    <p>The following code creates a snapshot of the enclosing view (superview of <code>faceImageView</code> with <code>clipsToBounds</code> set to <code>YES</code>) using a calculated scale factor.</p> <p>It assumes that the content mode of faceImageView is <code>UIViewContentModeScaleAspectFit</code> and that the frame of faceImageView is set to the enclosingView's bounds.</p> <pre><code>- (UIImage *)captureView { float imageScale = sqrtf(powf(faceImageView.transform.a, 2.f) + powf(faceImageView.transform.c, 2.f)); CGFloat widthScale = faceImageView.bounds.size.width / faceImageView.image.size.width; CGFloat heightScale = faceImageView.bounds.size.height / faceImageView.image.size.height; float contentScale = MIN(widthScale, heightScale); float effectiveScale = imageScale * contentScale; CGSize captureSize = CGSizeMake(enclosingView.bounds.size.width / effectiveScale, enclosingView.bounds.size.height / effectiveScale); NSLog(@"effectiveScale = %0.2f, captureSize = %@", effectiveScale, NSStringFromCGSize(captureSize)); UIGraphicsBeginImageContextWithOptions(captureSize, YES, 0.0); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextScaleCTM(context, 1/effectiveScale, 1/effectiveScale); [enclosingView.layer renderInContext:context]; UIImage *img = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return img; } </code></pre> <p>Depending on the current transform the resulting image will have a different size. For example when you zoom in, the size gets smaller. You can also set <code>effectiveScale</code> to a constant value in order to get an image with a constant size.</p> <p>Your gesture recognizer code does not limit the scale factor, i.e. you can zoom out/in without being limited. That can be very dangerous! My capture method can output really large images when you've zoomed out very much.</p> <p>If you have zoomed out the background of the captured image will be black. If you want it to be transparent, you must set the opaque-parameter of <code>UIGraphicsBeginImageContextWithOptions</code> to <code>NO</code>.</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.
