GameKit / GameCenter - I386

Question

我在使用iOS GameCenter时遇到了一些困难，我在youtube上学习了一些教程，但是一旦我完成了代码，我就得到了这个错误：

Answer 1

看起来您还没有将GameKit框架添加到项目中。

如果您使用的是Xcode 3.2.x：

按

• 右键单击文件树中的Frameworks组/文件夹(在xcode窗口的左侧)

• Add，然后选择Existing Frameworks...

• Scroll to GameKit.framework并双击

如果您使用的是Xcode 4：

click on >在文件树中，单击项目(顶部的项)，然后选择您的目标

• 转到主面板上的Build Phases选项卡

• 展开+ button

• Scroll到GameKit.framework，然后双击它。
