Hi, using the Adobe Digital Editions version, found these errors in the chapter:

Page 76: Should be mapView:didAddAnnotationViews:
instead of mapViewDidAddAnnotationViews: in the text.
Page 78: "For Whereami, the keyboard should display the placeholder text “Enter Location Name”"
The UITextField should display this placeholder?
Page 79,84: Missing in the code.
Page 85: Comment in code contains typo:
“If this location was made was more than 3 minutes ago”



Thanks for the corrections!
