Some time ago I’ve found the following Code on the Internet and it works very well:

- (float) calculateHeightOfTextFromWidth:(NSString*) text: (UIFont*)withFont: (float)width :(UILineBreakMode)lineBreakMode
{

    [text retain];
    [withFont retain];
    CGSize suggestedSize = [text sizeWithFont:withFont constrainedToSize:CGSizeMake(width, 1000.0) lineBreakMode:lineBreakMode];

    [text release];
    [withFont release];
    NSLog(@"%f", suggestedSize.height);
    return suggestedSize.height;

}

I use this in my own app like this:

scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, [self calculateHeightOfTextFromWidth:thetext :[UIFont fontWithName:@"Helvetica" size:17.0] :320 :UILineBreakModeWordWrap]);
