how can I enable alpha/debug checker or my own checker

i write a new checker named test.NewChecker.it works in cmd:**clang -cc1 -analyze -analyzer-checker=**test.NewChecker test.c
but cmd:./scan-build --use-analyzer=/Users/tester/workspace/WeixinTest/clang/release3.2/build/Release+Asserts/bin/clang -o ~/Documents -enable-checker test.NewChecker xcodebuild -workspace /Users/tester/workspace/WeixinTest/workspace/PropMemFun/PropMemFun.xcodeproj/project.xcworkspace -scheme PropMemFun -sdk iphoneos6.1 build
not work
it seems that -enable-checker does not work because $Options->{“CCC_ANALYZER_ANALYSIS”} is not used .the code:

my $OutputDir = $Options->{“OUTPUT_DIR”};
my $CLANG = $Options->{“CLANG”};
push @$Args,
“RUN_CLANG_STATIC_ANALYZER=YES”,
“CLANG_ANALYZER_OUTPUT=plist-html”,
“CLANG_ANALYZER_EXEC=$CLANG”,
“CLANG_ANALYZER_OUTPUT_DIR=$OutputDir”;
return (system(@$Args) >> 8);

my question is :how can I enable alpha/debug checker or my own checker
