iPhone开发进阶（4） --- 使用Makefile自动编译iPhone程序

Xcode 也支持以命令行形式来编译 iPhone 程序。另外还可以手动的编写 Makefile 文件，实现编译→安装的自动化批处理过程。如果你习惯了命令行的操作方式（linux,unix），那么这样的操作还是很方便的。

首先看看 Xcode 的命令行格式：

 

xcodebuild -target Project_Name
xcodebuild install -target Project_Name

下面我们来实现程序的编译，并通过 ldid 转换编码格式，最后用 ssh 将编译好的程序安装到 iPhone 上的 /Applications/目录下。

首先安装 ssh 的公开密匙到 iPhone 上

1). 在Mac的终端上产生密匙

ssh-keygen -t rsaGenerating public/private rsa key pair.Enter file in which to save the key (/home/xxxx/.ssh/id_rsa):Created directory '/home/xxxx/.ssh'.Enter passphrase (empty for no passphrase): xxxEnter same passphrase again: xxxYour identification has been saved in /home/xxxx/.ssh/id_rsa.Your public key has been saved in /home/xxxx/.ssh/id_rsa.pub.The key fingerprint is:e4:e8:b7:05:06:b3:f0:ff:af:13:fc:50:6a:5b:d1:b5 xxxx@localhost.localdomain

过程中会提问你通行证（passphrase），输入你常用的秘密。

2). 在 iPhone 上创建.ssh目录（iPhone的IP地址是10.0.2.2）

ssh root@10.0.2.2 'mkdir -p .ssh'

如果问道你iPhone root password，输入 alpine。

3). 拷贝刚才生成的公开密匙到 iPhone

cat ~/.ssh/id_rsa.pub | ssh root@10.0.2.2 'cat >> .ssh/authorized_keys'

如果问道你iPhone root password，输入 alpine。

4). 在 iPhone 上编辑 /etc/ssh/sshd_config 文件

#将
#StrictModes yes
#PubkeyAuthentication yes
#AuthorizedKeysFile .ssh/authorized_keys

#替换为

StrictModes no
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys

5). 重新启动iPhone

接下来，编译生成ldid工具

wget http://svn.telesphoreo.org/trunk/data/ldid/ldid-1.0.610.tgz

tar -zxf ldid-1.0.610.tgz

# 如果是 PowerPC 下载下面的补丁
# wget -qO- http://fink.cvs.sourceforge.net/viewvc/*checkout*/fink/dists/10.4/unstable/crypto/finkinfo/ldid.patch?revision=1.1 | patch -p0

cd ldid-1.0.610

g++ -I . -o util/ldid{,.cpp} -x c util/{lookup2,sha1}.c

sudo cp -a util/ldid /usr/bin

最后，让我们看看Makefile中都有什么

项目中的文件如下所示：

Classes : source code (.m .c .cpp etc)Resources : png file and other support filesProject folder : *.xib Info.plist

 

Makefile: Select all
