How to make UITableviewCell (custom) height is depends on the contents? - ios

Question

In my UIViewController I have a UITableView with custom cell.
Please check below image for screenshot.
In that I am giving "multi line " feature to UILabel (The selected label in screenshot) but I have 2 problems now.
When I open this viewcontroller I can see lots of blank space if my UILabel (Description label) have very small text. How can I manage these white spaces?
Please check the app screenshots
My code
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"cell";
InfoCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[InfoCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:MyIdentifier];
}
cell.header.text=[names objectAtIndex:indexPath.row];
cell.details.text=[details objectAtIndex:indexPath.row];
[cell.header sizeToFit];
[cell.details sizeToFit];
return cell;
}
Please help to clear these issues

Answer 1

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellText = #“Your text”;
UIFont *cellFont = [UIFont systemFontOfSize:YourFontSize];
CGSize constraintSize = CGSizeMake(TextviewWidth, MAXFLOAT);
CGSize labelSize = [cellText sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:NSLineBreakByWordWrapping];
NSLog(#"labelSize : %f", labelSize.height);
return labelSize.height;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #“CustomCell”;
CommentCell *cell = (CommentCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
NSString *cellText = #“LabelText”;
UIFont *cellFont = [UIFont systemFontOfSize:yourFontSize];
CGSize constraintSize = CGSizeMake(LabelWidth, MAXFLOAT);
CGSize labelSize = [cellText sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:NSLineBreakByWordWrapping];
cell.lbl.frame = CGRectMake(cell.lbl.frame.origin.x, cell.lbl.frame.origin.y, cell.lbl.frame.size.width, labelSize.height);
cell.lbl.lineBreakMode = NSLineBreakByWordWrapping;
}

Answer 2

This work for me.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *strYourText = #"Testing Case ";
NSMutableParagraphStyle *objPS = [[NSMutableParagraphStyle alloc] init];
objPS.lineBreakMode=NSLineBreakByWordWrapping;//here you have to pass the Line break mode which you have to label
CGSize labelSize = CGSizeMake(200.0, 1000.0);///width: label width and set the height 1000.0
CGSize textSizeForLabel = [strYourText boundingRectWithSize:labelSize options:NSStringDrawingUsesLineFragmentOrigin attributes:#{NSParagraphStyleAttributeName : objPS,NSFontAttributeName : [UIFont systemFontOfSize:18.0]} context:nil].size;
float labelHeight =ceilf(textSizeForLabel.height);//this are the only lable height.if there are other UIControls then add their heights and retuns.
//Like if One More Buttons is there in cell then return the button height with dynamic lable height (e.g. return labelHeight+buttonHeight );
//herer we are consider there is a only one label is there so return label height
return labelHeight;
