iphone - Xcode 目标阶段 Python 脚本

Question

我正在尝试将 Python 脚本添加到我的项目中，以直接从 Git 获取内部版本号和营销号。

我已经创建了一个新的目标阶段并运行了一个脚本，如下所述:

我写了一个 Python 脚本来解析程序 Info.plist 使用

from Foundation import NSMutableDictionary

但是脚本在编译时失败并向构建结果报告以下错误:

Running a custom build phase script: gitversion.py  
Traceback (most recent call last):

distutils.errors.DistutilsPlatformError: $MACOSX_DEPLOYMENT_TARGET mismatch: now "10.5" but "10.6" during configure  
Finished running custom build phase script: gitversion.py (exit status = 1)

显然，distutils 以某种方式硬编码它是为 10.6 版(Snow Leopard，我正在使用的版本)编译的，但该项目的 MacOSX 部署目标设置为 10.5。

如果我尝试将项目中的这个变量设置为 10.6，我会得到:

ld: library not found for -lcrt1.10.6.o

关于如何解决这个问题有什么想法吗？提前致谢。

我有同样的问题，我想保留 python 版本，因为通过 NSMutableDictionary 处理 plist比在 Info.plist 上使用正则表达式要好得多.

基于 Maxence 的回答，解决方案是将 Python 代码从运行脚本构建阶段剥离到 gitversion.py 中。文件:

#!/usr/bin/env python
import os
from Foundation import NSMutableDictionary
from subprocess import Popen, PIPE

p = Popen(
        "/sw/bin/git rev-parse --short HEAD", 
        stdout=PIPE, 
        close_fds=True,
        shell=True)

version = p.stdout.read()
print version
info = os.environ['INFOPLIST_FILE']
print info
plist = NSMutableDictionary.dictionaryWithContentsOfFile_(info)
print plist
plist['revision'] = version[:-1]
plist.writeToFile_atomically_(info, 1)

然后用shell脚本替换原来的Run Script:

env MACOSX_DEPLOYMENT_TARGET=10.6 python gitversion.py

一定要记得改Shell设置为 /bin/sh .
