|
|
|
This toolchain is designed to compile the necessary libraries for iOS to run
|
|
your application and manage the creation of the Xcode project.
|
|
|
|
We do not provide any binary distributions of this toolchain.
|
|
You do need to compile it at least once before creating your Xcode project.
|
|
|
|
The toolchain supports:
|
|
|
|
- iPhone Simulator (x86_64)
|
|
- iPhone / iOS (armv7 and arm64)
|
|
|
|
These recipes are not ported to the new toolchain yet:
|
|
|
|
- lxml
|
|
|
|
|
|
## Installation & requirements
|
|
|
|
Before we start, we strongly advise to use a Python virtual environment to install Python packages.
|
|
|
|
python3 -m venv venv
|
|
. venv/bin/activate
|
|
|
|
Install [Kivy for iOS from PyPI](https://pypi.org/project/kivy-ios) with pip like any Python package.
|
|
|
|
pip3 install kivy-ios
|
|
|
|
Additionally you would need few system dependencies and configuration.
|
|
|
|
- Xcode 10 or above, with an iOS SDK and command line tools installed:
|
|
|
|
xcode-select --install
|
|
|
|
- Using brew, you can install the following dependencies:
|
|
|
|
brew install autoconf automake libtool pkg-config
|
|
brew link libtool
|
|
|
|
## Using the toolchain
|
|
|
|
Any Python extensions or C/C++ library must be compiled: you need to have what
|
|
we call a `recipe` to compile it. For example, Python, libffi, SDL2, SDL_image,
|
|
freetype... all the dependencies, compilation and packaging instructions are
|
|
contained in a `recipe`.
|
|
|
|
You can list the available recipes and their versions with:
|
|
|
|
$ toolchain recipes
|
|
audiostream master
|
|
click 7.1.2
|
|
cymunk master
|
|
ffmpeg 2.6.3
|
|
ffpyplayer v3.2
|
|
flask 1.1.2
|
|
freetype 2.5.5
|
|
hostlibffi 3.2.1
|
|
hostpython3 3.7.1
|
|
ios master
|
|
itsdangerous 1.1.0
|
|
jinja2 2.11.2
|
|
kivy 1.10.1
|
|
libffi 3.2.1
|
|
libjpeg v9a
|
|
libpng 1.6.26
|
|
markupsafe 1.1.1
|
|
moodstocks 4.1.5
|
|
numpy 1.16.4
|
|
openssl 1.0.2k
|
|
photolibrary master
|
|
pillow 6.1.0
|
|
plyer master
|
|
pycrypto 2.6.1
|
|
pykka 1.2.1
|
|
pyobjus master
|
|
python3 3.7.1
|
|
pyyaml 3.11
|
|
sdl2 2.0.8
|
|
sdl2_image 2.0.0
|
|
sdl2_mixer 2.0.0
|
|
sdl2_ttf 2.0.12
|
|
werkzeug 1.0.1
|
|
|
|
Then, start the compilation with:
|
|
|
|
$ toolchain build python3 kivy
|
|
|
|
You can build recipes at the same time by adding them as parameters:
|
|
|
|
$ toolchain build python3 openssl kivy
|
|
|
|
Recipe builds can be removed via the clean command e.g.:
|
|
|
|
$ toolchain clean openssl
|
|
|
|
You can install package that don't require compilation with pip::
|
|
|
|
$ toolchain pip install plyer
|
|
|
|
The Kivy recipe depends on several others, like the sdl\* and python recipes.
|
|
These may in turn depend on others e.g. sdl2_ttf depends on freetype, etc.
|
|
You can think of it as follows: the kivy recipe will compile everything
|
|
necessary for a minimal working version of Kivy.
|
|
|
|
Don't grab a coffee, just do diner. Compiling all the libraries for the first
|
|
time, 3x over (remember, 3 archs, x86_64, armv7, arm64) will take time.
|
|
|
|
For a complete list of available commands, type:
|
|
|
|
$ toolchain
|
|
|
|
## Create the Xcode project
|
|
|
|
The `toolchain.py` can create the initial Xcode project for you::
|
|
|
|
$ toolchain create <title> <app_directory>
|
|
$ toolchain create Touchtracer ~/code/kivy/examples/demo/touchtracer
|
|
|
|
Your app directory must contain a main.py. A directory named `<title>-ios`
|
|
will be created, with an Xcode project in it.
|
|
You can open the Xcode project using::
|
|
|
|
$ open touchtracer-ios/touchtracer.xcodeproj
|
|
|
|
Then click on `Play`, and enjoy.
|
|
|
|
> *Did you know ?*
|
|
>
|
|
> Everytime you press `Play`, your application directory will be synced to
|
|
> the `<title>-ios/YourApp` directory. Don't make changes in the -ios
|
|
> directory directly.
|
|
|
|
|
|
## Configuring your App
|
|
|
|
You can configure and customize your app in various ways:
|
|
|
|
- Set the icon and launch images in XCode. Note that XCode requires that you
|
|
specify these assests per device or/and iOS version.
