Question : Using XCode and Cocoa Touch - How do find info on debugging and implementing classes properly for iPhone?

I'm relatively new to development in XCode and Interface Builder for iPhone.  I've developed a little with C# in .NET for work.
I'm wanting to know a systematic approach to debugging and using classes properly in development.

For example, I'm writing an app, and I'm wanting to use a class I haven't implemented before, UIWebView.  I used the apple developer documentation in XCode to learn how to use it, but I've not been able to get a page running in the UIWebView yet.  The simulation runs without warnings or errors, but nothing loads in the UIWebView.

How I should go about solving this sort of problem?  What should I read, or what debugging steps should I take to get the UIWebView, or any class implemented properly?

I could post my code, but I more concerned about the proper steps to solving this type of issue rather than just to solve this example.

1. Use NSLog for each step.
2. Set a breakpoint new NSString *urlAddress = @"http://www.google.com"; and check the variables and function returns. In may cases you can check everything in Mac OS X application. The change is simple AppKit instead of UIKit.
