I just spent a good hour trying to diagnose a problem related to the view lifecycle in the iPhone OS, so I thought I'd share the solution here. My problem was in trying to grab some data from the network immediately after loading a view from a UITabBar.

If you are building an iPhone web app, chances are you have gotten a bit tired of relying on your device for testing changes. It can definitely be tedious to upload your changes, pick up your device, and refresh Mobile Safari each time you make a change to your code. Here's a way to use your Mac to eliminate the device (and even your internet connection) from the process.

The world of iPhone and OS X development is not an easy one to break into. There is a steep learning curve involved even for those who have experience developing on other platforms, not to mention the time it takes for a relatively green developer to learn the ropes. For this reason (among others), iPhone developers are able to charge great rates when they are commissioned to create apps.
