AFAIK there's no *simple* way to do it perfectly. You can use [NSString sizeWithAttributes:] to determine the height but you'll need to match the text field's attributes as nearly as you can figure out. Even then, there will be edge cases where you're off by one line, because text fields use compatibility modes of the text subsystem, which can affect line breaks. If you want to get into this a bit deeper, Jerry Krinock has attempted to unravel the mystery here: http://www.sheepsystems.com/sourceCode/sourceStringGeometrics.html > - How do (or can) I set up constraints so that the window and other controls > will accommodate that change? Moving other controls should be straightforward -- add constraints for what's above the text field to the top of the text field, and what's below to the bottom. You should be able to constrain view heights to the positions of their contents, but it will take a bit of mucking around with fixed, minimum and maximum sizes/positions, not to mention priorities. (Listening to the 2nd half of the WWDC session on this should be helpful.) I don't know offhand if resizing the content view via layout will cause the window to resize too. OTOH, it may not be worth going to all this trouble. If you've calculated the desired text field height, it might be easier just to resize the window yourself. If you do it that way, you can get the added height to trickle down to (eventually) the text field itself, rather than changing the text field and trying to get the difference to bubble up to the window. Also, keep in mind that layout in Xcode is not quire ready for prime time, even in 4.2. Don't be surprised if Xcode crashes a lot once you start adding manual constraints.
