文档目录是否有Xcode构建设置参考？

Question

I'm looking to see if any XCode build setting reference such as ${PROJECT_NAME} exists for the document directory. I have some files saved to the document directory and I would like to run a script that would target that file. The document directory is from:

NSArray *documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentDirectory = documentDirectories[0];

I searched through Apple's docs but maybe I missed it.

For example, if there is a "MyNotes.txt" in the iOS App document directory, I would like to run a script targeting that file (copy and pasting it to another folder).

Thanks.

No, there's no Xcode build setting for the document directory. You can add a empty Run Script to your build phases and check “Show environment variables in build log” to verify.

You can figure out the document directory by using the simctl command and then checking a bunch of plists. It's a bit roundabout. For example, this script finds the directory for an app with bundle identifier com.dqd.test , in the currently-booted simulated device:

#!/bin/bash

bundle=com.dqd.test

appdir=$(xcrun simctl get_app_container booted "$bundle")
appdataparentdir="${appdir%%/data/Containers/Bundle/*}"/data/Containers/Data/Application
for dir in "$appdataparentdir"/*; do
    if plutil -extract MCMMetadataIdentifier xml1 -o - "$dir/.com.apple.mobile_container_manager.metadata.plist" | grep ">$bundle<" >/dev/null; then
        break
    fi
    dir=
done

if [ "$dir" != "" ]; then
    echo "$dir/Documents"
fi

Result:

:; ./getdocdir
/Users/mayoff/Library/Developer/CoreSimulator/Devices/3699C4CE-D6F3-4E6E-B1AC-0B35D78BFD80/data/Containers/Data/Application/32068FBC-6191-4F5E-B18F-D47D8778D3BE/Documents

Note that each simulated device has its own UUID, its own subdirectory in the under CoreSimulator/Devices , and its set of containers, so the output will change if you boot a different simulated device.
