Question

The network activity indicator spins in the status bar while network activity proceeds. It disappears when network activity stops.

But there’s nothing except networkActivityIndicatorVisible in UIApplication Class.

How can I get the “Network Activity Indicator” object on the status bar?
Or if there is a Notification when activity proceeds?

I need to monitor network activity.

Answer 1

Here is the information provided in UIApplication class reference::

networkActivityIndicatorVisible

A Boolean value that turns an indicator of network activity on or off.

@property(nonatomic, getter=isNetworkActivityIndicatorVisible) BOOL networkActivityIndicatorVisible

Discussion

Specify YES if the application should show network activity and NO if it should not. The default value is NO. A spinning indicator in the status bar shows network activity. The application may explicitly hide or show this indicator.

So check with isNetworkActivityIndicatorVisible. I guess this what you want.
