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.
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];
}
}];
}
}];
