给 iOS 模拟器“安装” app 文件

前言

刚刚接触iOS的时候,我就一直很好奇,模拟器上面能不能直接安装app呢?如果可以,我们就直接在模拟器上面聊QQ和微信了。直到昨天和朋友们聊到了这个话题,没有想到还真的可以给模拟器“安装”app!

一.应用场景

先来谈谈是什么情况下,会有在模拟器上安装app的需求。

在一个大公司里,对源码的管理有严格的制度,非开发人员是没有权限接触到源码的。对苹果的开发证书管理也非常严格,甚至连开发人员也没有发布证书,证书只在持续集成环境或者Appstore产线里面,或者只在最后打包上架的人手上。

那么现在就有这样的需求,开发人员搭建好UI以后,要把开发完成的Alapha版给到UI设计师那边去评审,看看是否完全达到要求,达不到要求就需要打回来重做。

一般做法就是直接拿手机去安装一遍了。直接真机看效果。不过要是设计师和开发不在同一个地方的公司,一个在北京一个在上海,这种就没法安装了。源码又无法导出给设计师,让他运行一下Xcode跑一下模拟器。这个时候就比较麻烦了。(一般也没人遇到这么蛋疼的事情吧)

那么现在就有给模拟器安装app的需求了,那开发人员如何能把开发版的app给打包出来给其他模拟器安装呢?

二.解决办法

解决思路,想要别人的模拟器运行起我们开发的app,最简单的办法就是把我们DerivedData的数据直接拷贝到别人模拟器上面,就可以了。当然还要考虑到设计师也许并不会一些命令行命令,我们的操作越傻瓜越好。

1.拷贝本地的DerivedData里面的debug包

Mac的拷贝命令有cp和ditto,建议用ditto进行拷贝工作。


Usage: ditto [ <options> ] src [ ... src ] dst

    <options> are any of:
    -h                         print full usage
    -v                         print a line of status for each source copied
    -V                         print a line of status for every file copied
    -X                         do not descend into directories with a different device ID

    -c                         create an archive at dst (by default CPIO format)
    -x                         src(s) are archives
    -z                         gzip compress CPIO archive
    -j                         bzip2 compress CPIO archive
    -k                         archives are PKZip
    --keepParent               parent directory name src is embedded in dst_archive
    --arch archVal             fat files will be thinned to archVal
                               multiple -arch options can be specified
                               archVal should be one of "ppc", "i386", etc
    --bom bomFile              only objects present in bomFile are copied
    --norsrc                   don't preserve resource data
    --noextattr                don't preserve extended attributes
    --noqtn                    don't preserve quarantine information
    --noacl                    don't preserve ACLs
    --sequesterRsrc            copy resources via polite directory (PKZip only)
    --nocache                  don't use filesystem cache for reads/writes
    --hfsCompression           compress files at destination if appropriate
    --nopreserveHFSCompression don't preserve HFS+ compression when copying files
    --zlibCompressionLevel num use compression level 'num' when creating a PKZip archive
    --password                 request password for reading from encrypted PKZip archive

Ditto比cp命令更好的地方在于:

  1. 它在复制过程中不仅能保留源文件或者文件夹的属性与权限,还能保留源文件的资源分支结构和文件夹的源结构。
  2. 此命令能确保文件或者文件夹被如实复制。
  3. 如果目标文件或者文件夹不存在,ditto将直接复制过去或创建新的文件和文件夹,相反,对于已经存在的文件,命令将与目标文件(夹)合并。
  4. ditto还能提供完整符号链接。

那么我们就拷贝出本地的debug包

ditto -ck --sequesterRsrc --keepParent `ls -1 -d -t ~/Library/Developer/Xcode/DerivedData/*/Build/Products/*-iphonesimulator/*.app | head -n 1` /Users/YDZ/Desktop/app.zip

有几点需要说明的:

  1. 上面命令最后一个路径(/Users/YDZ/Desktop/app.zip),这个是自定义的,我这里举的例子是直接放在桌面。除了这里改一下路径,前面的都不需要改,包括 * 也都不用改。

  2. 再来说一下命令里面的 * 的问题。当我们打开自己本地的~/Library/Developer/Xcode/DerivedData/ ,这个路径下,会发现里面装的都是在我们本地模拟器上运行过的app程序。前面是app的Bundle Identifier,横线后面是一堆字符串。上面的ditto里面带 * 的那个路径是为了动态匹配一个地址的,* 在这里也是一个通配符。后面的head说明了匹配的规则。head其实是找出最近一次我们运行模拟器的app的路径。

为了保证我们打包是正确的,建议先运行一下我们要打包的app,一般我们Scheme里面的Run都是debug product(如果这里有更改,那就改成对应debug的Scheme),确保是我们要给设计师审核的app,之后再运行这个ditto命令。

2.把debug包拷贝到另一个模拟器中

我们运行完上面的ditto命令会产生一个zip文件,解压出来,会得到一个app文件,这个就是debug包了。debug包就是我们要给设计师的app包了。

如何能让设计师傻瓜式的安装这个app呢?

