    <p>This drove me absolutely nuts too. I did a couple of things that made it work, but I'm not happy about my solutions -- 1) I don't really understand it and 2) it seems hacky.</p> <p>I added this to my app delegate (my .m file):</p> <pre><code>@interface UITabBarController (MyApp) @end @interface UINavigationController (MyApp) @end @implementation UITabBarController (MyApp) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation { return YES; } @end @implementation UINavigationController (MyApp) - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation { return YES; } @end </code></pre> <p>This worked for the most part. For the views that didn't auto-rotate though, I had to manually rotate the views myself using transforms. I did something like:</p> <pre><code>- (void)deviceOrientationDidChangeWithAnimation:(BOOL)animated { UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; if (orientation == oldOrientation) { return; } if (animated) { CGFloat duration = [UIApplication sharedApplication].statusBarOrientationAnimationDuration; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:duration]; [UIView setAnimationDidStopSelector:@selector(orientationChanged)]; } [self sizeToFitOrientation:YES]; if (animated) { [UIView commitAnimations]; } oldOrientation = orientation; } - (CGAffineTransform)transformForOrientation { UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation; if (orientation == UIInterfaceOrientationLandscapeLeft) { return CGAffineTransformMakeRotation(M_PI*1.5); // rotated CCW } else if (orientation == UIInterfaceOrientationLandscapeRight) { // CW return CGAffineTransformMakeRotation(M_PI/2); } else if (orientation == UIInterfaceOrientationPortraitUpsideDown) { // CCW return CGAffineTransformMakeRotation(-M_PI); } else { // CW return CGAffineTransformIdentity; } } - (void)sizeToFitOrientation:(BOOL)transform { if (transform) { self.view.transform = CGAffineTransformIdentity; } CGRect frame = [UIScreen mainScreen].applicationFrame; CGPoint center = CGPointMake(frame.origin.x + ceil(frame.size.width/2), frame.origin.y + ceil(frame.size.height/2)); CGFloat width = frame.size.width - 0 * 2; CGFloat height = frame.size.height - 0 * 2; UIInterfaceOrientation _orientation = [UIApplication sharedApplication].statusBarOrientation; if (UIInterfaceOrientationIsLandscape(_orientation)) { self.view.frame = CGRectMake(0, 0, height, width); } else { self.view.frame = CGRectMake(0, 0, width, height); } self.view.center = center; if (transform) { self.view.transform = [self transformForOrientation]; } } </code></pre> <p>Hope this helps! And if someone can point out mistakes I've made (or bad things I'm perpetuating), I'd be happy to learn. :)</p>

    1. COInteresting. I never thought about setting the UINavigationController so that it auto rotates. I'll defiantly try this out. I wish the UISplitView was more comprehensible to use... Thank you for the answer!

    2. COJust got the chance to try this tonight. I subclassed my UINavigationController and added the required method to enable auto-rotation. It's now working perfectly! So far, I haven't had to do any manual rotation views. Thank you very much for your solution!

    3. COThat's great! I still don't quite understand why it works, but I'm glad it does :)

Guidance
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).
