iOS内嵌unity

参考文章：iOS原生集成unity—framework形式集成（一） - 简书 (jianshu.com)

iOS中嵌入unity和iOS与unity交互这位博主已经写得很详细了，我这里只是记录一下桥接文件与单例类

桥接文件：

NativeCallProxy.h

// [!] important set UnityFramework in Target Membership for this file
// [!]           and set Public header visibility

#import 

// NativeCallsProtocol defines protocol with methods you want to be called from managed
@protocol NativeCallsProtocol
@required
- (void) showHostMainWindow:(NSString*)color;
// other methods
@end

__attribute__ ((visibility("default")))
@interface FrameworkLibAPI : NSObject
// call it any time after UnityFrameworkLoad to set object implementing NativeCallsProtocol methods
+(void) registerAPIforNativeCalls:(id) aApi;

@end

NativeCallProxy.mm

#import 
#import "NativeCallProxy.h"


@implementation FrameworkLibAPI

id api = NULL;
+(void) registerAPIforNativeCalls:(id) aApi
{
    api = aApi;
}

@end


extern "C" {
    void showHostMainWindow(const char* color) { return [api showHostMainWindow:[NSString stringWithUTF8String:color]]; }
}

单例类：

ConfigObj.h

//
//  ConfigObj.h
//  nativeiOS
//
//  Created by ChuangshiMac on 2021/12/16.
//

#import 

NS_ASSUME_NONNULL_BEGIN

@interface ConfigObj : NSObject

@property (nonatomic, assign) int gArgc;
@property (nonatomic, assign) char** gArgv;
+(instancetype) shareInstance;

@end

NS_ASSUME_NONNULL_END

ConfigObj.m

//
//  ConfigObj.m
//  nativeiOS

#import "ConfigObj.h"

@implementation ConfigObj

static ConfigObj* _instance = nil;

+(instancetype) shareInstance
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken,^{
        _instance = [[self alloc] init];
    });
    
    return _instance;
}

@end
