Calling delegate method UICollectionViewCell - ios

Question

I'm having trouble calling a delegate method that resides in my UICollectionViewCell...
In my FOFPhotoCell.m i have the following code:
-(void)fadeOutLabels
{
NSLog(#"fadeOutLabels was called");
[UIView animateWithDuration:1.0
delay:0.0 /* do not add a delay because we will use performSelector. */
options:UIViewAnimationOptionCurveEaseIn
animations:^ {
self.titleLabel.alpha = 0.0;
}
completion:^(BOOL finished) {
[self.titleLabel removeFromSuperview];
}];
}
in the FOFPhotoCell.h there is the following defined:
#protocol FOFPhotoCellDelegate <NSObject>
#required
-(void)fadeOutLabels;
#end
#interface FOFPhotoCell : UICollectionViewCell {
id delegate;
}
#property (nonatomic, weak) id<FOFPhotoCellDelegate> delegate;
in my FOFPhotosViewController.h:
#interface FOFPhotosViewController : UICollectionViewController <FOFPhotoCellDelegate>
#end
and lastly, my FOFPhotosViewController.m:
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
FOFPhotoCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"photo" forIndexPath:indexPath];
NSArray *photosArray = [self.dishes valueForKeyPath:#"avatar_url"];
NSArray *nameArray = [self.dishes valueForKeyPath:#"name"];
// NSLog(#"photoURL %#", _responseDictionary);
cell.backgroundColor = [UIColor lightGrayColor];
[cell.imageView setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"****",[photosArray objectAtIndex: indexPath.row]]]];
cell.titleLabel.text = [NSString stringWithFormat:#"%#", [nameArray objectAtIndex:indexPath.row]];
UILongPressGestureRecognizer *tapAndHold = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:#selector(fadeOutLabels)];
tapAndHold.minimumPressDuration = 0.5;
[self.collectionView addGestureRecognizer:tapAndHold];
[self.collectionView reloadItemsAtIndexPaths:[NSArray arrayWithObject:indexPath]];
return cell;
}
But this makes the app crash: -[FOFPhotosViewController fadeOutLabels]: unrecognized selector sent to instance
I can't seem to figure this one out, so I would really appreciate some help! Let me know if any more code is needed.
Thanks in advance

Answer 1

fadeOutLables is a method of your cell, not of your view controller.
The error message is just right.
Assuming that everything else is right, change this line as follows:
UILongPressGestureRecognizer *tapAndHold = [[UILongPressGestureRecognizer alloc] initWithTarget:cell action:#selector(fadeOutLabels)];
