Question

我添加了所有相关框架，并导入了所有相关文件。事实上，如果我删除导入，它给了我所有方法未找到错误。任何想法如何解决这个问题？

Undefined symbols for architecture i386:
  "_rectForRectWithInset", referenced from:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

编辑：

从这些代码行中：

CGRect borderRect = rectForRectWithInset(self.bounds, 0.5);
CGMutablePathRef borderPath = createRoundedRectForRect(borderRect, 4);

他们用这些方法引用一个类。它在另一个项目中工作，具有相同的导入，相同的引用方法，相同的导入框架。

链接器错误很可能表示您错过了在目标的构建阶段中包含框架。

我不知道上述函数的实现，但我想，你错过了包含CoreGraphics或QuartzCore。你需要导入主头文件。
