how can we know iphone has got information from Internet? -

-

When I search from the internet, I want to display the activity indicator. But how can I know that the Internet to the iPhone Get feedback from the animating activity pointer to stop? Is there any way?

Take a look at the representative methods, especially, the connection: receipt response: and connectionDidFinish Loading:

Under the connection: didReiveiveResponse: Representative method that you can display Like the Network Activity Indicator: 

  - (zero) connection: (NSURLConnection *) connection did the reception response: (NSURLResponse *) response [[UIApplication shared application] .networkActivityIndicatorVisible = YE S; // ...}

and then hide it in the connection: DidFinish is loading: 

  - ( Zero) connectionDidFinish Loading: (NSURLConnection *) Connection [[UIApplication shared application] .networkActivityIndicatorVisible = NO; // ...}

You should also hide it in the connection: didFailWithError: Your connection attempt must be unsuccessful.

It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP.
