    <p>I have a UIButton that needs to change its image once the user has selected a photo from the photo album to show its selection, I have this setup up and running but once the user has selected a photo I need to resize it to the button dimensions and that is where I need help, here is my code:</p> <pre><code>-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [picker dismissModalViewControllerAnimated:YES]; UIImage *giftImage = [info objectForKey:UIImagePickerControllerOriginalImage]; [giftImage resizableImageWithCapInsets:UIEdgeInsetsMake( 0, 10, 0, 10 )]; [giftButton setBackgroundImage:giftImage forState:UIControlStateNormal]; giftButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentFill; giftButton.imageView.contentMode = UIViewContentModeScaleToFill; giftButton.imageView.bounds = CGRectMake( 0, 0, 62, 62 ); } </code></pre> <p>UPDATE: Found a solution, so far all that happen was that the button got resized to the image dimensions, but using the following code, I manage to insert the image inside at the size I need, it is a work in progress but is working ;)</p> <pre><code>CGSize targetSize = CGSizeMake( 62, 62 ); UIGraphicsBeginImageContext( targetSize ); CGRect thumbnailRect = CGRectZero; thumbnailRect.origin = CGPointMake( 0, 0 ); thumbnailRect.size.width = 62; thumbnailRect.size.height = 62; [giftImage drawInRect:thumbnailRect]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); [giftButton setBackgroundImage:newImage forState:UIControlStateNormal]; UIGraphicsEndImageContext(); </code></pre> <p>The code is from this post <a href="https://stackoverflow.com/questions/1367384/resize-and-crop-images-before-displaying-in-uitableviewcells">Resize and crop images before displaying in UITableViewCells</a></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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
