You can make a shell script that <code>grep</code> your source code and compare the founded images with your project folder.

Here the man(s) for <a href="http://unixhelp.ed.ac.uk/CGI/man-cgi?grep" rel="nofollow"><code>GREP</code></a> and <a href="http://unixhelp.ed.ac.uk/CGI/man-cgi?ls" rel="nofollow"><code>LS</code></a> 

Easily you can loop all of your source file, save images in array or something equals and use 

<code>cat file.m | grep [-V] myImage.png</code> 

With this trick, you can search all images in your project source code!!

hope this helps!

I tried Roman's solution, and I added a few tweaks to handle retina images. It works well, but remember that image names can be generated programmatically in code, and this script would incorrectly list these images as unreferenced. For example, you might have 

<code>NSString *imageName = [NSString stringWithFormat:@"image_%d.png", 1];</code> 

This script will incorrectly think <code>image_1.png</code> is unreferenced.

Here's the modified script:

<pre><code>#!/bin/sh
PROJ=`find . -name '*.xib' -o -name '*.[mh]' -o -name '*.storyboard' -o -name '*.mm'`

for png in `find . -name '*.png'`
do
 name=`basename -s .png $png`
 name=`basename -s @2x $name`
 if ! grep -qhs "$name" "$PROJ"; then
 echo "$png"
 fi
done
</code></pre>

I made a very slight modification to the excellent answer provided by @EdMcManus to handle projects utilizing asset catalogs.

It is heavily influenced by jeffhodnett‘s <a href="http://jeffhodnett.github.io/Unused/" rel="noreferrer">Unused</a>, but honestly Unused is very slow, and the results are not entirely correct. So I made some performance optimization, the search speed is more faster than Unused.

Using the other answers, this one is a good example of how to ignore images on two directories and do not search occurrences of the images on the pbxproj or xcassets files (Be careful with the app icon and splash screens). Change the * in the --ignore-dir=*.xcassets to match your directory:

<pre><code>#!/bin/bash

for i in `find . -not $ -path ./Frameworks -prune $ -not $ -path ./Carthage -prune $ -not $ -path ./Pods -prune $ -name "*.png" -o -name "*.jpg"`; do 
 file=`basename -s .jpg "$i" | xargs basename -s .png | xargs basename -s @2x | xargs basename -s @3x`
 result=`ack -i --ignore-file=ext:pbxproj --ignore-dir=*.xcassets "$file"`
 if [ -z "$result" ]; then
 echo "$i"

Has anyone a one-line to find unused images in an Xcode project? (Assuming all the files are referenced by name in code or the project files - no code generated file names.)

These files tend to build up over the life of a project and it can be hard to tell if it's safe to delete any given png.

How to find unused images in an Xcode project?

服务器

Xcode

有没有人可以在Xcode项目中找到未使用的图像？(假设在代码或项目文件中按名称引用所有文件-没有代码生成的文件名。)这些文件往往会在项目的整个生命周期中积累起来，很难判断删除任何给定的png是否安全。
