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！

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

你可以用内置的截图工具记录屏幕的一部分:

按Shift-Command-5显示控制面板。 选择。 选择要记录的屏幕的一部分。这就是iPhone模拟器。 单击，停止录制。 一个缩略图将出现在屏幕的右下角。您可以在保存之前编辑它。

如果您希望可视化鼠标单击，请在步骤1之后选择“选项”控件并启用“显示鼠标单击”。

您可以结合QuickTime播放器+ iMovie(免费)

首先从xcode中选择你想要的模拟器，并使用QuickTime Player记录屏幕。然后用iMovie制作App Preview，最后用Safari浏览器上传视频。很简单……：）

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
