前言废话：开发手机游戏都知道，你要接入各种平台的SDK。那就需要Unity3d与iOS中Objective-C的函数有交互，所以你就需要用到如下内容：

一、Unity3d To iOS：

1、创建一个C#文件 SdkToIOS.cs 这是调用iOS函数的接口：

[csharp] view plain copy print ?

public class SdkToIOS: MonoBehaviour
{
//平台接入开关
public static bool isOpenPlatform = false;
//导入定义到.m文件中的C函数
[DllImport("__Internal")]
private static extern void _PlatformInit();
//定义接口函数供游戏逻辑调用
public static void InitSDK()
{
if (isOpenPlatform)
{
_PlatformInit();
}
}
}

2、编写与接口对应的Objective-c函数：

[objc] view plain copy print ?

// MyIOSSdk.h
#import <Foundation/Foundation.h>
@interface MyIOSSdk : NSObject
@end

[objc] view plain copy print ?

// MyIOSSdk.m
#import "MyIOSSdk.h"
//这里引用SDK的头文件
#import "SDKPlatform.h"
#if defined(__cplusplus)
extern "C"{
#endif
extern void UnitySendMessage(const charchar *, const charchar *, const charchar *);
extern NSString* _CreateNSString (const char* string);
#if defined(__cplusplus)
}
#endif
//*****************************************************************************
@implementation MyIOSSdk
//**********************
//message tools
+ (void)sendU3dMessage:(NSString *)messageName param:(NSDictionary *)dict
{
NSString *param = @"";
if ( nil != dict ) {
for (NSString *key in dict)
{
if ([param length] == 0)
{
param = [param stringByAppendingFormat:@"%@=%@", key, [dict valueForKey:key]];
}
else
{
param = [param stringByAppendingFormat:@"&%@=%@", key, [dict valueForKey:key]];
}
}
}
UnitySendMessage("SDK_Object", [messageName UTF8String], [param UTF8String]);
}
//**********************
//SDK fun
//初始化SDK
-(void)SDKInit
{
SDKcfg *cfg = [[[SDKcfg alloc] init] autorelease];
cfg.appid =123456;
cfg.appKey =@"aoaoaoaoaoaoaoaoaoaoaoaoaaoaoaoaoaoaoao";
cfg.orientation = UIDeviceOrientationLandscapeLeft;
//调用SDK的初始化函数
[[SDKPlatform defaultPlatform] SDKInit:cfg];
//添加回调监听
[[SDKPlatform defaultPlatform] addObserver:self selector:@selector(SNSInitResult:) name:(NSString *)kInitNotification object:nil];
}
//获取用户ID
-(NSString*)SDKGetUserID
{
[[SDKPlatform defaultPlatform] SDKGetUserID];
}
//**********************
//call back fun
//初始化更新回调
- (void)SNSInitResult:(NSNotification *)notify
{
[MyIOSSdk sendU3dMessage:@"SDKMsgInit" param:nil];
}
@end
//*****************************************************************************
#if defined(__cplusplus)
extern "C"{
#endif
//字符串转化的工具函数
NSString* _CreateNSString (const char* string)
{
if (string)
return [NSString stringWithUTF8String: string];
else
return [NSString stringWithUTF8String: ""];
}
char* _MakeStringCopy( const char* string)
{
if (NULL == string) {
return NULL;
}
char* res = (char*)malloc(strlen(string)+1);
strcpy(res, string);
return res;
}
static MyIOSSdk *mySDK;
//供u3d调用的c函数
void _PlatformInit()
{
if(mySDK==NULL)
{
mySDK = [[MyIOSSdk alloc]init];
}
[lsSDK SDKInit];
}
//注意这个函数是返回字符串
const char* _PlatformGetUin()
{
if(lsSDK==NULL)
{
lsSDK = [[MyIOSSdk alloc]init];
}
return _MakeStringCopy([[lsSDK SDKGetUserID] UTF8String]);
}
#if defined(__cplusplus)
