Hi,
I want to implement a in-app chat view like the following pic. http://img408.imageshack.us/img408/4057/img0139.png
How can I implement the input bar? As I cannot found any resourece on internet.
Thanks.
Best,
Dante
A:
Use a UITextView, check for new line character in textViewDidBeginEditing and increase the height of the text view (and the background view if you have one).

but how can I make a toolbar like that one in the pic that autoresize to the height of the textview? Thanks

Add a UIView/UIImageView behind the text view and resize it when you resize the text view. I don't think the bar in the picture is a standard iPhone toolbar.

I can increase the height when the user press return but how can I reduce the height by deleting line?

A:
Don't count newline chars, since you will miss lines added by long sentences, but use NSString's sizeWithFont methods. See http://stackoverflow.com/questions/406226/documentation-for-nsstring-sizewithfontforwidthlinebreakmode-method-in-the-ip
Then resize all elements appropriately (no, this will not happen by itself, you have to do it).
