辨率，appshow有应用程序预览所需的所有分辨率。
6.最后，只需选择设备并导出所选分辨率的视频。
You can use the QuickTime screen recording and the iOS Simulators to do your video recordings. The tricky thing here is to get the correct size so that iMovie can detect the output resolution when you go to export the AppPreview. I haven't found a way to select the output res in iMovie so if must detected by the format of the media you are using. It may take you several tries but it's doable. It's one of those: do I have $300 for FinalCut Pro or do I have an hour or so of my time? You only need three recordings as mentioned above. I could actually do two of them on devices because I have them but I don't have an iPhone 6 (yet ... :) ). I also like the simulators because you can use something like SimFinger to simulate gestures and pressing of buttons.
好运！
对于Xcode 8.2或更高版本
您可以使用xcrun simctl(一个命令行实用程序来控制模拟器)拍摄模拟器的视频和屏幕截图
在模拟器上运行应用程序 打开终端 执行命令 截图 xxrun simctl IO启动截图<filename>。<文件扩展名> 例如: xrun simctl io启动截图myScreenshot.png 拍一段视频 xrun simctl io boot recordVideo <filename>. txt<文件扩展名> 例如: xrun simctl io启动recordVideo appVideo.mov 按“ctrl + C”停止录像。
所创建文件的默认位置是当前目录。
Xcode 11.2及以后版本提供了额外的选项。
来自Xcode 11.2 Beta版本说明
simctl视频记录现在产生更小的视频文件，支持HEIC 压缩，并利用硬件编码支持的地方 可用。此外，可以在iOS 13上录制视频，tvOS 13, watchOS 6设备已恢复。
你可以使用额外的标志:
xcrun simctl io --help
Set up a device IO operation.
Usage: simctl io <device> <operation> <arguments>
...
recordVideo [--codec=<codec>] [--display=<display>] [--mask=<policy>] [--force] <file or url>
Records the display to a QuickTime movie at the specified file or url.
--codec Specifies the codec type: "h264" or "hevc". Default is "hevc".
--display iOS: supports "internal" or "external". Default is "internal".
tvOS: supports only "external"
watchOS: supports only "internal"
--mask For non-rectangular displays, handle the mask by policy:
ignored: The mask is ignored and the unmasked framebuffer is saved.
alpha: Not supported, but retained for compatibility; the mask is rendered black.
black: The mask is rendered black.
--force Force the output file to be written to, even if the file already exists.
screenshot [--type=<type>] [--display=<display>] [--mask=<policy>] <file or url>
Saves a screenshot as a PNG to the specified file or url(use "-" for stdout).
--type Can be "png", "tiff", "bmp", "gif", "jpeg". Default is png.
--display iOS: supports "internal" or "external". Default is "internal".
tvOS: supports only "external"
watchOS: supports only "internal"
You may also specify a port by UUID
--mask For non-rectangular displays, handle the mask by policy:
ignored: The mask is ignored and the unmasked framebuffer is saved.
alpha: The mask is used as premultiplied alpha.
black: The mask is rendered black.
现在你可以在jpeg中截图，带掩码(用于非矩形显示)和一些其他标志:
xrun simctl IO启动截图——type=jpeg——mask=黑色截图
Taking a Screenshot or Recording a Video Using the Command Line You can take a screenshot or record a video of the simulator window using the xcrun command-line utility. Launch your app in Simulator. Launch Terminal (located in /Applications/Utilities), and enter the appropriate command: To take a screenshot, use the screenshot operation: xcrun simctl io booted screenshot You can specify an optional filename at the end of the command. To record a video, use the recordVideo operation: xcrun simctl io booted recordVideo <filename>.<extension> To stop recording, press Control-C in Terminal. Note: You must specify a filename for recordVideo. The default location for the created file is the current directory. For more information on simctl, run this command in Terminal: xcrun simctl help For more information on the io subcommand of simctl, run this command: xcrun simctl io help
