In the course of doing recipes for the Erica/Alexis project, I have learned that there are several things I need to be sure to do before modifying any of the base templates Apple provides.

1. Remember to add the app delegate string to main

When starting a new project, I am often faced with a black screen.  Despite the fact that this has happened to me three times now, it still takes me a bit of hair tearing before I remember it’s because I need to add the app delegate to the fourth parameter in the main method.

The solution to this, of course, would be to update my user templates so I don’t have to remember to do this every time.

2. Set the file’s owner to be the view controller

By default, the File Owner’s type is set to NSObject. When I have ViewControllers I want to use as a basis for my project, I need to change this so the File Owner’s type is set to my custom Root ViewController.

3. Remove the main xib line from info.plist

After changing (1) and (2), I was still getting this error: “2010-05-07 15:12:55.632 TwoItems[21829:207] Failed to load NSMainNibFile MainWindow.”

I recently picked up the Second Edition of Erica Sadun’s “The iPhone Developer’s Cookbook,” that focuses on the iPhone 3.0 SDK.

Now, admittedly, a third edition is now required given that the iPad comes along with SDK 3.2. However, I still feel that completing all 163 recipes outlined in Sadun’s book will bring me from iPhone development amateur to iPhone development expert–and give me a leg up in understanding the next version of the SDK.

So, my goal is to get through all 163 recipes over the remaining 347 days left this year.

Thanks to Julie & Julia for the inspiration on this one.
