Use an activity indicator to show that a task is in progress. An activity indicator appears as a "gear" that is either spinning or stopped.
You control when an activity indicator animates by calling the startAnimating and stopAnimating methods. To check if the activity indicator is animating we use the isAnimating property. To automatically hide the activity indicator when animation stops, set the hidesWhenStopped property to YES.
Starting in iOS 5.0, you can set the color of the activity indicator by using the color property.
It also has an activityIndicatorViewStyle property, which can take one of the following 3 values:
UIActivityIndicatorViewStyleWhiteLarge, UIActivityIndicatorViewStyleWhite, andUIActivityIndicatorViewStyleGray.
