# iOS / OSX example
|
||||
|
||||
## Introduction
|
||||
|
||||
THIS EXAMPLE HAS NOT BEEN MAINTAINED PROPERLY AND NEEDS A MAINTAINER.
|
||||
|
||||
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 code in example_glfw_opengl3/ 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.

# iOS / OSX Metal example
|
||||
|
||||
## Introduction
|
||||
|
||||
This example shows how to integrate Dear ImGui with Metal. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
|
||||
|
||||
(NB: you may still want to use GLFW or SDL which will also support Windows, Linux along with OSX.)

// ImGui Renderer for: Metal
|
||||
// This needs to be used along with a Platform Binding (e.g. OSX)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'MTLTexture' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
|
||||
// Missing features:
|
||||
// [ ] Renderer: Multi-viewport / platform windows.
|
||||
|
||||
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
|
||||
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
|
||||
// https://github.com/ocornut/imgui
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2018-07-05: Metal: Added new Metal backend implementation.
