Change NSTextField's height according to Font/Size

Ok, here's my situation :

• I've got an NSTextField, set up as Multi-line Text Label
• The NSTextField is supposed to be holding just ONE line of text (even if it's a multi-line one)
• The NSTextField has a fixed height.
• The Font and Font Size are changed by the user

The issue :

• Depending on the font used, and size, the bottom part of the text goes missing (as it goes beyond the NSTextField's boundaries

What I want :

• Get the Text height, based on selection (Font & Font Size) and set the NSTextField's height accordingly.

I know it may sound complicated, but I also know it CAN be done.

Any ideas? Any reference to point me to?

You can take the size of the string and then change the height accordingly

NSString *text = // your string
CGSize constraint = CGSizeMake(210, 20000.0f);
CGSize size = [text sizeWithFont:[UIFont fontWithName:@"Helvetica-Light" size:14] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

UITextField *cellTextLabel = [[UITextField alloc] initWithFrame:CGRectMake(70, 9, 230, size.height)];
cellTextLabel.lineBreakMode = UILineBreakModeWordWrap;
cellTextLabel.numberOfLines = 50;
cellTextLabel.backgroundColor = [UIColor clearColor];
cellTextLabel.text = text;
cellTextLabel.font = [UIFont fontWithName:@"HelveticaNeue-Light" size:14];
[self.view addSubview:cellTextLabel];
[cellTextLabel release];
