can you post your code

this is my code

import "imageViewViewController.h"

@interface imageViewViewController ()

@end

@implementation imageViewViewController

• (void)viewDidLoad { [super viewDidLoad];

//
PFFile *imageFile = [self.message objectForKey:@"file"]; NSURL *imageFileUrl = [[NSURL alloc] initWithString:imageFile.url]; NSData *imageData = [NSData dataWithContentsOfURL:imageFileUrl]; self.imageView.image = [UIImage imageWithData:imageData];

//

}

@end

ok add the following logs to your code to see if your message object actually holds data

 PFFile *imageFile = [self.message objectForKey:@"file"];

NSLog(@"imageFile: %@", imageFile);
NSLog(@"imageFileURL: %@", imageFile.url);

    NSURL *imageFileUrl = [[NSURL alloc] initWithString:imageFile.url];
    NSData *imageData = [NSData dataWithContentsOfURL:imageFileUrl];
    self.imageView.image = [UIImage imageWithData:imageData];

post what comes back in the console. if its nil you have a problem with your message being saved (maybe the url isnt being saved or something)

am getting this

imageFile: (null) 2014-07-20 23:15:39.144 Ribbit[6390:60b] imageFileURL: (null) 2014-07-20 23:15:39.355 Ribbit[6390:60b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initWithString:relativeToURL:]: nil string parameter'

looks like i don't have an image

ok so your image is null. you can do the same style of logs where ever you upload the message. find in your code where you upload the message, and log the file attribute of your message object just before it gets uploaded to parse. if it comes back null something is wrong with your code where you upload the file
