“The application-identifier entitlement is not formatted correctly; it should contain your 10-character App ID Seed, followed by a dot, followed by your bundle identifier.”

From what I can tell, the way to fix this to create a NEW entitlements file (see my previous post on creating adhoc builds for instructions on how to do this).  Previously we’d only had to create an entitlements file and uncheck “get-task-allow”.

However now it appears you also need to add a new “keychain-access-group” and add an item which includes your App Identifier (get this from the iTunes Provisioning Portal) and your bundle identifier (com.mycompany.bundle_name).

See an example below:

First, setup your audio session to record audio:

NSURL *url = [NSURL fileURLWithPath:@"/dev/null"];
NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
   [NSNumber numberWithFloat: 44100.0],                 AVSampleRateKey,
   [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,
   [NSNumber numberWithInt: 1],                         AVNumberOfChannelsKey,
   [NSNumber numberWithInt: AVAudioQualityMax],         AVEncoderAudioQualityKey, nil];

recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error];
if (recorder) {
   [recorder prepareToRecord];
   recorder.meteringEnabled = YES;
   [recorder record];
} else {
   NSLog(@"Error: %@", error);
}

Then tell the device you want to record and play audio at the same time:

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
NSError *err = nil;
[audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err];

Then, and this is the key, allow the volume from the speakers to also be loud when recording:

UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,
sizeof(audioRouteOverride),&audioRouteOverride);

The end result? You can happily play audio at full volume while recording from the device’s microphone. Happy days.

Taking inspiration from origami in it’s design, look and feel, the website is a nice example of the power of WordPress to produce effective platforms to inform customers of your services.

If you’re getting an XML error when you’re using Facebook Connect to post to a users stream using the function:

$facebook->render_prompt_feed_url()

Then ensure the following:

• You don’t have any double quotes in your attachment
• You don’t have any ampersands in your return URL

For some reason the content is being placed in a hidden field on the page on “mobile” devices.  This isn’t escaping the contents of the post, and hence breaks if you have any of the above.

Highly frustrating!  Hope this helps someone.

After the recent release to developers of iPhone SDK 4.0, the inevitable scramble to review the new APIs has been on in earnest.  One of the first things noticed were the following new AVCaptureDevice class properties:

• AVCaptureDevice – isFlashMode Supported
• AVCaptureDevice – isTorchMode Supported
• AVCaptureDevice – position (Front or Rear)

These new properties relating to the iPhone SDK class AVCaptureDevice, a class used for audio and video capture and management, suggest that the new iPhone (to be announced at WWDC 2010??) may well include a “Flash”, a “Torch” and a front camera.

If this was to turn out to be true, then a front camera for the phone would make video calls possible, the ability to take photos while viewing the camera feed, and the flash would allow you to take photos in the dark!

All very cool new potential features.  Let’s keep our fingers crossed that this turns out to be the case!

Aimed at product designers, industrial designers, product developers, engineers, environmental managers and brand owners the tool provides three key features:

• Compliance Navigator – a compliance guidance tool, covering EU RoHS, EU Batteries and EPEAT with EuP and many other compliance requirements to be rolled out over the coming weeks and months
• Lifecycle Designer – an easy to use and powerful LCA tool backed by data from the Swiss EcoInvent database
• ecoCompare – a powerful material/process/transport/waste comparison tool

It’s clear that the tool has been developed with usability in mind, providing a unique and powerful web-based tool for the design community.

This takes an iCal URL and provides you with a CSV file as a download.  Makes it much easier to get a list of dates from ICS files and use them for other purposes.

Also available is the CSV2SQL converter that I made last year, taking CSV files and coverting them into INSERT/UPDATE statements for use on a database.

Hold down the “option” key and then go to the “Virtual Machine” menu option. You’ll notice that the options switch from “Shutdown” to “Force Shutdown” when you hold down the “option” key.  Simply choose your required “Force” option and you should be back in business!

How do you do this?  I’d recommend taking the following steps:

1. Get this great OAuth Twitter PHP library from Abraham Williams
2. Sign up for a Twitter application and get an application setup.  You’ll need the “Consumer Key” and “Consumer Secret” values from Twitter. You will also need to set a “callback url” that Twitter will send the user back to.  Make sure you set this correctly.
3. Include the “twitterOAuth.php” library provided by Adbraham Williams in your code

Now, the process through which OAuth works with Twitter (and any other platform) is as follows:

Firstly, you need to get the user to authenticate with twitter and permit your application to perform actions on their behalf.  To do this, you need to send the user to twitter with a special “authorisation token”.

You request an authorisation token from Twitter, using your Consumer Key and Consumer Secret values you obtained when you signed up for a Twitter Application:

$connection = new TwitterOAuth($consumer_key, $consumer_secret);
$request_token = $connection->getRequestToken();

The $request_token returned contains the “request token” information, which you should store somewhere:

$userData['Twitter_Request_Token'] = $token = $request_token['oauth_token'];
$userData['Twitter_Request_Token_Secret'] = $request_token['oauth_token_secret'];
$db->Save_User_Data($userData); // Replace with your own saving method

Now that you have your request token, you can send the user off to Twitter to authenticate:

$authenticateUrl = $connection->getAuthorizeURL($token);
header("Location: $authenticateUrl");
exit;

Twitter will now authenticate the user and confirm they want your application to have access to their account.  Your next interaction will be on the “callback url” you setup when you created your Twitter application.  In this script you will need to use the “twitter request tokens” you saved previously to then request the “Access token” from Twitter:

$to = new TwitterOAuth($consumer_key, $consumer_secret,
$userData['Twitter_Request_Token'], $userData['Twitter_Request_Token_Secret']);
$tok = $to->getAccessToken();

Now that you’ve got the access token, you should save it as you’ll use this in future requests to Twitter:

$userData['Twitter_Access_Token'] 	= $tok['oauth_token'];
$userData['Twitter_Access_Token_Secret'] = $tok['oauth_token_secret'];
$db->Save_User_Data($userData);

Now confirm you have access to the user on Twitter:

$to = new TwitterOAuth($consumer_key, $consumer_secret,
$userData['Twitter_Access_Token'], $userData['Twitter_Access_Token_Secret']);
$result = json_decode($to->OAuthRequest('https://twitter.com/account/verify_credentials.json', array(), 'GET'));
if ($result->id){
// Everything is fine
}

Now you have access to Twitter via OAuth!  You can now run commands like this:

$to = new TwitterOAuth($consumer_key, $consumer_secret, $access_token, $access_token_secret);
$result = json_decode($to->OAuthRequest(
      'https://twitter.com/statuses/update.json',
       array('status' => $tweet), 'POST'));

The above should give you a few pointers on how to actually get up and running using OAuth/PHP on Twitter.  I hope this post helps a few people get it all working.
