UITableView custom cell showing weird results? - iphone

Question

UITableView custom cell showing weird results? I have my code below. Everything was showing fine until I put enough data to go off the initial screen then it started going crazy? My custom cell is shown below.
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"customCell"; // This is identifier given in IB jason set this.
PostTableCustomCellController *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSLog(#"Cell created");
NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:#"PostTableCustomCellController" owner:nil options:nil];
for(id currentObject in nibObjects)
{
if([currentObject isKindOfClass:[PostTableCustomCellController class]])
{
cell = (PostTableCustomCellController *)currentObject;
}
}
}
Post *post = [postsArray objectAtIndex:indexPath.row];
cell.authorName.text = post.author;
cell.deadline.text = post.deadline;
cell.description.text = post.description;
Post *myPost = [postsArray objectAtIndex:[indexPath row]];
NSString *text = myPost.description;
// Configure the cell...
// [[cell authorName] setText:#"1 day"];
// [[cell distance] setText:#"Austin, TX"];
// [[cell description] setText:#"dd" ];
// Might can remove these
UILabel *locationLabel = (UILabel *) [cell distance];
UILabel *postTextView = (UILabel *) [cell description];
//CGSize maximumLabelSize = CGSizeMake(254,88.0f);
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 88.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGFloat height = MAX(size.height, 35.0f);
CGFloat realHeight = height + 36.0f - (10);
CGSize expectedLabelSize = [text sizeWithFont:postTextView.font
constrainedToSize:constraint
lineBreakMode:postTextView.lineBreakMode];
CGRect newFrame = postTextView.frame;
newFrame.size.height = expectedLabelSize.height;
postTextView.frame = newFrame;
[[cell description] sizeToFit];
CGRect locationRect = locationLabel.frame; // calls the getter
locationRect.origin.y = realHeight;
/* CGFloat locRectHeight = postTextView.bounds.size.height; */
/* locationRect.origin.y = cell.bounds.size.height; */
locationLabel.frame = locationRect;
//[[cell authorName] setText:#"jgervin"];
[[cell viewForBackground] sizeToFit];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
{
Post *myPost = [postsArray objectAtIndex:[indexPath row]];
NSString *text = myPost.description;
CGSize constraint = CGSizeMake(CELL_CONTENT_WIDTH - (CELL_CONTENT_MARGIN * 2), 88.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
CGFloat height = MAX(size.height, 35.0f);
return height + (CELL_CONTENT_MARGIN * 2) + 36.0f;
}

Answer 1

You queing up old cells as they go off screen do to your dequeReusableCell, and the content and properties from the old cell must still be there. When you add content to a cell make sure to clear any previous properties so you can avoid these issues, or just turn off dequeReusableCell.

Answer 2

It looks like a cell-reuse problem. Why dont your turn off the dequeue-cell mechanism and see if the problem goes away. If it does, take a look at the code in your custom cell - are you creating multiple copies of the field labels? It looks that way.
