Question

In my application I am using synchronous request for call webservice. And before each call I want to update my UILabel to show the progress. like:

lblTest.text=@"Downloading data XYZ";
NSData *dati = [NSURLConnection sendSynchronousRequest:richiesta returningResponse:&response error:&error];

lblTest.text=@"Downloading data ABC";
NSData *dati = [NSURLConnection sendSynchronousRequest:richiesta returningResponse:&response error:&error];

but label text is not getting changed.

anyone having any idea on this?

After searching a lot about this issue , I got a solution.

just need to initiate thread like:

 [NSThread detachNewThreadSelector:@selector(downloadData) toTarget:self withObject:nil];

and update label text as:

 [lblTest performSelectorOnMainThread:@selector(setText:) withObject:strMessage waitUntilDone:YES];

And this resolved my issue.
