我用Firefox Selenium进行了一些测试,然后将它导出到Ruby.尽管测试在Firefox中运行良好,但我在Ruby中运行相同的套件时遇到了麻烦.

我试图运行他们拥有的一个示例程序,我也得到了相同的连接拒绝错误.这是我在尝试运行google_test套件时遇到的错误.

有人可以帮我弄这个吗？

编辑 这是我试过的google_test.rb

#!/usr/bin/env ruby …

我希望我的应用程序只使用前置摄像头.所以我已经实现了以下代码.

if ([UIImagePickerControllerisCameraDeviceAvailable:UIImagePickerControllerCameraDeviceFront]) {
   self.imagePickerController.cameraDevice = UIImagePickerControllerCameraDeviceFront;
}

这是我第一次打开相机时(它使用前置摄像头).但如果我取消照片然后重新进入相​​机,它将使用后置摄像头.

每次取消/重新进入相​​机时,它会在前后摄像头之间切换......

有什么我想念的吗？

我正在使用管道和分支的程序,需要将写入结束更改为输出文件.但是当我打开一个文件时,文件描述符为0,这通常是stdin,但我认为这是我的一些问题的原因.这是我的代码

if (outputfd = open("file", O_RDWR | O_CREAT | O_TRUNC) == -1) 
{
    // open failed
}

有人能告诉我为什么它是0吗？或者如何解决？

我试图导入.obj文件,但甚至无法呈现三角形.这是我正在尝试做的只是为了测试它是否可以展示一些东西.

glBegin(GL_TRIANGLES);
    glColor3f(0.5, 0.5, 0.5);
    glVertex3f(0, 0, 0);
    glVertex3f(1, 1, 1);
    glVertex3f(2, 2, 2);
glEnd();

这不会显示任何内容.但是,当我为GL_LINES更改GL_TRIANGLES时,它会显示该行.

如何显示三角形？
