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

它们存储在:

~/Library/Application\ Support/Developer/Shared/Xcode/Screenshots

我喜欢把它们放在我的Dropbox里，这样我的其他设备上也能看到它们。

cd ~/Library/Application\ Support/Developer/Shared/Xcode/
mkdir ~/Dropbox/Pictures/xcode/
mv Screenshots/* ~/Dropbox/Pictures/xcode/
rm -rf Screenshots
ln -sf ~/Dropbox/Pictures/xcode/ Screenshots

这将创建一个符号链接到你的Dropbox在图片/xcode

按下命令+ s，截取屏幕截图，它将存储在桌面参见示例

我在这里找到的

图书馆/开发/ CoreSimulator /设备/ (UDID) /数据/媒体/ DCIM

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。

我发现一个很有用的方法就是用聚光灯搜索快捷键CMD+空格然后输入文字“截屏”或者“ios模拟器截屏”

如果它不在最初的搜索屏幕上，你总是可以使用列表中第一个显示All in Finder选项

这不仅第一次有效，而且每次都有效，而且当我忘记之前的屏幕截图移动到哪里时，它也会提醒我。
