You can check out the full collection at russellspence.net

Currently with offices in Melbourne and New York, Two Bulls also provide a range of specialist mobile consulting services to leading global brands and businesses.  They recently relocated their melbourne office, and to celebrate, had a cake made featuring their logo – very cool.

“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.