|
|
|
|
- When you first build your XCode project, a 'main.m' file is created in your
|
|
XCode project folder. This file configures your environment variables and
|
|
controls your application startup. You can edit this file to customize your
|
|
launch environment.
|
|
|
|
- Kivy uses SDL, and as soon as the application starts the SDL main, the launch
|
|
image will disappear. To prevent that, you need to have 2 files named
|
|
`Default.png` and `Default-Landscape.png`, and put them
|
|
in the `Resources` folder in Xcode (not in your application folder)
|
|
|
|
> *Did you know ?*
|
|
>
|
|
> If you wish to restrict your apps orientation, you should do this via
|
|
> the 'export_orientation' function in 'main.m'. The XCode orientation
|
|
> settings should be set to support all.
|
|
|
|
|
|
## Using recipes
|
|
|
|
Recipes are used to install and compile any libraries you may need to use. These
|
|
recipes follow the same format as those used by the
|
|
[Python-for-Android](https://github.com/kivy/python-for-android) sister project.
|
|
Please refer to the
|
|
[recipe documentation](https://python-for-android.readthedocs.io/en/latest/recipes/)
|
|
there for more detail.
|
|
|
|
|
|
## Reducing the application size
|
|
|
|
If you would like to reduce the size of your distributed app, there are a few
|
|
things you can do to achieve this:
|
|
|
|
- Minimize the `build/pythonX/lib/pythonXX.zip`: this contains all the python
|
|
modules. You can edit the zip file and remove all the files you'll not use
|
|
(reduce encodings, remove xml, email...)
|
|
|
|
- Go to the settings `panel` > `build`, search for `"strip"` options, and
|
|
triple-check that they are all set to `NO`. Stripping does not work with
|
|
Python dynamic modules and will remove needed symbols.
|
|
|
|
- By default, the iOS package compiles binaries for all processor
|
|
architectures, namely x86_64, armv7 and arm64 as per the guidelines from
|
|
Apple. You can reduce the size of your ipa significantly by removing the
|
|
x86_64 architecture as they are used only for the emulator.
|
|
|
|
The procedure is to first compile/build all the host recipes as is:
|
|
|
|
toolchain build hostpython3
|
|
|
|
Then build all the rest of the recipes using --arch=armv7 --arch=arm64
|
|
arguments as follows:
|
|
|
|
toolchain build python3 kivy --arch=armv7 --arch=arm64
|
|
|
|
Note that these packages will not run in the iOS emulators, so use them
|
|
only for deployment.
|
|
|
|
## Usage
|
|
|
|
```
|
|
toolchain <command> [<args>]

|
|
architecture)
|
|
clean Clean the build of the specified recipe
|
|
distclean Clean the build and the result
|
|
recipes List all the available recipes
|
|
status List all the recipes and their build status
|
|
|
|
Xcode:

|
|
update Update an existing xcode project (frameworks, libraries..)
|
|
launchimage Create Launch images for your xcode project
|
|
icon Create Icons for your xcode project
|
|
pip Install a pip dependency into the distribution
|
|

|
|
```
|
|
|
|
## Development
|
|
|
|
Alternatively, it's also possible to clone the repository and use all the
|
|
described commands in the above sections.
|
|
Clone and install it to your local virtual environment:
|
|
|
|
git clone https://github.com/kivy/kivy-ios.git
|
|
cd kivy-ios/
|
|
python3 -m venv venv
|
|
. venv/bin/activate
|
|
pip install -e .
|
|
|
|
Then use the `toolchain.py` script:
|
|
|
|
python toolchain.py --help
|
|
|
|
|
|
## FAQ
|
|
|
|
### Fatal error: "stdio.h" file not found
|
|
|
|
You need to install the Command line tools: `xcode-select --install`
|
|
|
|
### You must build with bitcode disabled (Xcode setting ENABLE_BITCODE should be No).
|
|
|
|
We don't support bitcode. You need to go to the project setting, and disable bitcode.
|
|
|
|
### You don't have permissions to run
|
|
|
|
It is due to invalid archs, search for them and check it. Maybe you
|
|
targetted a simulator but have only armv7/arm64. Maybe you want to target
|
|
your iPad but it as only x86_64.
|
|
|
|
### Why does the python multiprocess/subprocess module not work?
|
|
|
|
The iOS application model does not currently support multi-processing in a
|
|
cross-platform compatible way. The application design focuses on minimizing
|
|
processor usage (to minimize power consumption) and promotes an
|
|
[alternative concurrency model](https://developer.apple.com/library/archive/documentation/General/Conceptual/ConcurrencyProgrammingGuide/Introduction/Introduction.html).
|
|
|
|
If you need to make use of multiple processes, you should consider using
|
|
[PyObjus](https://github.com/kivy/pyobjus) to leverage native iOS
|
|
functionals for this.
