How to check if the Adobe security panel is closed
// This code checks one time if the security panel is closed.
// When you open the security panel, you should run this test
// repeatedly with a timer (every 500ms seems to work well).
// If the security panel is closed, you can then clean up your timers
protected function securityPanelIsClosed():Boolean
{
// Why not just wait for an event from the SettingsPanel to know that it's closed?  Because there isn't one.
// See http://bugs.adobe.com/jira/browse/FP-41
var closed:Boolean = true;

How to launch an iOS url-protocol-aware app via JS, but do something different if the app isn't installed

// Listen for the Safari window to be deactivated
goog.events.listen(window, goog.events.EventType.BLUR, this.onMobileAppDetected, false, this);
// Launch the mobile app protocol and *ALSO* launch a timer
// that checks if the app was launched (it would have deactivated the mobile browser)
goog.Timer.callOnce(this.launchMobileApp, 100, this);

RegexKitLite's arrayOfCaptureComponentsMatchedByRegex: written using NSRegularExpression
// I had a need to replace the use of RegexKitLite's arrayOfCaptureComponentsMatchedByRegex with
// the built-in NSRegularExpression in iOS 5+, and didn't find an existing example, so I wrote one:
- (NSArray *) arrayOfCaptureComponentsOfString:(NSString *)data matchedByRegex:(NSString *)regex
{
NSError *error = NULL;
NSRegularExpression *regExpression = [NSRegularExpression regularExpressionWithPattern:regex options:NSRegularExpressionCaseInsensitive error:&error];
NSMutableArray *test = [NSMutableArray array];

How to parse a Socket.IO payload (== packets bunched together), so that we can parse them as individual packets.
// Sometimes Socket.IO "batches" up messages in one packet,
// so we have to split them.
//
- (NSArray *)packetsFromPayload:(NSString *)payload
{
// "Batched" format is:
// �[packet_0 length]�[packet_0]�[packet_1 length]�[packet_1]�[packet_n length]�[packet_n]

Convert CLLocation and CLHeading into GPS metadata
// Inspired by: http://stackoverflow.com/a/5314634/9849
// Simplified if-statements
// Updated to "modern" syntax
// Support optional CLHeading
// Support degree-of-precision
//
// This dictionary should then be added to the normal
// metadata using the kCGImagePropertyGPSDictionary key
