Answers

1. The Touch Up Inside event is most commonly used to trigger actions based on a button press.

2. The @property and @synthesize directives define a property that corresponds to an instance variable. The property gives us a means of accessing our instance variables without having to manipulate them directly. In addition, a property that is declared without a corresponding instance variable automatically generates that instance variable for you; we (and Apple) take advantage of this feature throughout the book.
