    <p>I'm syncing my Mac application with my iPhone application using NSStream and am trying to encrypt the communication with SSL. I've tried to run <code>CFReadStreamSetProperty(readStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings)</code> on the iPhone side and <code>CFWriteStreamSetProperty(writeStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings)</code> on the Mac side when I set up the NSInputStream and NSOutputStream respectively. For the settings dictionary, I'm following the advice of <a href="http://iphonedevelopment.blogspot.com/2010/05/nsstream-tcp-and-ssl.html" rel="nofollow">http://iphonedevelopment.blogspot.com/2010/05/nsstream-tcp-and-ssl.html</a> and ignoring the properties of the certificate. However, encrypting it in this way doesn't seem to work as the transfer does not go through - is there something else I need to do to get this functionality working?</p> <p>Thanks!</p> <p>EDIT: Here's some code:</p> <p>On the Mac:</p> <pre><code>NSOutputStream *outStream; [service getInputStream:nil outputStream:&amp;outStream]; [outStream open]; [outStream setProperty:NSStreamSocketSecurityLevelNegotiatedSSL forKey:NSStreamSocketSecurityLevelKey]; NSDictionary *settings = [[NSDictionary alloc] initWithObjectsAndKeys: [NSNumber numberWithBool:YES], kCFStreamSSLAllowsExpiredCertificates, [NSNumber numberWithBool:YES], kCFStreamSSLAllowsAnyRoot, [NSNumber numberWithBool:NO], kCFStreamSSLValidatesCertificateChain, kCFNull,kCFStreamSSLPeerName, nil]; CFWriteStreamSetProperty((CFWriteStreamRef)outStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings); int bytes = [outStream write:[rawPacket bytes] maxLength:[rawPacket length]]; [outStream close]; </code></pre> <p>On the iPhone:</p> <pre><code>CFReadStreamRef readStream; NSString *filePath = [NSHomeDirectory() stringByAppendingPathComponent:@"file"]; NSOutputStream *fileStream = [NSOutputStream outputStreamToFileAtPath:self.filePath append:NO]; [fileStream open]; CFStreamCreatePairWithSocket(NULL, fd, &amp;readStream, NULL); NSInputStream *networkStream = (NSInputStream *) readStream; CFRelease(readStream); [networkStream setProperty:(id)kCFBooleanTrue forKey:(NSString *)kCFStreamPropertyShouldCloseNativeSocket]; networkStream.delegate = self; [networkStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [networkStream open]; [self.networkStream setProperty:NSStreamSocketSecurityLevelNegotiatedSSL forKey:NSStreamSocketSecurityLevelKey]; NSDictionary *settings = [[NSDictionary alloc] initWithObjectsAndKeys: [NSNumber numberWithBool:YES], kCFStreamSSLAllowsExpiredCertificates, [NSNumber numberWithBool:YES], kCFStreamSSLAllowsAnyRoot, [NSNumber numberWithBool:NO], kCFStreamSSLValidatesCertificateChain, kCFNull,kCFStreamSSLPeerName, nil]; CFReadStreamSetProperty((CFReadStreamRef)self.networkStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings); </code></pre>

    2. CO@Prakash On the mac it writes "-1 bytes" and on the iPhone it stops the receive with status "Stream open error".

    3. CO@Prakash - one thing to mention here. If you plan to use SSL, you have to fullfil the export compliance for encryption! Even when using the built-in SSL functionality of iOS, you need to get an export compliance from the US government.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
