Expected ";" before "{" token?

I am still having trouble with the WebKit tutori开发者_如何学Goal that I am trying from Apple's website: http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/DisplayWebContent/Tasks/MultipleWindows.html

The .h file is as follows:

#import <Cocoa/Cocoa.h>
#import <WebKit/WebKit.h>

@interface MyDocument : NSDocument
{
IBOutlet id webView;
IBOutlet id textField;
}

- (IBAction)connectURL:(id)sender //Provides me with the error 'Expected ";" before "{" token'
{
[[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[sender stringValue]]]];
}

@end

Can you see anything that is wrong with that and why it is giving me a problem, please?

-- Thank you!

Yes! you've got your implementation in your header file. Move this to your .m file:

- (IBAction)connectURL:(id)sender {
    [[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[sender stringValue]]]];
}

And replace it with the method declaration:

- (IBAction)connectURL:(id)sender;

This is an interface declaration, so you can't actually define a method there.

You need to only declare the method there, then put the definition in an @implementation block.
