How to enable scrolling for UITextView when building software

I created a UITextView programmatically and want to enable scrolling for this UITextView.

Is there any property or method for doing this because it is not enabled by default. I am using the following code which displays it but does not scroll to the bottom.

UITextView* txt_tipView = [[UITextView alloc] initWithFrame:CGRectMake(0, 0, 165, 60)];
        txt_tipView.backgroundColor = [UIColor clearColor];
        txt_tipView.textColor = [UIColor colorWithRed:(51/255) green:(51/255) blue:(51/255) alpha:1];

        txt_tipView.font = [UIFont fontWithName:@"Helvetica" size:12];//[UIFont boldSystemFontOfSize:12];
        txt_tipView.editable = FALSE;

        txt_tipView.frame = CGRectMake(138, 96, 165, 60);
        [self.view addSubview:txt_tipView];

UITextView inherits UIScrollView (you can see this in the Inspector tab in Interface Builder or through the documentation). This means that any property of the UIScrollView can also be set on the UITextView:



txt_tipView.scrollEnabled = YES;
