You will needed to the UIImageView to the scorllView.
- (void) setupTextView
{
textDescription.scrollEnabled = NO;
NSString *foo = #"Hello Test";
textDescription.text = foo;
/*Here is something for dynamic textview*/
CGRect frame;
frame = textDescription.frame;
frame.size.height = [textDescription contentSize].height;
textDescription.frame = frame;
/**/
int linePosition = frame.size.height+20;
lineImg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"line.png"]];
CGRect line2Frame = CGRectMake(-8, 600, 328, 10);
lineImg.frame = line2Frame;
//Add the image view as a subview to yout scrollview.
[scrollView addSubView:lineImg];
}
