Retrieving image from parse.com

image, ios, iphone, parsing

Solution

Yes, this is possible. If you use web interface to instead of string you should specify PFFile as a type. If you upload image from your iOS client here is a link to parse iOS guide how to do that https://parse.com/docs/ios_guide#files/iOS . Once your image is there you can download image this way:

PFQuery *query = [PFQuery queryWithClassName:@"app"];
[query getObjectInBackgroundWithId:@"ID"
                         block:^(PFObject *textdu, NSError *error) {
{
     // do your thing with text 
     if (!error) {
          PFFile *imageFile = [textdu objectForKey:@"image"];
          [imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
              if (!error) {
                  UIImage *image = [UIImage imageWithData:data];
              }
          }];
     }
 }];

Problem

I don't know if this is possible but I think it could be possible and I dont know how to do this. I simply want to load an image from parse.com like you retrieve objects from parse.com. Should I do it the same way I get strings from parse.com? I just found how to save images on parse but not how to get them. I would be happy if someone could show me a link to do this or a sample code. I've already set up a string which is retrieved from parse: ``` PFQuery *query = [PFQuery queryWithClassName:@"app"]; [query getObjectInBackgroundWithId:@"ID" block:^(PFObject *textdu, NSError *error) { if (!error) { UIFont *welcomeLabelFont = [UIFont boldSystemFontOfSize:17]; welcomeLabel.text = [textdu objectForKey:@"ueberschriftnews"]; welcomeLabel.font = welcomeLabelFont; welcomeLabel.textColor = [UIColor whiteColor]; welcomeLabel.textAlignment = NSTextAlignmentCenter; welcomeLabel.backgroundColor = [UIColor clearColor]; welcomeLabel.shadowColor = [UIColor blackColor]; welcomeLabel.shadowOffset = CGSizeMake(0, 1); [contentView addSubview:welcomeLabel]; // The get request succeeded. Log the score NSString *text = [textdu objectForKey:@"newstext"]; UIFont *font = nil; CGFloat points = 17; CGFloat maxHeight = infoLabel.frame.size.height; CGFloat textHeight; do { font = [UIFont systemFontOfSize:points]; CGSize size = CGSizeMake(infoLabelRect.size.width, 100000); CGSize textSize = [text sizeWithFont:font constrainedToSize:size lineBreakMode: NSLineBreakByWordWrapping]; textHeight = textSize.height; points -= 1; } while (textHeight > maxHeight); infoLabel.text = text; infoLabel.numberOfLines = 9; infoLabel.font = font; infoLabel.textColor = [UIColor whiteColor]; infoLabel.textAlignment = NSTextAlignmentCenter; infoLabel.backgroundColor = [UIColor clearColor]; infoLabel.shadowColor = [UIColor blackColor]; infoLabel.shadowOffset = CGSizeMake(0, 1); [infoLabel sizeToFit]; [contentView addSubview:infoLabel]; } else { infoLabel.text = @"something"; [infoLabel sizeToFit]; [contentView addSubview:infoLabel]; } }]; ``` My parse set up: Thanks.
