我正在使用 Xcode 3.2.4 并设置了 Clang 静态分析器功能以使用较新的二进制版本，详情如下：http: //clang-analyzer.llvm.org/xcode.html

（基本上使用set-xcode-analyzer命令行实用程序来更改 Xcode 用于构建和分析的静态分析器副本。）

我想不通的是如何设置该二进制文件以使用额外的检查，例如通过 Xcode 使用二进制文件时的 -analyzer-check-objc-missing-dealloc，详见此处： http: //loufranco.com/blog/文件/scan-build-better-than-build-analyze.html和 scan-build --help。

    AVAILABLE ANALYSES (multiple analyses may be specified):

 (+) -analyzer-check-dead-stores
     -analyzer-check-llvm-conventions
 (+) -analyzer-check-objc-mem
 (+) -analyzer-check-objc-methodsigs
     -analyzer-check-objc-missing-dealloc
 (+) -analyzer-check-objc-unused-ivars
 (+) -analyzer-check-security-syntactic

 NOTE: "(+)" indicates that an analysis is enabled by default unless one
       or more analysis options are specified

通过 Xcode 使用时，如何将额外的选项传递给二进制文件？

Upon further investigation, it seems the best way to do this is to use a couple of entries in the Target Build Info, rather than the set-xcode-analyzer command line tool.

Add a User-defined setting, CC, containing the full path to the newer build of the binary, as follows (note that the /bin/clang on the end of the path):

CC = /Path/To/Folder/With/Clang/checker-244/bin/clang

Then in the Other Warning Flags entry add as many of the additional checks as you want, as follows:

WARNING_CFLAGS = -Xanalyzer -analyzer-check-llvm-conventions -Xanalyzer -analyzer-check-objc-missing-dealloc

Each is preceded by the argument -Xanalyzer which indicates that the next argument should be passed to the analyzer.

More on this can be found here: Mac OS X Developer Tools Manual Page.

Then, when you do a Build and Analyze in Xcode you should be using the external, newer binary running the additional checks.

The accepted answer no longer works (Xcode 4)

The format of Xcode's build file means you have to do it like this:

WARNING_CFLAGS = "-Xanalyzer -analyzer-check-llvm-conventions -analyzer-check-objc-missing-dealloc"

NB: the quotes surrounding the entire XAnalyzer phrase.
