unity3d與Object-C互動

標籤：style   blog   color   使用   strong   檔案   

（1）unity3d 中如何調用IOS的Api

1、在C# 指令碼中使用

　(1) 需要匯入檔案 using System.Runtime.InteropServices; 

　(2) [System.Runtime.InteropServices.DllImport("__Internal")]

　     extern static public int AwesomeFunction(int awesomeParameter);

２、在unity匯出的xcode工程中的C/C++/objective-C 檔案中的任意位置, 建立一個類 unityplugin.h， unityplugin.mm

標頭檔中：

extern "C" void AwesomeFunction();

 類體中：

int AwesomeFunction(int awesomeParameter)

{

     return somethingAwesome;

}

 

具體的：

 

Unity C# 代碼

using UnityEngine;using System.Collections;using System.Runtime.InteropServices;public class testFeil : MonoBehaviour {        [DllImport("__Internal")]    private static extern void c_ctest();        void Start () {    }    void Update () {    }        void OnGUI()      {          //開始按鈕  建立了一個按鈕。          if(GUI.Button(new Rect(20,100,200,50),"qingyun "))          {               c_ctest();          }          } 
    // 這個是C#裡的一個回調。OC處理完成後 調用Unity方法    void testFaildResult (string msg)    {        Debug.Log("testResult:" +msg);    }    //這個是C#裡的一個回調。這裡的作用就是OC裡的回呼函數。    void testSuccessResult (string msg)    {        Debug.Log ("btnPressSuccess:"+msg);    }}

Object-C  .mm 檔案裡的OC  與 C 介面

 

MeiyuPushSdk.h

#import <Foundation/Foundation.h>#import <UIKit/UIKit.h>@protocol  MeiyuPushSdkDelegate;
@interface MeiyuPushSdk : NSObject@property (nonatomic, assign)id<MeiyuPushSdkDelegate> delegate;//初始化+(MeiyuPushSdk*)my_initPush;+ (void)my_setupWithOption:(NSDictionary *)launchingOption registerForRemoteNotificationTypes:(int)types ;      // 註冊APNS類型+ (void)my_registerDeviceToken:(NSData *)deviceToken;                                                           // 向伺服器上傳Device Token+ (void)my_receiveRemoteNotification:(NSDictionary *)remoteInfo;                                                // 處理收到的APNS訊息，向伺服器上傳收到APNS訊息-(void)cTest;@end@protocol MeiyuPushSdkDelegate <NSObject>@optional-(void)cTestResult;@end

 

MeiyuPushSdkC.h

#import <Foundation/Foundation.h>#ifdef __cplusplusextern "C"{#endif    void c_ctest();  #ifdef __cplusplus}#endif

MeiyuPushSdkC.mm

#import "MeiyuPushSdkC.h"#import "MeiyuPushSdk.h"@interface MeiyuPushSdkC : NSObject<MeiyuPushSdkDelegate>@end@implementation MeiyuPushSdkC- (id)init{    id object = [super init];    [[MeiyuPushSdk my_initPush]setDelegate:self];    NSLog(@"initMeiyuPushSdkC");    return object;}-(void)cTestResult{    UnitySendMessage("Main Camera", "testSuceessResult", "成功");}@endMeiyuPushSdkC *m_pushSdk = NULL;#if defined (__cplusplus)extern "C"{#endif    void c_ctest()    {        if(m_pushSdk == NULL)        {            m_pushSdk = [[MeiyuPushSdkC alloc]init];        }        MeiyuPushSdk *m = [MeiyuPushSdk my_initPush];        [m cTest];
        UnitySendMessage("Main Camera", "testFaildResult", "介面調用失敗");    }    #if defined (__cplusplus)}#endif

這樣就把Unity3d 與OC 連到了一起。
