Class UITextView

A UILabel is a UIView specialized for displaying a single line of text. A UITextView is a UIView specialized for displaying multiple lines of text. It knows about the newline character \n.

The text property of a UITextView is an NSString, not an NSMutableString. To change it, we must assign a new NSString object to it. We can also pop up a keyboard and let the user type new text. All the text has to be in the same font. Use a UIWebView if you want different fonts.
