Issue with User Photo (Profile Picture) with parse - ios

Question

I have some issues with user photos (profile pictures). For every time a single user update his profile picture, it also updates the rest of the users with the same image. How do I change it so it doesn't change everywhere? I am using parse.com
I'm using following codes.
Uploading the photo:
- (void)uploadProfilePhoto {
NSData *imageData;
NSString *imageName;
NSString *imageType;
//Shrink it
//Upload profile photo
(self.image != nil); {
UIImage *resizeImage = [self resizeImage:self.image toWidth:320.0f andHeight:320.0f];
imageData = UIImagePNGRepresentation(resizeImage);
imageName = #"profileimage.png";
imageType = #"image";
}
PFFile *image = [PFFile fileWithName:imageName data:imageData];
[image saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Something went wrong!" message:#"Please try again." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
else {
PFObject *UserPhotos = [PFObject objectWithClassName:#"UserPhoto"];
[UserPhotos setObject:image forKey:#"image"];
[UserPhotos setObject:imageType forKey:#"imageType"];
[UserPhotos setObject:[PFUser currentUser] forKey:#"user"];
[UserPhotos setObject:[[PFUser currentUser] objectId] forKey:#"uploaderId"];
[UserPhotos setObject:[[PFUser currentUser] username] forKey:#"uploaderUsername"];
[UserPhotos saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Something went wrong!" message:#"Please try uploading your photo again." delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
}
else {
//Everything was successfull!
}
}];
}
}];
}
When I retrieve the photo:
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
PFQuery *query = [PFQuery queryWithClassName:#"UserPhoto"];
[query includeKey:#"user"];
[query orderByDescending:#"createdAt"];
[query getFirstObjectInBackgroundWithBlock:^(PFObject *object, NSError *error) {
if (!object) {
return NSLog(#"%#", error);
}
PFFile *imageFile = object[#"image"];
[imageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!data) {
return NSLog(#"%#", error);
}
// Do something with the image
self.profileImage.image = [UIImage imageWithData:data];
}];
}];
[self.navigationController.navigationBar setHidden:YES];
}
Thanks!
