• How i can i use the value of a variable from one class in another in objective c?

  - by user337174

  Hi i am fairly new to objective c and have been doing some iphone programming. Is it possible to look up the value of a variable in a different class? Basically what i am doing is running a function that exists in my app delegate from a view controller, but the app delegate needs to use a variable stored in the view controller from which the app delegate function was called. Make sense??? Any help would be grateful. James

• Image analysis on the iPhone

  - by user362808

  Hi, guys! Hopefully a quick one. Working on a devious little algorithm that'll automatically scan a user's iPhone for a photo of some emotional poignance (e.g. go back in time a ways, look for one of a group of photos that are proximally timestamped, etc.). Need a quick-and-dirty way of picking out a photo containing two people in close proximity to each other. I know that the OpenCV Python lib [for image processing] works on the iPhone, I'm just curious whether it's actually the best way of doing this (from scratch or otherwise). Cheers!

  - by andrejs-igumenovs

  According to the Core Plot Wiki: Core Plot is built as a static library for iPhone, so you'll need to drag the libCorePlot-CocoaTouch.a static library from under the CorePlot-CocoaTouch.xcodeproj group to your target's Link Binary With Libraries folder. I do not see the mentioned library, where might it be?

• Stack Info button above UIView in Utility App

  - by bgw

  I've started creating a iPhone Utility app (main view and flip view). I want to draw some graphics in the Main view, so I dragged a UIView object onto it. This works, but I find that if I resize the UIView to fill the Main view, it covers the Info button that invokes the Flip view. Is there any way to get the Info button to appear on top of the UIView? In IB? In code?

• UIApplicationExitsOnSuspend anything else I'm missing?

  - by schone

  So I know this has been beaten to death but I still can't figure out a solution. I have my UIApplicationExitsOnSuspend set to <true/> in the Info.plist and still both in the simulator as well as on an iPhone 4 device, the app goes into standby instead of terminating? Any ideas of what else could one do to get it to terminate? Perhaps are there methods that I need to remove from the app delegate? Any ideas?

• Memory leaks in libxml2.2

  - by KSH

  I am using libxml2 to parse xml content in my iPhone app. The xml content is downloaded from a server similar to the Apple's own TopSongs sample app. When I check for leaks using the Instruments tool, I see memory leaks being reported on xmlNewParserCtxt, xmlNewInputStream and xmlAllocParserInputBuffer. I have called xmlFreeParserCtxt(context) at applicable places (dealloc). Am I missing something else ? Is this a known issue to contend with when using libxml2 parsers ?
