The UIImagePickerController is a must for creating iPhone apps, everyone loves taking pictures and sharing them with their friends :). The UIImagePickerController is the ViewController responsible for allowing the user to either Take a Photo or to Choose a Photo from their Photo Library. And utilizing it in your code is extremely easy. I have created a short screencast showing you the basics of implementing the UIImagePickerController in MonoTouch. Note at 14 minutes in or so I sausage fingered Window.AddSubview and called it Window.AddSubView and took me a minute to figure it out :)
Hope you enjoyed the screen cast here's the code for the project I created.
