如何保持uiview的视野

Question

i have a view that is required to be stayed on the view when the user scroll up or down in a scrollview.

i managed to let it stay on top of the view but how can i allow it to stay at the bottom of the view when i scroll down ? EDIT: attached picture to explain better.

the view will alway be visible on the view.

-(void) scrollViewDidScroll:(UIScrollView *)scrollView
{
    NSLog (@"Content Offset: %f", self.playlistTableview.contentOffset.y);

    if (self.playlistTableview.contentOffset.y > playerPosition) // will keep the view at the top
    {
        CGRect newFrame = self.playerView.frame;
        newFrame.origin.x = 0;
        newFrame.origin.y = +self.playlistTableview.contentOffset.y;
        [self.playerView  setFrame: newFrame];
    }
}

you can see how the NZD have a top overlay that stops

Answer 1

Try to add your ScrollView and Always Stay view in a container view. So it will not scroll when you do scroll the scroll view. and anytime you can change your always stay view to different frame to top or bottom as u needed

UIView--->
      1st subview--->UIScrollView
      2nd subview--->Don't ScrollMeView/Always Stay view                

Answer 2

I think you have added your view in contain of UIScrollView.

I mean, main container for your view is UIScrollview, so it'll work as subview of UIScrollview and will follow scrollview properties. Can you please try to add your view on main view.

[self.view addSubView:yourViewObj];

If that comes behind the scrollView, then please try with

[self.view bringSubviewToFront:yourViewObj];
