    <p>I am creating an app where a user can load their schedule into the app, and it is subsequently displayed.</p> <p>When the image is allowed to be edited before loading, it shows up perfectly:</p> <p><img src="https://i.stack.imgur.com/K00U2.png" alt="Image 1"></p> <p>Once the user "chooses" the image, it shows up in the <code>UIImageView</code> blurred:</p> <p><img src="https://i.stack.imgur.com/aR04F.png" alt="Image 2"></p> <p>Here it is slightly zoomed in:</p> <p><img src="https://i.stack.imgur.com/PowfW.png" alt="Image 3"></p> <p>I know that the image resolution is okay because image displays perfectly beforehand. <strong>How can I stop this from being blurred?</strong></p> <p>I am using the basic method of zooming an <code>UIImageView</code> in an <code>UIScrollView</code>.</p> <p>Here is the code I use to assign the image. zoomscroll is the <code>UIScrollView</code> and myschedule is the <code>UIImageView</code>:</p> <pre><code>-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [self dismissModalViewControllerAnimated:YES]; //Obtaining saving path NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *imagePath = [documentsDirectory stringByAppendingPathComponent:@"myschedule.png"]; //Extracting image from the picker and saving it NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; if ([mediaType isEqualToString:@"public.image"]){ UIImage *editedImage = [info objectForKey:UIImagePickerControllerEditedImage]; NSData *webData = UIImagePNGRepresentation(editedImage); [webData writeToFile:imagePath atomically:YES]; myschedule.image = editedImage; [zoomscroll addSubview:myschedule]; zoomscroll.contentSize = CGSizeMake(myschedule.frame.size.width , myschedule.frame.size.height); zoomscroll.minimumZoomScale = 1.0; zoomscroll.maximumZoomScale = 4.0; } } </code></pre> <p>Thank you!</p>

    1. COWhat happens (code) when the user chooses the image? Are you re-setting the image of the image view or changing some property of the image view?

    3. COHave you tried looking at using a PDF viewer instead of an imageView. The problem is the imageview doesn't redraw itself at a higher resolution when you zoom.

Guidance
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).
