    <p>I am doing some testing in my iPhone app and I get this error:</p> <pre><code>&lt;Error&gt;: Corrupt JPEG data: bad Huffman code </code></pre> <p>I have seen some weird errors, but this one is really weird. I am also getting some other corrupt errors from it to that I can't remember. Let me post my code to write these files in order.</p> <p><strong>Step 1:</strong> Take a picture then save it</p> <pre><code>- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo { [picker.parentViewController dismissModalViewControllerAnimated:NO]; uploadImage = image; int orient = uploadImage.imageOrientation; NSString *theOrientation = [NSString stringWithFormat: @"%d", orient]; NSLog(@"Check it: 1"); NSString *latestIDQuery = @""; NSArray *results = [database executeQuery:@"SELECT * FROM processes ORDER BY id DESC LIMIT 0,1"]; for (NSDictionary *row in results) { latestIDQuery = [row valueForKey:@"id"]; } int latestID = [latestIDQuery intValue]; int newID = latestID + 1; NSString *newIDString = [[NSString alloc] initWithFormat:@"%d", newID]; NSString *imageURL = [NSString stringWithFormat:@"Documents/%@_process.jpg",newIDString]; NSLog(@"Saving here... %@", imageURL); NSString *uploadImagePath = [NSString stringWithFormat:@"%@_process.jpg",newIDString]; NSString *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:imageURL]; NSLog(@"Needs to write something like this: %@", jpgPath); [UIImageJPEGRepresentation(uploadImage, 1.0) writeToFile:jpgPath atomically:YES]; [database executeNonQuery:@"INSERT INTO processes (image, album, status, orient, ready) VALUES (?, ?, ' In Queue', ?, 'no');", uploadImagePath, selectedID, theOrientation]; TableViewAppDelegate *dataCeter = (TableViewAppDelegate *)[[UIApplication sharedApplication] delegate]; dataCeter.dataSix = nil; NSString *databaseURL = [NSString stringWithFormat:@"%@_process.jpg",newIDString]; dataCeter.dataSix = databaseURL; [self showCaption]; } </code></pre> <p><strong>Step 2:</strong> Start the uploads and possibly resize it:</p> <pre><code> NSString *sqlImageUploadPathOne = @"./../Documents/"; NSString *sqlImageUploadPathTwo = [rowtwo valueForKey:@"image"]; NSString *getCaption = [rowtwo valueForKey:@"caption"]; NSString *getTheID = [rowtwo valueForKey:@"id"]; NSString *getOrientation = [rowtwo valueForKey:@"orient"]; NSString *jpgPath = [NSString stringWithFormat:@"Documents/%@",sqlImageUploadPathTwo]; NSString *jpgPathTwo = [NSString stringWithFormat:@"./../Documents/%@",sqlImageUploadPathTwo]; NSString *yourPath = [NSHomeDirectory() stringByAppendingPathComponent:jpgPath]; // Resize and Save UIImage *tempImageTwo = [UIImage imageNamed:jpgPathTwo]; float tooBig = 800.0; UIImage *tempImage = [self scaleImage:tempImageTwo:tooBig:tooBig]; NSData *imageDataTwo = [NSData dataWithData:UIImageJPEGRepresentation(tempImage, 0.1)]; [imageDataTwo writeToFile:jpgPathTwo atomically:YES]; </code></pre> <p>And here's the function used to scale the image:</p> <pre><code>- (UIImage *)scaleImage:(UIImage *) image: (float)maxWidth:(float) maxHeight </code></pre> <p>{</p> <pre><code>CGImageRef imgRef = image.CGImage; CGFloat width = CGImageGetWidth(imgRef); CGFloat height = CGImageGetHeight(imgRef); if (width &lt;= maxWidth &amp;&amp; height &lt;= maxHeight) { return image; } CGAffineTransform transform = CGAffineTransformIdentity; CGRect bounds = CGRectMake(0, 0, width, height); if (width &gt; maxWidth || height &gt; maxHeight) { CGFloat ratio = width/height; if (ratio &gt; 1) { bounds.size.width = maxWidth; bounds.size.height = bounds.size.width / ratio; } else { bounds.size.height = maxHeight; bounds.size.width = bounds.size.height * ratio; } } CGFloat scaleRatio = bounds.size.width / width; UIGraphicsBeginImageContext(bounds.size); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextScaleCTM(context, scaleRatio, -scaleRatio); CGContextTranslateCTM(context, 0, -height); CGContextConcatCTM(context, transform); CGContextDrawImage(UIGraphicsGetCurrentContext(), CGRectMake(0, 0, width, height), imgRef); UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return imageCopy; } </code></pre> <p>Why are ONLY some of my images getting corrupt? Would I need to take a new path and do it a different way? </p> <p>Thanks,<br>Coulton</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.
