PhoneGap and Jquery Mobile – A Truly Winning Combination

Published on Sep 11, 2012 by Jamie Munro

Any regular readers may have noticed that I finally got around to updating and adding a new book under "My Books" on the right-hand side of the screen.  Yes, I not-so recently published my third book (and second with O'Reilly) earlier this year.

The book is called 20 Recipes for Programming PhoneGap – Cross-Platform Mobile Development for Android and iPhone.  Throughout this book, I get you up and running quickly using the PhoneGap API along with the Jquery Mobile API to take care of the pesky mobile design issues.

Much like I did when I released my MVC 3.NET book, I provided a free chapter from the book for my readers.  Well here is an excellent recipe sample from my PhoneGap book.  The goal of this recipe is to provide a standard approach to automatically fire (or trigger) a JavaScript function when a PhoneGap page has loaded – either on initial launch or after the user has navigated within the application.

iPhone Apps Randomly Crashing?

Published on Feb 4, 2010 by Jamie Munro

Today at work I was advancing one of our iPhone applications.  It's a pretty basic application, has a menu which displays some data from the web via XML; all of that fun stuff.

On occasion, I would try to push a view controller and the application would randomly crash, e.g.:



-(void) showMainMenu {

[mainNavigationController pushViewController:mainMenuViewController animated:YES];

}
