生成ipa 这个是自己总结的，ios5.1.1越狱系统，xcode4.3.3可用

最有用的一段

export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
if [ "${PLATFORM_NAME}" == "iphoneos" ] || [ "${PLATFORM_NAME}" == "ipados" ]; then
/Applications/Xcode.app/Contents/Developer/iphoneentitlements/gen_entitlements.py "my.company.${PROJECT_NAME}" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent";
codesign -f -s "haohao" --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
fi

1.建立 “钥匙串”
如图，比如家里钥匙串为 “haohao”
创建证书

后面默认

2.xcode选择设备，插入设备
右上角，Organizer
选择设备，并开发者模式

3.在 中间的设置
build setting 中的
code signing Identiy
中andy ios sdk 设置为 “haohao”

4.在build Phase 中的右下角
Add build Phase
使用Add run shell
如图，shell内容如下 注意这里的“haohao” 为刚才生成的钥匙串的名字
其他的都不变，什么“my.company.”之类的都不变

export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
if [ "${PLATFORM_NAME}" == "iphoneos" ] || [ "${PLATFORM_NAME}" == "ipados" ]; then
/Applications/Xcode.app/Contents/Developer/iphoneentitlements/gen_entitlements.py "my.company.${PROJECT_NAME}" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent";
codesign -f -s "haohao" --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
fi

以上内容注意
中需要用到一个python文件生成.xcent文件到app中，

apple:test1.app apple$ cat /Applications/Xcode.app/Contents/Developer/iphoneentitlements/gen_entitlements.py
#!/usr/bin/env python

import sys
import struct

if len(sys.argv) != 3:
	print "Usage: %s appname dest_file.xcent" % sys.argv[0]
	sys.exit(-1)

APPNAME = sys.argv[1]
DEST = sys.argv[2]

if not DEST.endswith('.xml') and not DEST.endswith('.xcent'):
	print "Dest must be .xml (for ldid) or .xcent (for codesign)"
	sys.exit(-1)

entitlements = """
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

    <key>application-identifier</key>
    <string>%s</string>
    <key>get-task-allow</key>
    <true/>
</dict>
</plist>
""" % APPNAME

f = open(DEST,'w')
if DEST.endswith('.xcent'):
	f.write("\xfa\xde\x71\x71")
	f.write(struct.pack('>L', len(entitlements) + 8))
f.write(entitlements)
f.close()

apple:test1.app apple$ 

－－－－－－－－－－－－
还要设置一下一些，一下这些是借鉴别人的文章

apple:Desktop apple$ cat xcode.txt 
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk

sudo cp SDKSettings.plist SDKSettings.plist.orig
进行编辑
sudo vim SDKSettings.plist
将以下两段中的YES改为NO
<key>CODE_SIGNING_REQUIRED</key>
<string>YES</string>
和
<key>ENTITLEMENTS_REQUIRED</key>
<string>YES</string>

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform
sudo cp Info.plist Info.plist.orig
sudo vim Info.plist
将全部的XCiPhoneOSCodeSignContext 修改成 XCCodeSignContext，3处

mkdir /Applications/Xcode.app/Contents/Developer/iphoneentitlements
cd /Applications/Xcode.app/Contents/Developer/iphoneentitlements
curl -O http://www.alexwhittemore.com/iphone/gen_entitlements.txt
mv gen_entitlements.txt gen_entitlements.py

	sys.exit(-1)

APPNAME = sys.argv[1]
DEST = sys.argv[2]

if not DEST.endswith('.xml') and not DEST.endswith('.xcent'):
	print "Dest must be .xml (for ldid) or .xcent (for codesign)"
	sys.exit(-1)

看图 把xcode的工程的所有的code sign去掉

----------
export CODESIGN_ALLOCATE=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate
if [ "${PLATFORM_NAME}" == "iphoneos" ] || [ "${PLATFORM_NAME}" == "ipados" ]; then
/Applications/Xcode.app/Contents/Developer/iphoneentitlements/gen_entitlements.py "my.company.${PROJECT_NAME}" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent";
codesign -f -s "haohao" --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
fi

[color=darkred]到
/Users/apple/Library/Developer/Xcode/DerivedData/test1-gmkvwytfnpktwcfdsyetryfgpitk/Build/Products/Debug-iphoneos
目录下找到 test1.app拖拽到itunes,再拖拽出来就变成ipa了，用91或者itunes或者nginx把ipa文件传到iphone上就可以了[/color]

5.生成ipa
到
