Talk:Programming Mac OS X with Cocoa for Beginners/Building a GUI

When I try to follow this tutorial, XCode gives me the following errors /Users/enk3/Documents/Schoolwork/XCode/HelloWorld/EKHelloView.m:38: warning: 'EKHelloView' may not respond to '-text:' /Users/enk3/Documents/Schoolwork/XCode/HelloWorld/EKHelloView.m:38: warning: 'EKHelloView' may not respond to '-setText:withSize:' when I attempt to get the slider to control the Hello World text size.

Make sure to implement the  '- (void) setText:(NSString*) text withSize:(int) size;' and ' - (NSString*)   text;' methods. I too had problems following this tutorial until realizing that I had skipped this important step. Otherwise, I feel it is an excellent presentation of Objective-C. A Thank-You to the author.
