It also uses UIGetScreenImage which I assume is for the second method of generating video. It also uses some IOKit functions and IOMobileFramebuffer functions. It looks like the app is grabbing an IOSurface from the IOMobileFramebufferGetLayerDefaultSurface..

Getting iPhone's battery level http://stackoverflow.com/questions/3276975/getting-iphones-battery-level self powerIterator NSLog @ Kernel said d kr power void nport powerIterator I'm still pretty sure you have to rely on IOKit in order to retrieve battery level. My application does not use UIKit as it is a low level application in which UIKit cannot.. while ago I wrote a program called iox that is similar to ioreg except it makes it easier for me to translate back to IOKit calls. When I run that on my laptop I see the following with a battery level. AppleSmartBattery IOService AppleACPIPlatformExpert.. program like ioreg that you can run on the iPhone or writing something simple to log the equivalent. ioreg is part of IOKitTools and it should just compile on iPhone.

I actually found an older version to be more helpful as available here especially BusProbeClass . They all rest on IOKit for which Apple's documentation seems to be very lacking in both quantity and quality. That's heavy reading but if you check.. following is at least a test for whether an iPhone 4 is plugged in right now you'll need to link to the Foundation and IOKit frameworks #include stdio.h #import Foundation Foundation.h #import IOKit usb IOUSBLib.h #import IOKit IOCFPlugIn.h #import.. you'll need to link to the Foundation and IOKit frameworks #include stdio.h #import Foundation Foundation.h #import IOKit usb IOUSBLib.h #import IOKit IOCFPlugIn.h #import mach mach_port.h int main int argc const char argv get the port through..
