    <p>Ok I managed to put this together myself. Not really sure how to use a transition method, but I needed to duplicate the view in the same location and then blow it up.</p> <p><a href="http://screencast.com/t/MLTuGkIYh">http://screencast.com/t/MLTuGkIYh</a></p> <p>So in my cell that contains the big image I hook up both the pinch and tap gesture recognizers.</p> <pre><code> self.imageView.contentMode = UIViewContentModeScaleAspectFit; self.imageView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); UIPinchGestureRecognizer *pinchGesture = [[[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinchGesture:)] autorelease]; UITapGestureRecognizer *tapGesture = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)] autorelease]; tapGesture.numberOfTapsRequired = 2; self.imageView.userInteractionEnabled = YES; self.imageView.multipleTouchEnabled = YES; [self.imageView addGestureRecognizer:pinchGesture]; [self.imageView addGestureRecognizer:tapGesture]; [cell.contentView addSubview:self.imageView]; </code></pre> <p>and then here's the rest of the code. Basically when I recognized the gesture (and for pinching, make sure its finished) I place the duplicate view in the same exact location (gained via the convertRect stuff), and then animate its frame and background color. When returning from it, I do the inverse.</p> <pre><code>- (void)handlePinchGesture:(id)sender { if (((UIPinchGestureRecognizer *)sender).state == UIGestureRecognizerStateEnded) { if(((UIPinchGestureRecognizer *)sender).view == self.imageView) { if (((UIPinchGestureRecognizer *)sender).scale &gt; 1) { [self showFloorPlanFullScreen]; } } else { if (((UIPinchGestureRecognizer *)sender).scale &lt; 1) { [self closeFloorPlanFullScreen]; } } } } - (void)handleTap:(id)sender { if (((UITapGestureRecognizer *)sender).view == self.imageView) { [self showFloorPlanFullScreen]; } else { [self closeFloorPlanFullScreen]; } } - (void)showFloorPlanFullScreen { CGRect newRect = [self.imageView convertRect:self.imageView.bounds toView:[self.splitViewController.view superview]]; UIImage *image = self.imageView.image; self.fullScreenImageView = [[[UIImageView alloc] initWithImage:image] autorelease]; UIPinchGestureRecognizer *pinchGesture = [[[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(handlePinchGesture:)] autorelease]; UITapGestureRecognizer *tapGesture = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)] autorelease]; tapGesture.numberOfTapsRequired = 2; self.fullScreenImageView.userInteractionEnabled = YES; self.fullScreenImageView.multipleTouchEnabled = YES; [self.fullScreenImageView addGestureRecognizer:pinchGesture]; [self.fullScreenImageView addGestureRecognizer:tapGesture]; self.fullScreenImageView.contentMode = UIViewContentModeScaleAspectFit; self.fullScreenImageView.frame = newRect; self.fullScreenImageView.backgroundColor = [UIColor clearColor]; [[self.splitViewController.view superview] addSubview:self.fullScreenImageView]; CGRect splitViewRect = self.splitViewController.view.frame; [UIView animateWithDuration:0.5 animations:^{ self.fullScreenImageView.backgroundColor = [UIColor blackColor]; self.fullScreenImageView.frame = splitViewRect; }]; } - (void)closeFloorPlanFullScreen { CGRect newRect = [self.imageView convertRect:self.imageView.bounds toView:[self.splitViewController.view superview]]; [UIView animateWithDuration:0.5 animations:^{ self.fullScreenImageView.backgroundColor = [UIColor clearColor]; self.fullScreenImageView.frame = newRect; } completion:^(BOOL finished) { [self.fullScreenImageView removeFromSuperview]; self.fullScreenImageView = nil; }]; } </code></pre> <p>If you want the picture to actual resize while zooming, I would recommend adding the duplicate view as soon as the pinching starts (and as long as its scaling > 1) and then apply the transformation:</p> <pre><code>CGAffineTransform myTransformation = CGAffineTransformMakeScale(((UIPinchGestureRecognizer *)sender).scale, ((UIPinchGestureRecognizer *)sender).scale); self.fullScreenImageView.transform = myTransformation; </code></pre> <p>As soon as the pinching hits a end state, I would then fade in the black and adjust the frame. I decided not to go with this method as I think just recognizing the pinch out or double tap is good enough.</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.
