NSURLConnection doesn't start

I am writing location based app, get weather information through API by using NSURLConnection for current/other places .At first time I sent request its working successfully. But next time I want to refer the information for same place it not working while NSURLConnection is not call the any delegate methods.

this is my code:

NSString *strs=[@"http://www.earthtools.org/timezone-1.1/" stringByAppendingString:[NSString stringWithFormat:@"%@/%@",place.latitude,place.longitude]];

NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:strs]];

self.reqTimeZone=[NSURLConnection connectionWithRequest:request delegate:self];
[self.reqTimeZone start];

I assume you mean NSURLConnection (NSConnection doesn't exist). NSURLConnection can only be used once. See Reusing an instance of NSURLConnection.

Another gotcha with NSURLConnection is that it must be ran on a thread with a runloop. The main thread automatically has a run loop, but methods called on GCD and NSOperation threads need to have the runloop created explicitly. In practice you probably don't need to run NSURLConnection on a background thread. The download operation will not block the main thread. If you do decide to run NSURLConnection on a run loop the easiest way to do it is probably to create an NSOperation subclass and create the run loop inside of -main.
