[data writeToFile:@"/tmp/station.pls" atomically:YES]; ->Works perfectly
when I download a html file for example I change the code to [data
writeToFile:@"/tmp/station.html" atomically:YES]
Issue I get is
NSError *error; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL
URLWithString:@"http://yp.shoutcast.com/sbin/tunein-station.pls?id=9907";]];
NSData *data = [NSURLConnection sendSynchronousRequest:request
returningResponse:nil error:&error];
if (!data) [NSApp presentError:error];
the download happens perfectly when the URLWithString is an html file but if
it is a pls file like the example given above fails.No download happens at
all.
Thanks
Arnab
