值得注意的是，在我至少使用的模拟器版本(12.5)中，“截图”和“保存屏幕”选项之间是不同的——截图保存到设备(在照片应用程序中找到)，而单击“保存屏幕”按钮会在Mac上生成图像。

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”

我在这里找到的

它看起来像最新的Xcode(我使用v4.2.1)有一个错误保存屏幕截图从iOS模拟器。即使按了文件>保存屏幕截图，我在桌面上也找不到任何图像文件。最近，我注意到一款很棒的iOS-Simulator Cropper软件。它允许您使用不同的设置从模拟器捕获图像。

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

我浏览了所有我找不到截图保存在哪里的帖子…… 所以，我只是使用command+shift+4，释放键后，你会看到一个牛眼在你的鼠标指针。单击并拖动要复制的屏幕部分。一旦释放你的鼠标点击图像将存储在你的桌面。比弄清楚模拟器在哪里存储截图要好。
