I'm try to emulated something just like the "new message" page in Apple's mail app on the iphone. I've implemented it with a tableview and I've successfully gotten the "To", "CC", and "Subject" rows to behave correctly, but I'm not sure how to implement the actual message portion of the page.
There are several issues that I'm having. I'm currently trying to implement it by placing a UITextView in the cell (I turn off the scroll bars on the text view). I have the text view resize itself when it is changed, by modifying its frame to the new height of the content. The first problem is that I also need to do this for the cell height itself. Since heightForRowAtIndexPath seems to only get called when the row is first loaded, I can't modify the height there. I suppose I could call reload data on the table but this seems like it would be really inefficient to do on the whole table every time text is entered. What is the best way to get the table cell to autoresize as the user types? I've found lots of examples on how to do it on lone table views and how to resize table cells at initialization but I can't find any that let you do both at the same time.
Finally, I would like the bottom border of the table cell to be invisible. If you look at the mail app, you'll notice there is no line at the bottom of the message space, implying that you can just keep typing. I always have one in my table view (even when I add a footer) and I can't figure out how to get rid of it. (Perhaps should I make my message body be the footer itself?)
