can i seeth e code then abe i can fighure something out

can i see the basic code then maybe i can see somthing out ps my sisters got to the answers above sorry :{}

haydensteed

So this is the coding i needed to upload the images to the backend

pragma mark - Helper methods

• (void)uploadMessage { NSData *fileData; NSString *fileName; NSString *fileType;

  if (self.image != nil) { UIImage *newImage = [self resizeImage:self.image toWidth:320.0f andHeight:480.0f]; fileData = UIImagePNGRepresentation(newImage); fileName = @"image.png"; fileType = @"image"; } else { fileData = [NSData dataWithContentsOfFile:self.videoFilePath]; fileName = @"video.mov"; fileType = @"video"; }

  PFFile *file = [PFFile fileWithName:fileName data:fileData]; [file saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) { if (error) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"An error occurred!" message:@"Please try sending your message again." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; } else { PFObject *message = [PFObject objectWithClassName:@"Messages"]; [message setObject:file forKey:@"file"]; [message setObject:fileType forKey:@"fileType"]; [message setObject:self.recipients forKey:@"recipientIds"]; [message setObject:[[PFUser currentUser] objectId] forKey:@"senderId"]; [message setObject:[[PFUser currentUser] username] forKey:@"senderName"]; [message saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) { if (error) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"An error occurred!" message:@"Please try sending your message again." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alertView show]; } else { // Everything was successful! [self reset]; } }]; } }]; }

• (void)reset { self.image = nil; self.videoFilePath = nil; [self.recipients removeAllObjects]; }

• (UIImage *)resizeImage:(UIImage *)image toWidth:(float)width andHeight:(float)height { CGSize newSize = CGSizeMake(width, height); CGRect newRectangle = CGRectMake(0, 0, width, height); UIGraphicsBeginImageContext(newSize); [self.image drawInRect:newRectangle]; UIImage *resizedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

  return resizedImage; }

@end

And this is for displaying the images

• (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 1; }

• (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. return [self.messages count]; }

• (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

  PFObject *message = [self.messages objectAtIndex:indexPath.row]; cell.textLabel.text = [message objectForKey:@"senderName"];

  NSString *fileType = [message objectForKey:@"fileType"]; if ([fileType isEqualToString:@"image"]) { cell.imageView.image = [UIImage imageNamed:@"icon_image"]; } else { cell.imageView.image = [UIImage imageNamed:@"icon_video"]; }

  return cell; }

pragma mark - Table view delegate

• (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { self.selectedMessage = [self.messages objectAtIndex:indexPath.row]; NSString *fileType = [self.selectedMessage objectForKey:@"fileType"]; if ([fileType isEqualToString:@"image"]) { [self performSegueWithIdentifier:@"showImage" sender:self]; } else { // File type is video PFFile *videoFile = [self.selectedMessage objectForKey:@"file"]; NSURL *fileUrl = [NSURL URLWithString:videoFile.url]; self.moviePlayer.contentURL = fileUrl; [self.moviePlayer prepareToPlay]; [self.moviePlayer thumbnailImageAtTime:0 timeOption:MPMovieTimeOptionNearestKeyFrame];

  // Add it to the view controller so we can see it
  [self.view addSubview:self.moviePlayer.view];
  [self.moviePlayer setFullscreen:YES animated:YES];
  

  }

  // Delete it! NSMutableArray *recipientIds = [NSMutableArray arrayWithArray:[self.selectedMessage objectForKey:@"recipientIds"]]; NSLog(@"Recipients: %@", recipientIds);

  if ([recipientIds count] == 1) { // Last recipient - delete! [self.selectedMessage deleteInBackground]; } else { // Remove the recipient and save [recipientIds removeObject:[[PFUser currentUser] objectId]]; [self.selectedMessage setObject:recipientIds forKey:@"recipientIds"]; [self.selectedMessage saveInBackground]; }

}

Thanks :)
