ios - SDL 和 iOS main() 方法冲突

Question

我了解到SDL项目需要main()方法来运行循环，代码如下:

#include "SDL.h"

int main(int argc, char *argv[])
{
    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        printf("%s\n", SDL_GetError());
    }

    SDL_Window *window = SDL_CreateWindow(NULL, 0, 0, 320, 640, SDL_WINDOW_OPENGL | SDL_WINDOW_FULLSCREEN);
    SDL_Renderer *renderer = SDL_CreateRenderer(window, 0, 0);

    SDL_Surface *bmp_surface = SDL_LoadBMP("space.bmp");
    SDL_Texture *space = SDL_CreateTextureFromSurface(renderer, bmp_surface);
    SDL_FreeSurface(bmp_surface);

    SDL_RenderCopy(renderer, space, NULL, NULL);
    SDL_RenderPresent(renderer);

    int done = 0;
    while (!done) {
        Uint32 startFrame = SDL_GetTicks();
        SDL_Event event;
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                done = 1;
            }
        }
        Uint32 endFrame = SDL_GetTicks();

        Sint32 delay = MILLESECONDS_PER_FRAME - (endFrame - startFrame);
        if (delay < 0) {
            delay = 0;
        } else if (delay > MILLESECONDS_PER_FRAME) {
            delay = MILLESECONDS_PER_FRAME;
        }
        SDL_Delay(delay);
    }

    SDL_DestroyTexture(space);
    SDL_Quit();

    return 0;
}

iOS项目还需要main()方法，代码如下:

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

int main(int argc, char * argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

现在我需要将SDL库集成到iOS项目中，但需要两个main()方法。如何？如果是，有人可以显示更多代码吗？谢谢。

您需要获取 SDLMain.m 和 SDLMain.h
