GLFW 第一响应者错误

I am trying to create a simple GLFW window and a succeed but xcode gives me an error:

2016-12-14 10:16:40.412191 CREngine[830:21929] [General] ERROR: Setting <GLFWContentView: 0x100369850> as the first responder for window <GLFWWindow: 0x10033ea00>, but it is in a different window ((null))! This would eventually crash when the view is freed. The first responder will be set to nil.

我使用的代码是:

#include <GLFW/glfw3.h>

int main(void)
{
    GLFWwindow* window;

    /* Initialize the library */
    if (!glfwInit())
        return -1;

    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 2);
    glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

    /* Create a windowed mode window and its OpenGL context */
    window = glfwCreateWindow(640, 480, "Hello World", NULL, NULL);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);

    /* Loop until the user closes the window */
    while (!glfwWindowShouldClose(window))
    {
        /* Render here */
        glClear(GL_COLOR_BUFFER_BIT);

        /* Swap front and back buffers */
        glfwSwapBuffers(window);

        /* Poll for and process events */
        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

让我感到困惑的部分来自我所查找的内容，包括我将允许它在 mac 上运行的提示，但由于某种原因，我仍然遇到错误，所以我希望有人可以帮助我解决这个错误.
