Answer 1

Every thing you need is here: MKMApView and here MKAnnotations

Some a nice example code: WeatherMap

Answer 2

You need to create a model object that conforms to the MKAnnotation protocol. At the very least, it should implement the coordinate method (which returns a CLLocationCoordinate2D struct for your latitude and longitude). If you want to display a callout for the map pin, you'll also need to implement the title method.

You should create one of these objects for each lat,lon pair, and store these in your array. Then call the addAnnotations: on your mapView with the array of objects
