    <p>This should work. I commented in the code to help you understand what's going on:</p> <pre><code>//To take advantage of CIFilters, you have to import the Core Image framework #import &lt;CoreImage/CoreImage.h&gt; //Get a UIImage from the UIView UIGraphicsBeginImageContext(myView.bounds.size); [myView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); //Blur the UIImage with a CIFilter CIImage *imageToBlur = [CIImage imageWithCGImage:viewImage.CGImage]; CIFilter *gaussianBlurFilter = [CIFilter filterWithName: @"CIGaussianBlur"]; [gaussianBlurFilter setValue:imageToBlur forKey: @"inputImage"]; [gaussianBlurFilter setValue:[NSNumber numberWithFloat: 10] forKey: @"inputRadius"]; CIImage *resultImage = [gaussianBlurFilter valueForKey: @"outputImage"]; UIImage *endImage = [[UIImage alloc] initWithCIImage:resultImage]; //Place the UIImage in a UIImageView UIImageView *newView = [[UIImageView alloc] initWithFrame:self.view.bounds]; newView.image = endImage; [self.view addSubview:newView]; </code></pre> <p>If you have any questions about the code, just leave it in the comments.</p> <p><strong>Note:</strong> CIGaussianBlur isn't present on iOS as of 5.1, so you must find a different way to blur the view for devices 5.x+ (Thanks to @BradLarson for this tip). The accepted answer in <a href="https://stackoverflow.com/questions/16182788/how-to-get-the-gaussian-blur-effect-on-a-uiview-in-ios6">this question</a> looks promising as a replacement, as does <a href="https://github.com/alexdrone/ios-realtimeblur" rel="nofollow noreferrer">this library</a>.</p>

    1. CONote that CIGaussianBlur isn't present on iOS as of 5.1, so you may need to find a different way of accomplishing this on 5.x and older.

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).
