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)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributes
context:nil];
Problem
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; } ```
