iOS Sample: Simple greeting and counter (C#)
In this sample, the mono runtime is used to invoke Objective-c unmanaged code (main.m) from the C# managed side (iOSSampleApp.cs) and vice versa. With the sample running, you can enter your name and click the corresponding button to modify the greeting message as well as clicking a button to increment a counter.
The purpose of this sample is to demonstrate the concept of building an iOS application on top of the mono runtime. The mono runtime headers should be supplied through the build process.
This sample will only run on macOS as it requires Xcode and an iOS simulator.
- Xcode: Any version should work with this sample (download Xcode at https://developer.apple.com/xcode/).
- iOS simulator 8.0 or greater.
- .NET sdk 6.0.100-alpha.1.20628.2.
To install a specific version of the dotnet sdk, download the latest stable version of the dotnet-install script:
Install version .NET version 6.0.100-alpha.1.20628.2:
./dotnet-install.sh --version 6.0.100-alpha.1.20628.2
IosSimulator under target
iPhone 11 to your simulator's device name.
Building the sample
The source code includes an MSBuild project file for C# (a .csproj file) that targets .NET 6.0. After downloading the .zip file, be sure to have the iOS simulator open and modify
iPhone 11 in
iOSSampleApp.csproj to the simulator's name. To run the sample, open the command line, navigate to the downloaded folder, and run
The on screen keyboard for the device can be minimized by enabling
Connect Hardware Keyboard under
Keyboard in the
I/O section of the simulator's toolbar and toggling
Toggle Software Keyboard in that same location.
