Are there any good tools to collect Objective-C metrics?

Question

I'm using Jenkins for CI on iOS projects and want to collect some software metrics on them. But the only tool I was able to find was CLOC which only counts lines of codes (LOCs). Nevertheless it's better than nothing.

What I really want to count are methods, classes, calls to other classes etc. (to do the fancy cyclomatic complexity stuff).

Perhaps I'm missing some tools, let me know, if I do.

OCLint?

From oclint.org:

OCLint is a static code analysis tool for improving quality and reducing defects by inspecting C, C++ and Objective-C code and looking for potential problems like:

Possible bugs - empty if/else/try/catch/finally statements

Unused code unused local variables and parameters

Complicated code - high cyclomatic complexity, NPath complexity and high NCSS

Redundant code - redundant if statement and useless parentheses

Code smells - long method and long parameter list

Bad practices - inverted logic and parameter reassignment ...

OCLint is outputing: _This binary is no longer under maintenance by OCLint team. Please consider using xcpretty (https://github.com/supermarin/xcpretty) instead!_ – Cœur May 11 '16 at 05:27
@Cœur I'm also facing the same issue. Do you have any update on this? – Akshay May 02 '17 at 12:41
@Akshay I simply use Lizard. – Cœur May 02 '17 at 13:07

You can try XClarify, a pretty complete objective-c code analyzer, and it's free for open source contributors.

Beyond lines of code and test coverage, I'm not sure there are any such tools yet for Obj-C. I suspect we'll see some soon given the influx of devs from other platforms who use metrics, but in my 7 years as an Obj-C dev I haven't heard of anyone having a tool for collecting them. Of course it'd be good to be proved wrong :)

ProjectCodeMeter measures flow complexity (similar to McCabe cyclomatic complexity) on Objective-C code, but it doesn't count methods and classes though..

I don't see a Mac version, looks like windows only. – Dan Power Sep 23 '12 at 08:48

I use few tools for gathering code quality metrics:

OCLint - Gather some metrics, like cyclomatic complexity, and enforce best practice - http://oclint.org
Simian - Similarity Analyser - http://www.harukizaemon.com/simian/
Clang analyzer - Same tool as in Xcode (Product -> Analyze), seems like a bit outdated though useful too. To perform it on CI see that: http://clang-analyzer.llvm.org/scan-build.html
Coveralls - nice tools for visualization of unit test coverage - https://coveralls.io

I've found recently that it exists free plugin for SonarQube - https://github.com/octo-technology/sonar-objective-c but it's not really feature-rich. Official one is here: http://www.sonarsource.com/products/plugins/languages/objective-c/

I just stumbled upon Xcode Statistician (link seems to be dead), but haven't tried it yet. The zip archive can be downloaded directly.

I just tried it. Fairly basic stats: LOC per source file, classes, etc. However, no cyclomatic complexity, no methods per class, or any of the more truly useful stats. More disappointingly, it doesn't automatically traverse subfolders. Although the doc refers to scanning your project, it only works on the source files in the current folder. – Phil Nov 14 '13 at 15:29
That link is broken now. – Carlos Macasaet Jan 10 '16 at 23:55

@CarlosMacasaet Yeah, looks like it. But you can still download the zip archive via: http://www.literatureandlatte.com/freestuff/XcodeStatistician.zip – Jens Kohl Jan 11 '16 at 16:29

What I really want to count are methods, classes

nnnot rrreallly.... you can parse the xcode indexes or the output of nm -- or run doxygen.

calls to other classes etc

gcov -- or run doxygen
