What is your end goal for the information you seek?

The method you are using only calculates the size if the text was on a single line. You need a method that returns the size for a multiline layout.

I've had some recent good luck with the sizeWithFont:constrainedToSize:lineBreakMode: method. This may be useful for you but it depends on your end goal. Tip: I set the height for the constrainedToSize value greater than I expect to be using.

You seem to be saying that you do not have the font information. The font information you are using is the txt.font property. So I don't know why you would be saying you don't have the information.

Here is a sample using the above method:

UIFont * myfont = [UIFont systemFontOfSize: 24.0];
NSString mystring = @"Some long string.";
CGSize aBoundingBox = {125, 500}; // Height greater than expected
CGSize boundingSize = [mystring sizeWithFont: myfont constrainedToSize: aBoundingBox lineBreakMode: NSLineBreakByWordWrapping];

if your on iOS6 then UITextView conforms to UITextInputProtocol. One of the required methods of the protocol is

- (NSArray *)selectionRectsForRange:(UITextRange *)range

.

IS that the sort of information your looking for?
