问题:

It's possible to put a button inside a scroll view and make it scroll together with the view?

I try to explain the issue. I have a scrollView containing a textView showing some text. In the text there's a link and i have a button, put beside this link that, when pressed, open the link in safari. Now, the text is longer than the textView, so i had to put the Text view inside a Scroll View to make it scroll. I tried putting the button inside the scrollView as well, but when i scroll, only the text get scrolled and the button stays still where it is, when instead i want the button to scroll together with the text, to have it evere beside the link that is in the text. Is is possible?

As far as I'm aware, you can't put controls inside a UITextView.

You could implement your desired behaviour by moving the button during the textView's - (void)scrollViewDidScroll:(UIScrollView *)scrollView delegate method.

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    // Move button according to scroll position, using scrollView.contentOffset
}
