당신이 scorllView에있는 UIImageView에 필요한 것

- (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]; 
}
