我有完全相同的问题，但我发现虽然(命令+s)没有保存图像到桌面(命令+Ctrl+C)复制的截图到剪贴板。然后，您可以使用预览打开并保存截图。

在Organizer视图中右键单击截图，选择“Show In Finder…”。

这将为您打开Finder中的截图文件夹。

If you create screenshots from within the simulator using File -> Save Screen Shot (Command-S), those files end up on the Desktop as something like: iOS Simulator Screen shot Apr 22, 2012.png. Under Xcode 6 & newer, device screenshots taken with the "Take Screenshot" button in the Xcode "Devices" menu will end up on the desktop. Look for a file named "Screen Shot 2014-MM-DD at HH.MM.SS.png" For Xcode 5 & older, if you create screenshots from within Xcode (Organizer), you'll find these in ~/Library/Application Support/Developer/Shared/Xcode/Screenshots. To take screenshots from the Xcode (Organizer) you need to have hardware device attached. The organizer does not appear to take screenshots from the simulator.

在Xcode之外:

If you create screenshots using the Finder (command-shift-3 or command-shift-4), these also end up on the Desktop as something like: "Screen Shot 2012-04-22 at _ AM.png" If you use the Grab application (found in /Application/Utilities), you can save those files anywhere you decide. :-) If you have saved a screenshot to the Photos library from within your app, for example with UIGetScreenImage and UIImageWriteToSavedPhotosAlbum, they end up at ~/Library/Application Support/iPhone Simulator/***version***/Media/DCIM/100APPLE

它们被保存到桌面，寻找一个PNG文件，命名约定为“iOS模拟器屏幕截图[DATE].png”

按下命令+ s，截取屏幕截图，它将存储在桌面参见示例

对于那些没有保存到桌面的人来说，可以试试这个位置:

~ /图书馆/开发/ CoreSimulator /设备/

会有一个随机哈希列表，每一个都是一个模拟器。 按修改日期排序，然后输入最近的文件夹，然后转到:

数据/媒体/ DCIM / 100苹果

你的照片和截图应该在那里:)
