Question

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString * message =[[chatData objectAtIndex:indexPath.row]valueForKey:#"message"];
NSString * message_type = [[chatData objectAtIndex:indexPath.row]valueForKey:#"message_type"];

CGSize sizeText = [self text:message sizeWithFont:[UIFont systemFontOfSize:16] constrainedToSize:CGSizeMake(CGRectGetWidth([UIScreen mainScreen].bounds) - 100, 9999) withLinebreakmode:NSLineBreakByWordWrapping];
CGFloat heightOfRow = sizeText.height + 2 * 7.5f;
return heightOfRow + 50;
}
else
return 225;//message_type 1 3 4
// return self.chatTable.rowHeight;
}

Try this code.
1.if you use this code,you should give only top,bottom,left and right constraint for label.
-(CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {
//Here you give a minimum height of the cell size.
return 110;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return UITableViewAutomaticDimension;
}
