foreword
When I first came into contact with iOS, I have always been curious, can the app be installed directly on the simulator? If possible, we will chat QQ and WeChat directly on the simulator. Until yesterday, I talked about this topic with my friends, I didn't think that I could really "install" the app for the simulator!
1. Application scenarios
Let's talk about the situation first, there will be a need to install the app on the simulator.
In a large company, there is a strict system for the management of source code, and non-developers do not have permission to access the source code. Apple's development certificate management is also very strict. Even developers have not issued certificates. The certificates are only in the continuous integration environment or the Appstore production line, or only in the hands of the people who finally packaged and put them on the shelves.
Then there is such a demand now. After the developers build the UI, they should send the developed Alapha version to the UI designer for review to see if they fully meet the requirements. If they do not meet the requirements, they need to call back and redo them.
The general practice is to take the phone directly to install it again. See the effect directly on the real machine. However, if the designers and developers are not in the same place, one is in Beijing and the other is in Shanghai, this kind of installation is impossible. The source code cannot be exported to the designer, let him run Xcode and run the simulator. The release ipa is installed by scanning the code. If the company is large, all the UDIDs are used up, and it cannot be installed. This time it is more troublesome. (No one has ever encountered such a painful thing.)
So now there is a need to install apps for simulators, so how can developers package the development version of the app for other simulators to install?
2. Solutions
The solution is to copy the data of our DerivedData directly to other people's simulators to run the app we developed on other people's simulators. Of course, we must also consider that the designer may not know some command line commands. The more foolish we are, the better.
1. Copy the debug package in the local DerivedData
Mac's copy commands include cp and ditto. It is recommended to use ditto for copy work.
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 archiveWhere Ditto is better than the cp command is:
- It can not only preserve the attributes and permissions of the source file or folder during the copying process, but also preserve the resource branch structure of the source file and the source structure of the folder.
- This command ensures that the file or folder is copied faithfully.
- If the target file or folder does not exist, ditto will copy it directly or create a new file and folder, on the contrary, for existing files, the command will merge with the target file (folder).
- ditto also provides full symbolic links.
Then we copy the local debug package
ditto -ck --sequesterRsrc --keepParent `ls -1 -d -t ~/Library/Developer/Xcode/DerivedData/*/Build/Products/*-iphonesimulator/*.app | head -n 1` /Users/YDZ/Desktop/app.zipA few things to note:
-
The last path (/Users/YDZ/Desktop/app.zip) of the above command is customized. The example I gave here is directly on the desktop. Except for changing the path here, none of the previous ones need to be changed, including *.
-
Let's talk about the * in the command. When we open our local ~/Library/Developer/Xcode/DerivedData/ , under this path, we will find that all the apps that have been run on our local simulator are installed. The front is the app's Bundle Identifier, and the horizontal line is followed by a bunch of strings. The path with * in the ditto above is to dynamically match an address, and * is also a wildcard here. The following head describes the matching rules. head actually finds the path to the app where we last ran the emulator.
In order to ensure that our packaging is correct, it is recommended to run the app we want to package first. Generally, the Run in our Scheme is the debug product (if there is a change here, then change it to the Scheme corresponding to debug), to ensure that we want to design the design The app reviewed by the teacher, and then run the ditto command.
2. Copy the debug package to another simulator
After we run the above ditto command, a zip file will be generated, unzip it, and we will get an app file, which is the debug package. The debug package is the app package we want to give to designers.
How to get designers to install this app foolishly?
Here is a command line tool, the ios-sim command line tool.
ios-sim is a tool that can control the iOS simulator at the command. With this command, we can start an emulator, install the app, launch the app, and query the iOS SDK. It allows us to automate testing without opening Xcode.
However, ios-sim only supports Xcode 6 and later versions.
install ios-sim
$ npm install ios-sim -gDocumentation:
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 variableEasy to use
ios-sim launch /Users/YDZ/Desktop/app.app --devicetypeid iPhone-6sAmong them, /Users/YDZ/Desktop/app.app is the path after the designer receives the app. The --devicetypeid parameter is followed by the version of a given emulator.
Just send the above command to the designer, paste it into the command line without thinking, the simulator with the app installed will automatically start, and the app will be opened.
3. Additional attempts
Curious students will definitely not be satisfied with only installing the debug package for the simulator. Since we can install the app on the simulator without code, can we install the release package? I tried it out of curiosity.
First download the latest WeChat from the Appstore, change the ipa suffix to zip, unzip it, take out "WeChat" in the Payload folder, and then run the ios-sim command.
As a result, WeChat is indeed installed in the simulator. But as soon as you click on the app, you will exit when you see the moon interface. The console prints a bunch of information.
An error was encountered processing the command (domain=FBSOpenApplicationErrorDomain, code=1):
The operation couldn’t be completed. (FBSOpenApplicationErrorDomain error 1.)

Since the author has not studied the reverse aspect, I cannot continue. I wonder if the reverse technology can convert the release package into a debug package after breaking the shell? If it can be converted into a debug package, it should also be directly installed to the simulator through the ios-sim command.
So far, ios-sim has tried to install the app on the simulator. Because only the debug package can be installed for the simulator, double quotes are added to the installation, and not all app files can be installed on the simulator.
Please exhibitions.
