这是我的game.h和game.m错误是粗体。 game.h上没有任何错误。最后，它表示缺少解析需要花括号。还有缺少的标识符。通过game.h跟随游戏.m以粗体显示

@interface Game (){

当Xcode构建您的项目时，它会创建一个文件夹，将您的所有代码编译到该文件夹中的文件中，并将它们链接到您的应用程序中。更改代码时，只需重新创建受影响的文件并再次链接它们。但是，有时可能会出现文件无法更新的故障，导致代码在完全没有错误时出错。按 Shift - 命令 - K （清除）通过清除许多这些缓存和中间体来解决许多这些问题，迫使Xcode重新创建它们。如果问题仍然存在，请按选项 - Shift - 命令 - K （清洁构建文件夹）清除更多。
