Response to: Compile warnings expected?
Jamie, Glad you like the article. Good news is that a third part of the article is already in the hands of the editor and going to be published next friday, so that should make up for some of the article length. As for your warnings, as a rule it is ok but not advisable to ignore warnings that come from XCode/GCC. Warnings come when the compiler (GCC in the default existance) is confused about something, but nothing is actually wrong with the code. They often happen because the code calls a method within in a class that GCC can't identify. In this instance Objective C gets these warnings because "WebFrame.h" has not been included, so it can not determine if "loadRequest" is one of WebFrame's methods. You can ignore this because "loadRequest" is one of WebFrame's methods, but if you want it to go away add "#import <WebKit/WebView.h>" to "MyDocument.h". Andrew

  Nice article, always looking for more Cocoa tutorials.
  
  I was also getting the warnings, and adding an #import did fix it, however I added "#import <WebKit/WebFrame.h>" Now I get another warning:
  
  

  /Users/john/desktop/NewBrowser/MyDocument.m:102: warning: `WebDataSource' may not respond to `-request'

  
  
  I'm guessing it's just another import.

  could be. if you give me the actual code that is on line 102 (or 100-105 or so) of your MyDocument.m, I can get more of an idea of what is happening...

  I'm not at my Mac, but I believe it was this line:
  
NSString *url = [[[[frame provisionalDataSource]
request] URL]
absoluteString];

  
  I got rid of the warning by adding "#import <WebKit/WebDataSource.h>
