使用UITextView作为子视图创建UIScrollView获取触摸事件

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 200)];
scrollView.contentSize = CGSizeMake(self.view.frame.size.width, 200);

UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, scrollView.contentSize.width, scrollView.contentSize.height)];
textView.text = @"Hello, World!";
textView.font = [UIFont systemFontOfSize:14];
textView.textColor = [UIColor blackColor];
textView.editable = NO;
textView.scrollEnabled = NO;
[scrollView addSubview:textView];

scrollView.delegate = self;

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    CGFloat y = scrollView.contentOffset.y;
    CGRect rect = textView.frame;
    rect.origin.y = y;
    textView.frame = rect;
}