这里介绍一个命令行工具,ios-sim命令行工具。

ios-sim 是一个可以在命令控制iOS模拟器的工具。利用这个命令,我们可以启动一个模拟器,安装app,启动app,查询iOS SDK。它可以使我们像自动化测试一样不用打开Xcode。

不过 ios-sim 只支持Xcode 6 以后的版本。

安装ios-sim

    $ npm install ios-sim -g

说明文档:


    Usage: ios-sim <command> <options> [--args ...]
        
    Commands:
      showsdks                        List the available iOS SDK versions
      showdevicetypes                 List the available device types
      launch <application path>       Launch the application at the specified path on the iOS Simulator
      start                           Launch iOS Simulator without an app
      install <application path>      Install the application at the specified path on the iOS Simulator without launching the app

    Options:
      --version                       Print the version of ios-sim
      --help                          Show this help text
      --exit                          Exit after startup
      --log <log file path>           The path where log of the app running in the Simulator will be redirected to
      --devicetypeid <device type>    The id of the device type that should be simulated (Xcode6+). Use 'showdevicetypes' to list devices.
                                      e.g "com.apple.CoreSimulator.SimDeviceType.Resizable-iPhone6, 8.0"
                                  
    Removed in version 4.x:
      --stdout <stdout file path>     The path where stdout of the simulator will be redirected to (defaults to stdout of ios-sim)
      --stderr <stderr file path>     The path where stderr of the simulator will be redirected to (defaults to stderr of ios-sim)
      --sdk <sdkversion>              The iOS SDK version to run the application on (defaults to the latest)
      --family <device family>        The device type that should be simulated (defaults to `iphone')
      --retina                        Start a retina device
      --tall                          In combination with --retina flag, start the tall version of the retina device (e.g. iPhone 5 (4-inch))
      --64bit                         In combination with --retina flag and the --tall flag, start the 64bit version of the tall retina device (e.g. iPhone 5S (4-inch 64bit))
                                    
    Unimplemented in this version:
      --verbose                       Set the output level to verbose
      --timeout <seconds>             The timeout time to wait for a response from the Simulator. Default value: 30 seconds
      --args <...>                    All following arguments will be passed on to the application
      --env <environment file path>   A plist file containing environment key-value pairs that should be set
      --setenv NAME=VALUE             Set an environment variable
                                  

用法不难

ios-sim launch /Users/YDZ/Desktop/app.app --devicetypeid iPhone-6s 

其中,/Users/YDZ/Desktop/app.app这个是设计师收到app之后的路径。--devicetypeid参数后面是给定一个模拟器的版本。

只需要把上面的命令发给设计师,无脑粘贴到命令行,装好app的模拟器就会自动启动,打开app了。

三.额外的尝试

好奇的同学肯定不会满足只给模拟器安装debug包吧,既然可以不用代码就可以给模拟器安装app,那我们能安装release包么?我好奇的尝试了一下。

先从Appstore上面下载最新的微信,把ipa后缀改成zip,解压,把Payload文件夹里面的“WeChat”取出来,然后运行ios-sim命令。

结果微信确实是安装到了模拟器了。不过一点击app,看见了月亮界面就退出了。控制台打印了一堆信息。

仔细看了一下log,根本原因还是因为

com.apple.CoreSimulator.SimDevice.D6BD3967-9BC4-4A8D-9AD0-23176B22B12A.launchd_sim[19096] (UIKitApplication:com.tencent.xin[0xdf6d][19774]): Program specified by service does not contain one of the requested architectures:

Unable to get pid for 'UIKitApplication:com.tencent.xin[0xdf6d]': No such process (err 3)

因为release包里面architectures打包的时候不包含模拟器的architectures。debug包里面就有。所以release就没法安装到模拟器了。

由于笔者逆向方面的东西没有研究,所以也无法继续下去了。不知道逆向技术能不能把release包破壳之后能不能转成debug包呢?如果能转成debug包,通过ios-sim命令应该也是可以直接安装到模拟器的。

至此,ios-sim给模拟器安装app就尝试到此了。因为只能给模拟器安装debug包,所以在题目上额外给安装加了双引号,并不是所有的app文件都可以安装到模拟器。

请大家多多指教。
