Unity C # and OC call each other

Unity Two methods are generally used in combination

1.[dllimport ("__internal")] C # call OC2.UnitySendMessage OC calls C # 1 C # calls OC in C # script using Unityengine;Using System.Collections;
Using system.runtime.interopservices;//Introduction

public class Newbehaviourscript:monobehaviour {
[DllImport ("__internal")]
private static extern void CallOC (); This method is the mm file method name in OC
Use this for initialization
void Start () {
CallOC (); Call
}

Update is called once per frame
void Update () {

}
}
 in the mm file

#import

function implementation

#ifdef __cplusplus

extern "C" {

#endif

void CallOC ()

{

NSLog (@ "call to OC");

}

#ifdef __cplusplus

}

#endif

  2 OC Call unity in code unity helps me encapsulate it.Unitysendmessage in Java to notify Unity can also usefirst in the mm file//This is the addition of a button to trigger a method

UIButton *but=[uibutton Buttonwithtype:uibuttontyperoundedrect];

[But Setimage:[uiimage imagenamed:@ "Button1.png"] forstate:uicontrolstatenormal];

[But Setimage:[uiimage imagenamed:@ "Button2.png"] forstate:uicontrolstatehighlighted];

But.frame=cgrectmake (20, 20, 50, 60);

[Self.view addsubview:but];

[But Addtarget:self action: @selector (Buttoncall) forcontrolevents:uicontroleventeditingdidend];

Trigger method

-(void) buttoncall{

Unitysendmessage ("Cube", "Buttoncall", "" "); First parameter simultaneous model name 2 the model hangs the script method name 3 parameter

}

  In C #, the script hangs on a cube Using Unityengine;
Using System.Collections;
public class Newbehaviourscript:monobehaviour {
void Buttoncall () {
Debug.Log ("OC buttoncall")
}

}
