The iPhone 20 second rule

If you didn't know it, the iPhone has two twenty second rules that developers need to pay attention to: The iPhone has a startup timer. If an application takes longer than 20 seconds to start up, it is killed by the iPhone OS. The iPhone OS will kill any application that is unresponsive for longer...

One thing I don't like about MonoTouch applications

With .NET, executables are fairly small. Every application shares the .NET Framework, so the applications don’t have their own copy of the framework. MonoTouch is not built into the iPhone. MonoTouch applications must have their own copy of the framework. MonoTouch is compiled into your application....

Safari and WebKit Development for iPhone OS 3.0

I bought this book a few weeks ago. I've been reading it and trying to absorb the features in the iPhone's version of Safari. I'm impressed. This book contains a huge amount of information about Safari on the iPhone. So, why is this important when you can have apps on the iPhone? Have you...

UIAlertView - the alert box for the iPhone

There are times when the user needs to be presented with some information or question. MonoTouch has a UIAlertView object. The UIAlertView is instantiated with a set of parameters. On the object instance, the .Show() method is called. For .NET developers, this is similar in concept to the .NET MessageBox...

Opening another application on the iPhone using NSUrl

The NSUrl class is what allows an application to open other applications within the iPhone OS while passing parameters. The calling sequence is fairly simple.

UIPicker in the iPhone with MonoTouch

The UIPicker is visually different than the drop down listbox that most .NET developers are familiar, however, it is designed to perform the same type of function. It allows users to select from a fixed set of data isntead of typing in data in a text box. Programming with it is fairly simple. Inherit...

The Mono / MonoTouch Soft Debugger

Honestly, I thought that it was really cool when the Novell guys put a soft debugger into Mono/MonoTouch so that it is possible to debug an application running on the iPhone Simulator or on the actual device.

Putting a Point on a Map in the iPhone

I wrote the following code to put a point on a map on the iPhone. It works pretty well. Basically, I draw a map, then I inherit from the MKAnnotation object and create a new constructor, go out to geocoder and get a lat lon to senter the map on, and finally, I put a point in the center of the map. I've...

My thoughts on MonoTouch as we enter 2010

What a wild and crazy last 6 months its been for my personal development direction. I've always been excited about mobile development. Every couple of years, I ask somebody at Wrox about a book on mobile development. Every time, the response is along the lines of "You are f***ing kidding."...
