关于无用图片资源
LSUnusedResources
LSUnusedResources 感谢改工具开发者 GitHub链接https://github.com/tinymind/LSUnusedResources
A Mac App to find unused images and resources in an XCode project. It is heavily influenced by jeffhodnett‘sUnused, 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.
Usage
It's an useful utility tool to check what resources are not being used in your Xcode projects. Very easy to use:
ClickBrowse..to select a project folder.
ClickSearchto start searching.
Wait a second, the results will be shown in the tableview.
Feature
CheckIgnore similar nameto ignore the resources which referenced by string concatenation.
For example:
You import some resources like:
icon_tag_0.png
icon_tag_1.png
icon_tag_2.png
icon_tag_3.png
And using in this way:
NSIntegerindex = random() %4;UIImage*img = [UIImageimageNamed:[NSStringstringWithFormat:@"icon_tag_%d", index]];
icon_tag_x.pngshould not be shown as unused resource, we should ignore them.
Installation
Download:LSUnusedResources.app.zip
Or build and run the project using XCode.
Requirements
Requires OS X 10.7 and above, ARC.
关于没有使用到的类文件, 使用前实现备份
!!!!!! 如果你项目中有使用到xib和storyboard 一定要注意，这个工具并不检测storyboard，坑啊！回过头来我才知道为啥有的界面app会直接挂掉，因为找不到相关类文件呀！还要一步步检测 ，慎重使用！
