如何从ObjC访问Android string资源

public class ResourceHelper {
    private static Context context;

    public static void setContext(Context ctx) {
        context = ctx;
    }

    public static String getStringResource(String resourceName) {
        int resourceId = context.getResources().getIdentifier(resourceName, "string", context.getPackageName());
        return context.getString(resourceId);
    }
}

javah -jni -classpath <path_to_android_project>/app/build/intermediates/classes/debug -d <output_directory> com.example.app.ResourceHelper

#import "com_example_app_ResourceHelper.h"

JNIEXPORT void JNICALL Java_com_example_app_ResourceHelper_setContext(JNIEnv *env, jobject obj, jobject context) {
    // 将Java的Context对象传递给Java类中的setContext方法
    jclass cls = (*env)->GetObjectClass(env, obj);
    jmethodID methodId = (*env)->GetMethodID(env, cls, "setContext", "(Landroid/content/Context;)V");
    (*env)->CallVoidMethod(env, obj, methodId, context);
}

JNIEXPORT jstring JNICALL Java_com_example_app_ResourceHelper_getStringResource(JNIEnv *env, jobject obj, jstring resourceName) {
    // 调用Java类中的getStringResource方法获取字符串资源
    jclass cls = (*env)->GetObjectClass(env, obj);
    jmethodID methodId = (*env)->GetMethodID(env, cls, "getStringResource", "(Ljava/lang/String;)Ljava/lang/String;");
    jstring result = (*env)->CallObjectMethod(env, obj, methodId, resourceName);
    return result;
}

// 导入JNI头文件
#include "com_example_app_ResourceHelper.h"

// 设置Android的Context对象
jobject androidContext = ...; // 获取Android的Context对象
Java_com_example_app_ResourceHelper_setContext(env, resourceHelperObject, androidContext);

// 获取Android string资源
jstring resourceName = (*env)->NewStringUTF(env, "my_string_resource");
jstring androidString = Java_com_example_app_ResourceHelper_getStringResource(env, resourceHelperObject, resourceName);

// 将jstring转换为NSString
const char *str = (*env)->GetStringUTFChars(env, androidString, NULL);
NSString *objcString = [NSString stringWithUTF8String:str];
(*env)->ReleaseStringUTFChars(env, androidString, str);

// 使用获取到的字符串资源
NSLog(@"%@", objcString);
