# iOS / OSX example
|
|
|
|
## Introduction
|
|
|
|
This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/) to share mouse/keyboard on an iOS device.
|
|
|
|
It is a rather complex and messy example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui. **The opengl3_example/ should also work on OS X and is much simpler.** This is an integration for iOS with Synergy.
|
|
|
|
Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
|
|
|
|
## How to Use on iOS
|
|
|
|
* In Synergy, go to Preferences, and uncheck "Use SSL encryption"
|
|
* Run the example app.
|
|
* Tap the "servername" button in the corner
|
|
* Enter the name or the IP of your synergy host
|
|
* If you had previously connected to a server, you may need to kill and re-start the app.
|
|
|
|
## How to Build on OSX
|
|
|
|
* Make sure you have install `brew`, if not, please refer to [Homebrew Website](http://brew.sh)
|
|
* Run the command: `brew install glfw3`
|
|
* Double click `imguiex.xcodeproj` and select `imguiex-osx` scheme
|
|
* Click `Run` button
|
|
|
|
## Notes and TODOs
|
|
|
|
Things that would be nice but I didn't get around to doing:
|
|
|
|
* iOS software keyboard not supported for text inputs
|
|
* iOS hardware (bluetooth) keyboards not supported
|
|
* Graceful disconnect/reconnect from uSynergy.
|
|
* Copy/Paste not well-supported
|
|
|
|
## C++ on iOS / OSX
|
|
|
|
ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.
|
|
|
|
Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.
|
|
|
|
In my case, most of my game code is already in C++ so it's not really an issue and I can use ImGui directly.
