My boss seems to think there's a way to play audio files via a built-in QT interface that comes up with a modal UI, much like address book framework does. Also, the mail app pops up a QT modal player to play attached audio files and then hides itself when done. I've done a good 2 hours of research and I cannot find any pre-built UI for...

I'm having some trouble getting CGColorGetConstantColor() to work on the iPhone. Apple's documentation claims you can pass any of the "Constant Colors" without linking to what the Constant Colors actually are, so I assumed you can simply use those documented for OS X: CGColorRef blackColor = CGColorGetConstantColor(kCGColorBlack); Thi...

I'm trying to figure out which property values I can rely on to store a reference to an address book contact and phone number, to avoid the potential for records to randomly change in my app. I believe I've figured out that the ABMultiValueIdentifier is the UID for an entry in a multi-value property (since it needs to be translated into ...

Hi I've searched but can't see a similar question. I've added a method to check for an internet connection per the Reachability example. It works most of the time, but when installed on the iPhone, it quite often fails even when I do have internet connectivity (only when on 3G/EDGE - WiFi is OK). Basically the code below returns NO. ...
