title: What is no rule to process file mean?
body: <pre><code>Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/UIViewController+YIFullScreenScroll.m' of type file for architecture i386
  </code></pre>
  
  <p>I am trying to implement YIFullScreenScrollDemo</p>
  
  <p>After keep failing I just copy the whole .h and .m file to the main project. Actually I keep reference.</p>
  
  <p>Now this code for example, pass compile check:</p>
  
  <pre><code>self.fullScreenScroll = [[YIFullScreenScroll alloc] initWithViewController:self scrollView:self.tableView];
  </code></pre>
  
  <p>Yet, at run time, I got:</p>
  
  <pre><code>YIFullScreenScrollDemo[82387:c07] -[FirstViewController setFullScreenScroll:]: unrecognized selector sent to instance 0x7577e80
  </code></pre>
  
  <p>Also I got these 4 warnings:</p>
  
  <pre><code>Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/UIViewController+YIFullScreenScroll.m' of type file for architecture i386
  Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/YIFullScreenScroll.m' of type file for architecture i386
  Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../Pods/JRSwizzle/JRSwizzle.m' of type file for architecture i386
  Warning: no rule to process file '$(PROJECT_DIR)/YIFullScreenScrollDemo/../../Classes/UIView+YIFullScreenScroll.m' of type file for architecture i386
  </code></pre>
  
  <p>What is the problem?</p>
  
  <p>Note: not duplicate of the other one <a href="https://stackoverflow.com/questions/6509600/compilation-warning-no-rule-to-process-file-for-architecture-i386">compilation warning: no rule to process file for architecture i386</a></p>
  
  <p>This one is for .m files. The other question is for .h file</p>
  
  <p>Naturally we do need to include the .m files right?</p>
