    <p>I'm working on catching a seriously insidious bug that's happening in my code. The problem is, the bug is completely random and can happen either 9 minutes into the application's runtime or 30 minutes. I've gone ahead and added the fabulous PLCrashReporter to my project (<a href="http://code.google.com/p/plcrashreporter" rel="nofollow noreferrer">http://code.google.com/p/plcrashreporter</a>) and that works fine for trivial bugs. Also, when I'm in doubt, I will navigate to the crash logs found in ~/Library/Logs/CrashReporter/MobileDevice/ and run symbolicatecrash on the crash log. This + GDB will eventually catch any bug, except for the one I'm facing now. </p> <p>Apparently the nature of this bug is preventing even Apple's crash logs to be properly written to storage. This shows when I sync my iPhone or iPod Touch with iTunes and run symbolicatecrash on my app:</p> <pre><code>sf$ symbolicatecrash foo.crash No crash report version in foo.crash at /usr/local/bin/symbolicatecrash line 741. </code></pre> <p>It might be that my application is not leaving a crash report at all, and exiting due to memory issues. I do indeed see the applicationWillTerminate: executing my NSLog statement before exiting, in my App Delegate. However, after running the application through ObjectAlloc, my application never reaches > 2.08MB of usage. Although if I'm reading the results proper, I did allocate over 28MB of memory throughout the entire duration of my test run. </p> <p>Thanks again for everything.</p>

    1. COAre you sure your application is crashing and is not being terminated due to low memory conditions? If it's terminated by the OS then AFAIK no crash log will be generated.

    2. COI think out-of-memory is the classic "exited with code 101", but maybe I'm misremembering.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
