iOS Question

sizewithattributes not returning correct size

I am tring to calculate the height of text labels in uitableview cells. After seeing that sizewithfont was deprecated with ios 7, I implemented sizewithattributes but the return values were way smaller than what it should be for the label to be of correct size for the text it contains. I also tried the sizetofit method also to no avail.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSDictionary *message = self.messages[indexPath.row];

UILabel *nameLabel = (UILabel *)[cell.contentView viewWithTag:1];
UILabel *messageContent = (UILabel *)[cell.contentView viewWithTag:3];
UIImageView *image = (UIImageView *)[cell.contentView viewWithTag:2];
messageContent.text = [message objectForKey:@"messageContent"];
NSString *content = [message objectForKey:@"messageContent"];
NSLog(@"Message: %@", content);

CGSize textSize = [content sizeWithAttributes:@{ NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Light" size:17.0]}];
messageContent.font = [UIFont fontWithName:@"HelveticaNue-Light" size:17.0];
CGRect messageFrame = messageContent.frame;
messageFrame.size = textSize;
messageContent.frame = messageFrame;

nameLabel.text = [message objectForKey:@"senderName"];
NSString *senderPicture = [message objectForKey:@"senderPicture"];
UIImage* myImage = [UIImage imageWithData:
[NSData dataWithContentsOfURL:
[NSURL URLWithString: senderPicture]]];

image.image = myImage;
image.layer.cornerRadius = 27.0;
image.layer.masksToBounds = YES;

//Configure the cell...

return cell;

well you can try this :

NSDictionary *attributes = @{NSFontAttributeName: [UIFont fontWithName:@"HelveticaNeue" size:14.0f]};
// NSString class method: boundingRectWithSize:options:attributes:context is
// available only on ios7.0 sdk.
CGRect rect = [textToMeasure boundingRectWithSize:CGSizeMake(width, MAXFLOAT)
