Have a look at the LLVM/Clang Static Analyzer

The LLVM/Clang static analyzer is a standalone tool that find bugs in C and Objective-C programs and it is very early in development.

A static analyzer based on clang. The goal of the Clang project is to create a new C, C++, Objective C and Objective C++ front-end for the LLVM compiler.

Edit

Clang has now been integrated into Xcode and can easily be run as a menu option "Build & Analyse"

The above link is 404'ed, for finding information about Clang / LLVM static analysis, I recommend reading [this](https://clang.llvm.org/docs/UsersManual.html#controlling-static-analyzer-diagnostics) and then `jmp` to [this](https://clang-analyzer.llvm.org/) – ipatch May 31 '18 at 19:46

It's worth mentioning OCLint too. It covers some things not touched by the Clang analyser, such as:

Complicated code - high cyclomatic complexity and NPath complexity
Code smells - long method, long parameter list, redundant code

Check out the home page for more details.

is there any tutorials for OCLint? I can't find anything better than oclint --help. – clopez Nov 15 '12 at 15:27

I know it is an old question, but I will add another one static analysis tool here for the sake of completeness, Infer, from Facebook

You can see their home page, works with iOS and Android projects, and spare Obj-C/Java/C files

There is also the commercial tool FauxPas, which catches a lot of code smells, but also stuff like unused graphics, translation format argument mismatch, etc.

It’s not super cheap, but I‘m a happy user. There's a time-limited trial version available, which is fully functional, as far as I know.

Is it OK to link to commercial tools? I’ve omitted the link both because I’m on mobile and because I’m not sure. – fzwo Mar 19 '18 at 11:32

Generally, yes. – ctietze May 30 '18 at 05:14

For simple syntax stuff like enforcing number of line breaks, sorting imports, etc., also have a look at Clang Format. The easiest way to install is probably via Homebrew.
