Hey Guys, I am using Instruments to find memory leaks in my iPhone application. I saw a few leaks in the application however the extended details view is not showing the stacktrace. It just says "No stack trace available for this block". I am sure I have missed some settings which resulted in this behavior. Any help would be greatly ap...

I have an app that appears to run without problems in normal use. The Clang Static Analyzer reports no problems either. When I try to run it in Instruments, it fails with an unrecognized selector exception. The offending line is a simple property setter of the form: self.bar = baz; To figure out what's going on, I added an NSLog(...
I'm trying to optimize an iPhone game that I am developing which uses the Cocos2D-iphone framework. I want to use Shark to measure performance but "Run->Start with Performance Tool->Shark" is disabled in XCode (Instruments Leaks works fine). I've configured the build to "Generate Profiling Code", tried building for both the device and t...
Hi All, I'm finishing up my third iPhone App. Cleaning up code and such. I have 3 memory leaks after the launch of the application. These remain constant no matter what I do in the App (no more leaks). The issue is that my Net Object Allocation keeps growing up. There are two blocks in particulat, GeneralBlock-24 & GeneralBlock-48 that ...
Hi guys, I am developing a iPhone app and everything works fine so far. I can build and start the app in the simulator.

I was doing a memory profile in Instruments for my iPhone app and I pressed the "Full Screen" button in the lower left. The screen went black and I can't make it do anything else. When I power cycle the box I get the splash screen appearing, and then it goes back to black. Please help. Here's a doc showing the button in the lower lef...
I have been trying to perform some OpenGL ES performance optimizations in an attempt to boost the number of triangles per second that I'm able to render in my iPhone application, but I've hit a brick wall. I've tried converting my OpenGL ES data types from fixed to floating point (per Apple's recommendation), interleaving my vertex buff...

I am cleaning up my code in a phonebook iPhone application and the Leaks tool in Instruments is reporting that I am leaking NSCFString objects.

16 Bytes is pretty small, right? None of the UIImages I create in my app are that small, yet the Leaks Instrument is reporting a leaked UIimage of size 16 Bytes... Any clues on what this could be? Incidentally, there was also a leaked CALayer object of 48 bytes... ...
I am trying to free up some unused resources in my app. I have a couple MBs of an (object?) of category GeneralBlock and I have no clue what this is or how I should be approaching the freeing up of this GeneralBlock. GeneralBlock has no apparent use. When I start my app there is a MENU screen at which point in time I have about 300kb o...
I keep seeing what appears to be a memory leak - but I can't tell what to do. It looks like a memory leak in Core Data. I can see the LAST method I explicitly invoke in Objective-C, but I'm not creating any object there. I'm saving something and Core Data is leaking memory according to Leaks. Am I reading this incorrectly? ...

I'm new to using avadioplayer and I seems to have a memory when ever I play a sound. I cannot figure out what I am missing to get rid of it inside Instrument. could this be a false positive?
