The second parameter must be the encoding that the characters are currently in, not the encoding you want NSString is--at least outwardly--encoding-agnostic. It doesn't care what you feed into it, it will always spit out UTF8 unless you specify otherwise. > Still, in that case, some devices will show the parsed feed, some won’t. Separating the erros in your debugging attempts vs what might actually be happening is more useful at the moment. > I tried converting the data into NSISOLatin1 and then putting it back into > NSData using UTF8, as below, but that doesn’t help. This would be entirely pointless, as the XML parser shouldn't care what character encoding is used, as long as it is declared. UTF8 is magical for the parser. > -(void)connectionDidFinishLoading:(NSURLConnection *)connection { > NSString *dataString = [[NSString alloc] initWithData:self.dataContainer > encoding:NSISOLatin1StringEncoding]; This line is the proper way to convert the data into a string. You can then NSLog() with impunity. I would also include the data length, just to make sure that a nil result is not due to empty or nil data. > [self setDataContainer:[[dataString > dataUsingEncoding:NSUTF8StringEncoding] mutableCopy]]; > self.xmlItems = [NSMutableArray array]; > NSXMLParser *parser = [[NSXMLParser alloc] > initWithData:self.dataContainer]; > [parser setDelegate:self]; > [parser parse]; > } > > > I validated the feed’s XML and got no errors..
