iOS custom UITableViewCell set UIButton title label text - cocoa-touch

Question

I am making a chatting application.
In my datasource method, I dequeue a cell and pass a Core Data Entity to initialize it.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
Post *post = self.posts[indexPath.row];
AbstractPostCell *cell;
if ([post.type isEqualToString:#"text"]) {
cell = [tableView dequeueReusableCellWithIdentifier:CELL_POST_LIST_TEXT forIndexPath:indexPath];
}
else if ([post.type isEqualToString:#"image"]) {
cell = [tableView dequeueReusableCellWithIdentifier:CELL_POST_LIST_IMAGE forIndexPath:indexPath];
}
[cell setupWithPost:post];
return cell;
}
Here is setupWithPost method:
- (void)setupWithPost:(Post *)post {
self.label.text = post.text;
self.datetimeLabel.text = [Format stringWithDatetime:post.datetime];
if ([DBHelper didLikePost:post likerID:[Helper currentUserID]]) {
self.likeButton.enabled = NO;
self.likeButton.titleLabel.alpha = 0.5;
self.likeButton.titleLabel.text = [NSString stringWithFormat:#"liked"];
}
else {
self.likeButton.enabled = YES;
self.likeButton.titleLabel.alpha = 1.0;
self.likeButton.titleLabel.text = [NSString stringWithFormat:#"like"];
}
}
the button labels are correct when I first enter the ListViewController(TableViewController), but When I navigate to the next ViewController (DetailViewController), and then navigate back, all button labels become unset (showing whatever text I preset in storyboard)
Interestingly, when I scroll down and then scroll back, all the buttons labels become correct again.
I have tried prepareForReuse but not working
NOTE: this applies only to button title labels, normal labels (e.g. datetimeLabel) are always correctly displayed
- (void)prepareForReuse {
[super prepareForReuse];
self.label.text = #"";
self.datetimeLabel.text = #"";
self.likeButton.titleLabel.text = #"";
}

that sound very strange, I don't know if this is the cause of the problem but you should set a button title using the API
- (void)setTitle:(NSString *)title forState:(UIControlState)state
try
[self.likeButton setTitle:#"some title" forState:UIControlStateNormal];
