Warning inside code when updating Parse object - ios

Question

I am using the following code to update a Parse object as button action:
-(IBAction)sendPressed:(id)sender
{
NSLog(#"boton subir cadena pulsado");
loadingSpinner.hidden = NO;
[loadingSpinner startAnimating];
//Upload a new picture
NSData *pictureData = UIImagePNGRepresentation(self.chainPhoto.image);
PFFile *file = [PFFile fileWithName:#"img" data:pictureData];
[file saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (succeeded){
NSLog(#"IMAGEN CARGADA");
PFQuery *query = [PFQuery queryWithClassName:#"cadenas"];
// Retrieve the object by id
[query getObjectInBackgroundWithId: chain.objectId block:^(PFObject *imageObject, NSError *error)
{
[imageObject setObject:file forKey:#"image"];
[imageObject setObject:self.commentTextField.text forKey:#"chain_name"];
[imageObject saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (succeeded){
//Go back to the wall
[self.navigationController popViewControllerAnimated:YES];
}
else{
NSString *errorString = [[error userInfo] objectForKey:#"error"];
[self showErrorView:errorString];
}
}];
}
ERROR HERE--> else
{
NSString *errorString = [[error userInfo] objectForKey:#"error"];
[self showErrorView:errorString];
}
}
[loadingSpinner stopAnimating];
//loadingSpinner.hidden = YES;
//self.commentTextField.text =#" ";
self.progress_block.hidden = YES;
// self.imageView.image = [UIImage imageNamed:#"no-image.jpg"];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Restaurant Chain changed with success"
message:#"You can now go back to the list."
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
} progressBlock:^(int percentDone) {
self.progress_block.hidden =NO;
self.progress_block.progress = (float) percentDone/100+progressValue;
}];
}
In the line that I have marked as ERROR HERE in the code, there is an error warning (Expected ":"), but I can't find out why.
Any help is welcome.

From the looks of it, you never closed the query bracket:
PFQuery getObjectInBackground.... {
but never closed it using the proper syntax or it looks like you have an extra bracket }. For better practice, you should use proper indentation with if statements or else complications can happen like this. You get lost in the code because you don't know where a statement begins or ends
You should close it after the else statement so:
} ERROR HERE--> else {
NSString *errorString = [[error userInfo] objectForKey:#"error"];
[self showErrorView:errorString];
//stop animating and other stuff
}
}];
I can't troubleshoot because i'm on my iPhone but I would suggest going back and using proper indentation so you can catch your culprit
