    <p>Ok, I've solved it.</p> <p>First I created a category on NSBundle, and created new implementations of pretty much every method related to loading files from the bundle, until I found the one Qualcomm are using, which is:</p> <pre><code>- (NSString *)pathForResource:(NSString *)name ofType:(NSString *)ext inDirectory:(NSString *)subpath; </code></pre> <p>Once I had that, I changed my category method to be:</p> <pre><code>#define XFILPATH4DOCUMENT(_value) [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:_value] - (NSString *)pathForResourceOverride:(NSString *)name ofType:(NSString *)ext inDirectory:(NSString *)subpath { if (([name isEqualToString:@"config"] &amp;&amp; [ext isEqualToString:@"xml"]) || ([name isEqualToString:@"qcar-resources"] &amp;&amp; [ext isEqualToString:@"dat"])) { // OMG NSString *fileName = [NSString stringWithFormat:@"%@.%@", name, ext]; NSString *path = XFILPATH4DOCUMENT(fileName); NSLog(@"%@", path); return path; } else { return [self pathForResourceOverride:name ofType:ext inDirectory:subpath]; } } </code></pre> <p>Then, through the magic of method swizzling:</p> <pre><code>Swizzle([NSBundle class], @selector(pathForResource:ofType:inDirectory:), @selector(pathForResourceOverride:ofType:inDirectory:)); </code></pre> <p>Using this method:</p> <pre><code>#import &lt;objc/runtime.h&gt; #import &lt;objc/message.h&gt; void Swizzle(Class c, SEL orig, SEL replacement) { Method origMethod = class_getInstanceMethod(c, orig); Method newMethod = class_getInstanceMethod(c, replacement); if(class_addMethod(c, orig, method_getImplementation(newMethod), method_getTypeEncoding(newMethod))) class_replaceMethod(c, replacement, method_getImplementation(origMethod), method_getTypeEncoding(origMethod)); else method_exchangeImplementations(origMethod, newMethod); } </code></pre> <p>Which I got from the answer here: <a href="https://stackoverflow.com/questions/1637604/method-swizzle-on-iphone-device">Method Swizzle on iPhone device</a></p> <p>Scary? Yes.</p> <p>But it works.</p>

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).
