    <p>I believe I found the solution. If anyone else needs this functionality, here is how I got it to work:</p> <p>I used the code I found <a href="https://stackoverflow.com/questions/6113735/mpmovieplayercontroller-adding-uibutton-to-view-that-fades-with-controls">here</a> to find the MPInlineVideoOverlay subview in the MPMoviePlayer view array. Then I modified it as follows: </p> <p><pre><code> - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {</p> float newValue = 0; if([change objectForKey:NSKeyValueChangeNewKey] != [NSNull null]) { newValue = [[change objectForKey:NSKeyValueChangeNewKey] floatValue]; } NSLog(@"player controls are visible: %@", newValue ? @"YES" : @"NO"); self.controlsView.alpha = newValue; } -(void)recursiveViewTraversal:(UIView*)view counter:(int)counter { NSLog(@"Depth %d - %@", counter, view); //For debug if([view isKindOfClass:NSClassFromString(@"MPInlineVideoOverlay")]) { //Add any additional controls you want to have fade with the standard controls here mainControlsView = view; } else { for(UIView *child in [view subviews]) { [self recursiveViewTraversal:child counter:counter+1]; } } } -(void)setupAdditionalControls { //Call after you have initialized your MPMoviePlayerController (probably viewDidLoad) mainControlsView = nil; [self recursiveViewTraversal:moviePlayer.view counter:0]; //check to see if we found it, if we didn't we need to do it again in 0.1 seconds if(mainControlsView) { [mainControlsView addObserver:self forKeyPath:@"alpha" options:NSKeyValueObservingOptionNew context:NULL]; } else { [self performSelector:@selector(setupAdditionalControls) withObject:nil afterDelay:0.1]; } }` </code></pre> <p>Where mainControlsView is the standard Apple controls for MPMoviePlayer and self.controlsView is my view with my custom controls. I Key Value Observe the alpha property on the standard controls view and change mine to match whenever it changes.</p> <p>Rob</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).
