    <p>I'm getting a crash that, to me, seems as though it is a bug in the way that Apple is handling the <code>goToDefaultLocation</code> message of MKMapView. That message in turn calls <code>[ALCityManager localeWithCode:]</code>, which calls <code>[NSLocale componentsFromLocaleIdentifier:]</code> which calls <code>CFLocaleCreateComponentsFromLocaleIdentifier</code> which calls <code>CFStringGetLength</code> and the crash occurs.</p> <p>Can someone help to point me in the direction of either fixing the bug, if it is my code that is causing this, or, helping me find a workaround if, in fact, this is a bug in Apple's code (unlikely??). </p> <p>Crash log below:</p> <pre> Incident Identifier: 84198BB6-45BD-493B-955F-75CCB5246DDD CrashReporter Key: 7dbf53bf1f1a3635d7c3c49e726dedc609ed9f3a Hardware Model: iPhone3,1 Process: MyApp [340] Path: /var/mobile/Applications/DCE9A5A1-8E24-4D4F-A1ED-9855C6CA1742/MyApp.app/MyApp Identifier: MyApp Version: ???

    1. COIt's hard to know if there's a bug in your code unless you post your code. goToDefaultLocation isn't a documented public method of MKMapView. What are you actually doing in your code when this crash occurs?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
