Question

I writed a simple code to get string value from a web server, now I wanna to set timeout, like, do getData 10 sec then if server not responding after 10 second cancel getting data and do “noConnect”. any idea how can I do that?

-(void)getData {
NSURL *url = [NSURL URLWithString: [NSString stringWithFormat:
@"http://exaple.com/example.plist"]];
NSDictionary *data = [NSDictionary dictionaryWithContentsOfURL:url];
NSString *aKey  = [chamUpdateData objectForKey:@"count"];
}
-(void)noConnect{}

You could wrap the call to dictionaryWith... in an NSOperation in order to execute it asynchronously; then start an NSTimer so that then it fires, you can check the status of the NSOperation; if it is still running, then you cancel it.

Keep in mind that there is no way I know of to actually stop the network request, once you have sent it. So, you simply have a timeout to manage the case when the connection takes longer than that. If the response arrives in 1 minute, you will simply ignore that data.
