对于iOS 7，我做了以下操作:

复制照片到这两个文件夹:

~/Library/Application Support/iPhone Simulator/6.1/Media/DCIM/100APPLE
~/Library/Application Support/iPhone Simulator/7.0/Media/DCIM/100APPLE

只删除这4个文件(以避免重新启动时重复):

~/Library/Application Support/iPhone Simulator/6.1/Media/PhotoData/Photos.sqlite-shm
~/Library/Application Support/iPhone Simulator/6.1/Media/PhotoData/Photos.sqlite-wal
~/Library/Application Support/iPhone Simulator/7.0/Media/PhotoData/Photos.sqlite-shm
~/Library/Application Support/iPhone Simulator/7.0/Media/PhotoData/Photos.sqlite-wal

只需将图像拖到iPhone模拟器。

如果你需要导入不止一、两张照片，那就看看我写的这篇文章。它描述了一种简单的方法来执行批量导入照片，适用于iOS 4.x。

对于iOS 4.2，我必须创建100APPLE文件夹并重新启动模拟器，然后它就工作了。

为此我编写了一个bash脚本。 检查链接[1]

#!/bin/bash

# Imports pictures into all iOS simulators.

path_to_pic="src/ios/pictures/"

mkdir -p /Users/$(whoami)/Library/Application\ Support/iPhone\ Simulator/{5.0,5.1,6.0,6.1}/Media/DCIM/100APPLE/
find ~/Library/Application\ Support/iPhone\ Simulator/ -type d -name '100APPLE' -exec cp /Users/$(whoami)/$path_to_pic/* {} \;
