Unity Xcode方式接入sdk

入口

创建 GameAppController 类继承 UnityAppController
并且在类的实现之前需要加 IMPL_APP_CONTROLLER_SUBCLASS(GameAppController)，表明这个是程序的入口。UnityAppController 实现了 UIApplicationDelegate。可以简单看下 UIApplicationDelegate 的生命周期。

例：

@interface GameAppController : UnityAppController

+ (instancetype)shareAppController;

- (UIWindow*)appWindow;
@end

实现

IMPL_APP_CONTROLLER_SUBCLASS(GameAppController)

@implementation GameAppController {

@end

Unity 与 Objective-C 交互

Unity 调用 Objective-C

#define UNITY_CS_API extern "C"

/**
  微信登陆
 */
UNITY_CS_API void OCWXLogin(){
     //objective-c 代码
}

Objective-C 调用 Unity 代码

void    UnitySendMessage(const char* obj, const char* method, const char* msg);

obj 参数表示GameObject Name
method 参数表示要回调的方法名
msg 参数表示回调的方法参数

Objective-C 与 Unity 的交互要注意的是
字符串使用的是 const char* 类型，而Objective-C 中使用的是NSString* 所以需要转换
字符串作为返回值返回 需要使用 strup 函数。否则程序将闪退
返回值不能返回null 和 nil 否则闪退。所以返回值每次增加判断，如果null和nil 就用空字符串替换

例子

// const char* 转 NSString*
static inline NSString * str_c2ns(const char*s){
    if (s) {
        return [NSString stringWithUTF8String:s];
    }else{
        return [NSString stringWithUTF8String:""];
    }
}

//NSString* 转 const char*
+ (const char *) str_ns2c:(NSString *) content{
    return [content UTF8String];
}

//返回值使用 strdup 处理， 并做检查
UNITY_CS_API const char* OCReadClipBoard(){
    NSString *contentStr = [CoreManager.sharedInstance readClipBoard];
    if (contentStr == NULL || contentStr == nil) {
        contentStr = @"";
    }
    return strdup([UnityUtility str_ns2c:contentStr]);
}

Objective-C 与 Unity 交互有时会使用到Json 进行数据传输，Unity 中 Null 在 Objectiv-C 中解析将会报错，使用NullSafe 库解决. github地址

接入微信SDK

遇到报错
Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: '+[WXApi genExtraUrlByReq:withAppData:]: unrecognized selector sent to class

微信官方文档的解释是需要在 Other Linker Flags 中添加 -ObjC -all_load 进行处理。我加入-all_load 会导致编译报错，这个方法行不通。
首先sdk 的配置都是添加在 UnityFramework 而不是 Unity-iPhone 上。如果是老的Unity 应该只有 Unity-iPhone，那就是添加到Unity-iPhone上。

然后由于-all_load 行不通，所以用-force_load 代替。-force_load 后面需要加入libWeChatSDK.a 所在到路径作为参数
比如:

关于微信登录，或者分享失效，没有回调的情况，应该是漏写了调用

接入友盟和阿里支付

遇到UTDID 库冲突。这里阿里官方有解释，下载去除 UTDID 的库。下载的地方有说明
阿里的文档让人最舒服，没遇上什么问题。

Universal Links

这个如果没有配置好，微信登录将会照成2次弹窗确认。（那种给别人加企业签的就一定会有二次弹窗，因为没有teamid）
这个比较简单，随便找一个模板，替换teamid后，上传至服务器。然后在xcode中Signing & Capabilities 中的Associated Domains 配置 applinks: 域名

打包

如果使用Unity直接到处会覆盖xcode中我们写好的代码。所以把我们接入sdk的xcode代码放入Unity项目的Plugins 文件夹的iOS文件夹中。项目没有就自己创建。并把所有的第三方库也放入其中。这样打包的时候会自动导出至xCode项目。
此外xcode项目中还有一些自定义的配置。这个需要在打包流程完成后的回调中使用代码修改。
例如

string pbxProjectPath = PBXProject.GetPBXProjectPath(locationPath);
            
            //修改 Associated Domains 设置
            ProjectCapabilityManager capabilityManager =
                new ProjectCapabilityManager(pbxProjectPath, "Unity-iPhone.entitlements", "Unity-iPhone");
            capabilityManager.AddAssociatedDomains(new string[]{"applinks:cs1.jxhappy.top"});
            
            //wifi 信息
            capabilityManager.AddAccessWiFiInformation();
            
            // 百度持续定位
            capabilityManager.AddBackgroundModes(BackgroundModesOptions.LocationUpdates);
            
            capabilityManager.WriteToFile();
            
            PBXProject pbxProject = new PBXProject();
            pbxProject.ReadFromFile(pbxProjectPath);
            
            // string xCodeFrameworkPath = "./XCodeFramework";
            //
            // DirectoryInfo directoryInfo = new DirectoryInfo(xCodeFrameworkPath);
            //
            // foreach (var directory in directoryInfo.GetDirectories())
            // {
            //     ECKAddResourceGroupToiOSProject(locationPath, pbxProject, pbxProject.GetUnityFrameworkTargetGuid(),
            //         directory.Name);
            // }
            
            // 为类使用 @try @catch NULLSafe 中使用到了;
            pbxProject.SetBuildProperty(pbxProject.ProjectGuid(),"GCC_ENABLE_OBJC_EXCEPTIONS","YES"); 
            
            //Main
