UILabel inside of UIScrollView tutorial for iOS developers

It seems like you'd actually want to use UITextView for this instead of UILabel, especially if you want more interesting things like touchable URLs within the text.

But I must admit to never trying that in an iOS project; I'm basing this on what the Mac's NSTextView is capable of.

Add a timer with scrollRectToVisible and you've got an iTunes marquee going.

your code comments are mostly unnecessary. a 'label.text = "my text";' is pretty much self explanatory and doesn't need a comment that you assign 'my text' to a label.
