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];
}
Because you can never be sure how long it will take to retrieve content from a web page and have it displayed on the iPod/iPhone, it’s quite nice to provide the user with an indication that the content is being retrieved.

This works great. I was then tasked with adding a bit of style to the view.
I started by creating all of the style in the webpage, but I quickly realized that this was causing the load to be a lot slower. Instead I had to integrate the design into the view and simply display the content from the webpage in the design.
This was going pretty well until the webpage sat like a big white blob on top of my nice image. I couldn’t let this be and had to find a solution, luckily it wasn’t to complicated. Read more »
Boy today was a frustrating day. Over the past month or so, when I have some free time at work I’ve been learning Objective C to create iPhone applications.
Today, I struggled and struggled to do the most simplistic thing ever and I wanted to share it with everyone so if you get stuck with the same problem, hopefully you will solve it a lot quicker than I did.
