• iPhone: How do I get the title of a PDF document from within the document?

  - by Amagrammer

  Assuming I have extracted the CGPDFDictionaryRef from a PDF document using the iPhone SDK, how do I get the document's title from the dictionary? More generally, how can I get a list of the keywords for that dictionary? In theory I could ask the customer, but surely there must be some canonical keywords? Is there a list somewhere?

• iphone dylibs and frameworks are already in the device?

  - by Scott Pendleton

  Are dylibs and frameworks already in an iPhone, or does my app actually incorporate them? Also, in Xcode I see dylibs with identical names. Sometimes the subsequent names are incremented, as in libz.dylib, libz.1.dylib, libz.1.1.3.dylib, and libz.1.2.3.dylib. If I have to include libz, should I use the one with the highest rev number, assuming that that's what that is?

• Is there a standard way to display the play controls that the iPhone iPod app uses?

  - by alex

  I'm working on a music streaming app that needs play controls (skip, pause, play) just like the iPhone iPod app. I built my controls using a UIToolbar and the standard buttons. My UIToolbar controls look OK, but they're smaller than the ones that the iPod uses. Does anyone know if the iPod controls are custom graphics? Or maybe custom buttons in a UIToolbar (to get the gradient)?

• iPhone OS SDK: Possible to download SDK 3.0 w/o Xcode?

  - by Cirrostratus

  I recently downloaded the iPhone SDK 4 along with Xcode and neglected to install 3.0 and 3.1. I've since deleted the install package. I of course can re-download the whole package, but for future reference, I wonder if you are able to download individual SDK versions separately and independent of Xcode, like you would with almost any open source package.

• Remotely Installing Windows 2008 on SunBlade 6000/6250... any gotchas?

  - by Warpraptor

  I'm preparing to remotely install Windows 2008 Standard onto a 6250 blade module mounted in a SunBlade 6000 chassis rack. Are there any gotchas (aside from the predictable issues related to bandwidth in transferring the ISO, etc.) for this? Has anyone else successfully completed this task? I'm not a hardware guy, I'm a software guy who has been handed this task because the guys in the datacenter don't want to touch it. Any help is appreciated.

• How do I implement a Floodlight tag into an iPhone app?

  - by squeeze-my-lime

  A client is asking me to insert a Floodlight tag into an Objective-C programmed iPhone app that is ready for submission to the App Store. I did some Googling, and couldn't find anything about how to do this (it seems like you can you only add Floodlight tags via Javascript, but I'm not too sure). Can you do this, and, if so, how?

  - by matt

  try it out: volatile float bob = -344.0f; unsigned int fred = (unsigned int)bob; printf("%d\n",fred); output will be 0. obviously I am expecting it to wrap around just as if I had cast from a signed int to an unsgined int (which does wrap and act as expected on the iphone) we assume it is something to do with the floating point settings. any ideas?

  So, I've been trying to figure out why the square is moving up and down the iPhone simulator when Build and Go the template that Apple provides for OpenGL ES.

• Ok to implement backend/shared functionality for iPhone in JavaScript?

  - by John Wright

  Is it ok to use the Webkit Javascript engine to implement cross-platform, non-GUI backend functionality on the iPhone, iPad? In my case, I was interested in re-using Javascript code that I have that works on top of SQLite. I thought I would need to re-implement the logic in Obj-C but perhaps I could just share it and expose some hooks into Obj-C using JSCocoa or straight through JavaScript core. Is this legal per Apple guidelines?
