You can use UIImagePickerController to take picture from camera. You can refer http://developer.apple.com/library/ios/#documentation/uikit/reference/UIImagePickerController_Class/UIImagePickerController/UIImagePickerController.html

You can get an UIImage from the imagepicker which u can use according to your needs

@Anand for your camera issue take help from the 7KV7 suggest link that is the best one from the apples developer document Take image from camera and then do it what you want to do with that image.

As far as UIPickerView is concerned refer UIPickerView and also have a look at iPhone SDK Tutorial

For pickerview you have to call different delegate methods and those methods are mentioned in the tutorial i had shared you above.
