Changing Text Color of UICollectionViewCell on selection programmatically

Have to overwrite the setSelected method of UICollectionView Class. Don't forget to call super as well. 

-(void)setSelected:(BOOL)selected{

    [super setSelected:selected];

    if (selected) {

       self.tagLabel.textColor=[UIColor blackColor];

    }

    else

        

     self.tagLabel.textColor=[UIColor lightTextColor];

    

}
