GameKit/GameCenter - I386

Question

我在iOS GameCenter上遇到了一些困难,我正在关注youtube上的一些教程, 但是一旦我完成代码,我就会收到这个错误:

Answer 1

看起来您还没有将GameKit框架添加到您的项目中.

如果你使用Xcode 3.2.x:

• 右键单击Frameworks文件树中的组/文件夹(在xcode窗口的左侧)
• 按Add,然后选择Existing Frameworks...
• 滚动GameKit.framework并双击它

如果你使用Xcode 4:

• 在文件树中,单击项目(顶部的项目)
• 选择目标
• 转到Build Phases主面板上的选项卡
• 展开 Link Binary with Libraries
• 按+按钮
• 滚动到GameKit.framework并双击它.
