Xcode假设不破解。无法真机调试, 也无法编译真机Release文件。仅仅有付费开通Apple开发人员账号，才干申请真机调试。而Xcode进行破解后，结合越狱的iPhone或iPad, 就可以免官方证书开发调试了！

生成本机证书

应用程序->其它->钥匙串訪问

菜单：钥匙串訪问->证书助理->创建证书, 然后按下面图片顺序操作就可以：

Xcode 5免证书开发调试_打开创建证书菜单

Xcode 5免证书开发调试_输入证书名称iPhone Developer并选择覆盖默认值

Xcode 5免证书开发调试_确定继续

Xcode 5免证书开发调试_输入序列号有效期，有效期不要超过365天

Xcode 5免证书开发调试_输入电子邮件地址

Xcode 5免证书开发调试_输入密钥对信息

Xcode 5免证书开发调试_密钥使用扩展扩展选择：签名

Xcode 5免证书开发调试_已扩展的密钥使用扩展选择：代码签名

Xcode 5免证书开发调试_基本约束扩展不选择

Xcode 5免证书开发调试_主题备用名称扩展输入RFC822名称，填入邮箱名就可以

Xcode 5免证书开发调试_用于该证书的位置选择钥匙串类型为登录

Xcode破解

保证Xcode处于关闭状态，命令行终端，复制粘贴以下的代码：

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/PrivatePlugIns/iPhoneOS\ Build\ System\ Support.xcplugin/Contents/MacOS/
sudo dd if=iPhoneOS\ Build\ System\ Support of=~/working bs=500 count=255
sudo chown mac<span style="font-family: Consolas, ‘Bitstream Vera Sans Mono‘, ‘Courier New‘, Courier, monospace; font-size: 13px; line-height: 26px; background-color: rgb(248, 248, 248);">(你登陆系统的username,我的username是mac)</span>:staff ~/working
printf "\x8f\x2a\x00\x00" >> ~/working
dd if=iPhoneOS\ Build\ System\ Support of=~/working bs=1 skip=127504 seek=127504
sudo /bin/mv -n iPhoneOS\ Build\ System\ Support iPhoneOS\ Build\ System\ Support.original
sudo /bin/mv ~/working iPhoneOS\ Build\ System\ Support
sudo chmod a+x iPhoneOS\ Build\ System\ Support
sudo chown root:wheel iPhoneOS\ Build\ System\ Support

Xcode5免证书真机调试-改动SDKSettings.plist

改动保存后再将文件移回原处:

sudo mv ~/SDKSettings.plist /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/
sudo chown root:wheel /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk/SDKSettings.plist

sudo mv /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Info.plist ~/ #文件移动到用户文件夹
sudo chown mac(你登陆系统的username,我的username是mac):staff ~/Info.plist

PROVISIONING_PROFILE_ALLOWED = NO
PROVISIONING_PROFILE_REQUIRED = NO

Xcode5免证书真机调试-改动Info.plist

然后将该文件里全部的"XCiPhoneOSCodeSignContext"替换为"XCCodeSignContext"，即去掉中间的"iPhoneOS" 。

假设不进行此步。编译Device Release版本号时會报错：

Code Sign error: a valid provisioning profile matching the application‘s Identifier ‘com.yourcompany.xxxx‘ could not be found

Xcode5免证书真机调试-改动Info.plist替换标识

sudo mv ~/Info.plist /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/ #文件移回原处
sudo chown root:wheel /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Info.plist

改动项目属性 （每次新建项目都要运行）

A. 点击项目图标，找到"BuildSettings"选项下的"Code Sign Identity"，将其值所有改为"Don‘t Code Sign"

B. 切换到Build Phases选项，点击菜单Editor->Add Build Phase->Add Run Script Build Phase，然后单击Add Run Script，然后在Run Script中输入下面脚本：

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 "iPhone Developer" --entitlements "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/${PROJECT_NAME}.xcent" "${BUILT_PRODUCTS_DIR}/${WRAPPER_NAME}/"
fi

Xcode5免证书真机调试-写入脚本

Xcode破解完毕，或者更准确的讲，是配置完毕！

Xcode真机调试

将 iPhone接入电脑，在Xcode的Window->Organizer中会检測到你的iPhone.点击 restore using developer

查看iPhone和你的Xcode识别正常后退出Organizer。选择编译环境为"iPhone Device-我有一个姑娘我非常爱她",点击"Build and Go"

期间会出现让我们选择签名证书，点选"同意"后。等待你的iPad/iPhone屏幕点亮就ok了。

你的程序会自己主动下载到你的iPhone中，能够进行真机调试了

Xcode升级破解

假设是在原Xcode的版本号上升级到5，而且之前已经破解过。那么仅仅须要再做例如以下步骤就可以：

在/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Info.plist中新增例如以下两项(告知项目编译无需证书)：

PROVISIONING_PROFILE_ALLOWED = NO
PROVISIONING_PROFILE_REQUIRED = NO

Code Sign error: a valid provisioning profile matching the application‘s Identifier ‘com.yourcompany.xxxx‘ could not be found
