LSUnusedResources

A Mac App to find unused images and resources in an Xcode project. It is heavily influenced by jeffhodnett‘s Unused, but 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.

Example

Usage

It’s an useful utility tool to check what resources are not being used in your Xcode projects. Very easy to use:

1. Click Browse.. to select a project folder.
2. Click Search to start searching.
3. Wait a few seconds, the results will be shown in the tableview.

Feature

Check Ignore similar name to ignore the resources which referenced by string concatenation, regex: ([-_]?\d+).

For example:

You import some resources like:

icon_tag_0.png
icon_tag_1.png
icon_tag_2.png
icon_tag_3.png

icon_title-0.png
icon_title-1.png
icon_title-2.png

icon_test0.png
icon_test1.png
icon_test2.png

And using in this way:

NSInteger index = random() % 4;
UIImage *img0 = [UIImage imageNamed:[NSString stringWithFormat:@"icon_tag_%d", index]];
	
// Or
UIImage *img1 = [self createImageWithPrefix:@"icon_title" concat:@"-" andIndex:index];

// Or
UIImage *img2 = [self createImageWithPrefix:@"icon_test" andIndex:index];

icon_tag_x.png, icon_title-x and icon_testx will be considered to be used, should not be shown as unused resource.

Installation

• Download: LSUnusedResources.app.zip
• Or build and run the project using Xcode.

How it works

1. Get resource files (default: [imageset, jpg, png, gif]) in these folders [imageset, launchimage, appiconset, bundle, png].
2. Use regex to search all string names in code files (default: [h, m, mm, swift, xib, storyboard, strings, c, cpp, html, js, json, plist, css]).
3. Exclude all used string names from resources files, we get all unused resources files.

Requirements

Requires OS X 10.7 and above, ARC.
