title: "symbol(s) not found for architecture i386" problem using ShareKit
body: <p>I want to use the <a href="http://getsharekit.com" rel="nofollow">http://getsharekit.com</a> framework for future iOS projects. Hence I started testing out the framework.</p>
  
  <p>But I already get the following error:</p>
  
  <pre><code>Undefined symbols for architecture i386:
  "_OBJC_CLASS_$_SHKItem", referenced from:
    objc-class-ref in ShareKitTestAppDelegate.o
  "_OBJC_CLASS_$_SHKActionSheet", referenced from:
    objc-class-ref in ShareKitTestAppDelegate.o
  ld: symbol(s) not found for architecture i386
  collect2: ld returned 1 exit status
  </code></pre>
  
  <p>Often, as far as I know, these problems arise if header files are wrongly imported. But I don't see any error here in the following code where the problem above occurs:</p>
  
  <pre><code>#import "ShareKitTestAppDelegate.h"
  #import "SHK.h"
  #import "SHKItem.h"
  #import "SHKActionSheet.h"
  - (IBAction) letshare:(id)sender
  {  
     // Create the item to share (in this example, a url)
     NSURL *url = [NSURL URLWithString:@"http://getsharekit.com"];
     SHKItem *item = [SHKItem URL:url title:@"ShareKit is Awesome!"];
  
     // Get the ShareKit action sheet
     SHKActionSheet *actionSheet = [SHKActionSheet actionSheetForItem:item];
  
     // Display the action sheet
     [self.window addSubview:actionSheet];
  }
  </code></pre>
  
  <p>I also included the ShareKit Headers Folder into HeaderSearchPath Build-Options, because of searching for all the headers.</p>
  
  <p>But I don't see any error here or anything missed. </p>
  
  <p>Can somebody help me?</p>
  
  <p>With best regards,</p>
  
  <p>Andreas</p>
