TTStyledTextLabel inside UITextView - iphone

Question

I have a need to display text that includes HTML tags etc and TTStyledTextLabel fits the bill.....but it does not scroll.
I placed one inside a UITextView but this refuses to scroll? If I enter the text directly in the UITextView it scrolls OK but then I see all the HTML unformatted.
Is there a way to set TTStyledTextLabel to scroll?
Thanks

Answer 1

Try putting the TTStyledTextLabel in a UIScrollView.
Alternately, you can consider using a UIWebView directly.

Answer 2

I finally got a suitable work around...
CGSize constraintSize;
CGSize stringSize;
// make an overly big size allowance
constraintSize.width = 300;
constraintSize.height = 2000;
NSString *s = #"this can be text as long or as short as required...;
UIFont *f = [UIFont fontWithName:#"Arial" size:14];
stringSize =[s sizeWithFont:f constrainedToSize: constraintSize lineBreakMode: UILineBreakModeWordWrap];
// create a label to accomodate the text
UILabel *l = [[UILabel alloc] initWithFrame:CGRectMake(14, 2, stringSize.width, stringSize.height)];
l.text = s;
[l setNumberOfLines:0];
[l sizeToFit];
// now create a TTStyledTextLabel to match the size we just obtained above
TTStyledTextLabel *tl = [[TTStyledTextLabel alloc] initWithFrame:[l frame]];
// set the text making use of links etc
tl.text = [TTStyledText textFromXHTML:l.text lineBreaks:YES URLs:YES];
[tl setBackgroundColor:[UIColor clearColor]];
tl.textColor = [UIColor whiteColor];
UIScrollView *sv = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 185, 320, 300)];
// adjust scrollview content size to accomodate the TTStyledTextLabel
[sv setContentSize:CGSizeMake(tl.frame.size.width, tl.frame.size.height)];
[sv addSubview:tl];
[self.view addSubview:sv];
Now I can have an auto sizing TTStyledTextLabel that scrolls ;-)
