I am attempting to analyze an iPhone application using the Leaks application and everything appears to be working fine, except for when I try to view detailed information about a particular memory leak. Leaks does not appear to be loading my source code. Looking at the stack view on the right, I can see calls that reference iPhone frameworks, but anything that is referencing source code that I've written is empty. The screenshot below illustrates my point. The blocks that are light blue should be referencing my source code. Has anyone ever had this problem? Is Leaks just not finding my source

I a profiling my iPhone application on target, and according to Instruments 65% of the time is spent in mach_msg_trap . I have a background thread that runs-forever and send results back to the main thread using performSelectorOnMainThread:withObject:waitUntilDone: , aproximately every 2 seconds. I am not waiting until done. Turn out my app is not actually spending 65% of it's time in the mach_msg_trap function. It was a configuration error in Instruments on my part. The Sampler tool defaults to All Sample Counts , this will measure all threads regardless of their state. Instead switch to

I'm starting to use Instruments-Leaks with an iPhone 3G. When I try to run the app with Instruments on the iPhone I obtain Target failed to run: Remote exception encountered: 'Failed to get task for pid 280' Ideas? The only time I succeed in running the app with instruments it run very slow, I couldn't test it. What are the steps to run the app on the device searching for leaks? The solution for me was to make sure that my Profile scheme was using the "debug" and not "release" build configuration. In Xcode 4 select Product/Edit Scheme from the top menu then click on the "profile" button on the

Shark, Apple's profiler which let you configure custom performance counters, is no longer supported in OSX Mountain Lion since it can't run a 32-bit kernel. Instruments.app, Apple's replacement for Shark, doesn't seem to support reading performance counters such as L1 cache hits/misses**. Is there anyway to actually setup and read performance counters on OS X? Even if there is no application, is there some user-land API to do this? **Instruments.app does seem to have an interface for performance counters, but on my Retina MacBook Pro, the PM Events window lists no events, and indicates "Device

I just started using Instruments, a nice little tool for testing memory allocations/ leaks and all that great stuff. But I'm pretty confused at how it works... Ive looked for tutorials explaining how to work with it, but no tutorials explained what to do with it. I'll try to explain this: I have it set up to whenever I run my Xcode app, Instruments tracks everything. But the stuff that instruments record makes no sense to me. There was one leak discovered, and after that it started leaking bytes. It says the leaked object is _NSCFString and some other stuff like that. Here is a screenshot My
