plugin for unity to x-code

Scripting
1

Hello

I am trying to create a plugin from unity to x-code.but i don’t have any knowledge about the x-code.
what i have done so far is:

  1. created a custom class in C#:
public class CRBinding : MonoBehaviour {

 [DllImport("__Internal")]
    private static extern void _PrintMessageFromUnity (string message);
	
	public static void PrintMessageToXcode(string message)
	{
		if (Application.platform != RuntimePlatform.OSXEditor)
		{
			_PrintMessageFromUnity(message);	
		}
	}
 
 [DllImport("__Internal")]
    private static extern void _SetBadgeNumber (int badgeNumber);
	
	public static void SetBadgeNumber(int badgeNumber)
	{
		if (Application.platform != RuntimePlatform.OSXEditor)
		{
			_SetBadgeNumber(badgeNumber);
		}
	}
}
  1. also created a class in x-code :
NSString* CreateNSString (const char* string)
{
	if (string)
		return [NSString stringWithUTF8String: string];
	else
		return [NSString stringWithUTF8String: ""];
}


// When native code plugin is implemented in .mm / .cpp file, then functions
// should be surrounded with extern "C" block to conform C function naming rules

extern "C" {
    void  _SetBadgeNumber(int number)
    {
        [UIApplication sharedApplication].applicationIconBadgeNumber = number;
    }
    
    void  _PrintMessageFromUnity(const char* message)
    {
        NSString formattedMessage = CreateNSString(message);
        NSLog(@"This was sent from Unity %@",formattedMessage);
    }
}

but it gives me some error with unitypause() in x-code’s AppController.mm file while building the project.
can anyone tell me what i am doing wrong with this.or any other simple way to create a plugin for unity3d to x-code???

Thanks for the help.

Hello All,

here is my code files…

  1. Unity COde File
/// <summary>
/// Unity to Xcode tutorial.
/// </summary>
using UnityEngine;
using System.Collections;
using System.Runtime.InteropServices;

public class CRBinding : MonoBehaviour {
	public static bool xcodeCalled;
	
	[DllImport("__Internal")]
	//[DllImport ("CRBinding.mm")]
    private static extern void _PrintMessageFromUnity (string message);
	
	public static void PrintMessageToXcode(string message)
	{
		Debug.Log("in CRBinding.cs -> PrintMessageToXcode()");
		if (Application.platform != RuntimePlatform.OSXEditor)
		{
			Debug.Log("in CRBinding.cs -> PrintMessageToXcode() -> if()");
			xcodeCalled = true;
			_PrintMessageFromUnity("Hi this is message from unity");	
		}
	}
 
	[DllImport("__Internal")]
	//[DllImport ("CRBinding.mm")]
    private static extern void _SetBadgeNumber (int badgeNumber);
	
	public static void SetBadgeNumber(int badgeNumber)
	{
		if (Application.platform != RuntimePlatform.OSXEditor)
		{
			_SetBadgeNumber(badgeNumber);	
		}
	}
}
  1. X-Code Code Files
// This is just a helper method
// Converts C style string to NSString

#import "AppDelegate.m"
NSString* CreateNSString (const char* string)
{
	if (string)
		return [NSString stringWithUTF8String: string];
	else
		return [NSString stringWithUTF8String: ""];
}


// When native code plugin is implemented in .mm / .cpp file, then functions
// should be surrounded with extern "C" block to conform C function naming rules

extern "C" {
    
    /*  NSString * _PrintMessageFromUnity(const char* string)
     {
     NSString *formattedMessage = CreateNSString(string);
     NSLog(@"This was sent from Unity ");
     return formattedMessage;
     }*/
    NSString * _PrintMessageFromUnity(const char* string)
    {
        NSLog(@"This was sent from Unity ");
        AppDelegate* obj_AppDelegate = [[AppDelegate alloc]init];
        [obj_AppDelegate launchFrontend];
        NSString *formattedMessage = CreateNSString(string);
        
        return formattedMessage;
    }
}
