POUIScrollView ImageView with pins on top
text
Body
copied!<p>I have a <code>UIScrollView</code> which has a <code>UIImageView</code>. I want to show pins on this <code>imageView</code>. When I add pins as subviews of the <code>ImageView</code>, everything is great except for when you zoom the scale transform happens on the pins also. I don't want this behavior and want my pins to stay the same.</p> <p>So I choose to add the Pins to another view which sits on top of the ImageView and is also a subview of the <code>UIScrollView</code>. The idea here if you will imagine is to have a layer which hovers over the map and won't scale yet show pins over where I plot them.</p> <p>The pin when added to the layer view don't cale if the <code>ImageView</code> scales. However, the issue then becomes the position of the pins doesn't match the original origin x/y as the <code>ImageView</code> has had a scale transform.</p> <p>Basically this is a custom map of a place with Pins. I am trying to have the Pins float over and not zoom in and out over my ImageView yet remember where I placed them when the zoom happens.</p> <p>Some code:</p> <pre><code>scrollView = [[UIScrollView alloc] initWithFrame:viewRect]; scrollView.delegate = self; scrollView.pagingEnabled = NO; scrollView.scrollsToTop = NO; [scrollView setBackgroundColor:[UIColor clearColor]]; scrollView.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview scrollView.bounces = YES; scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight; scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite; imageViewMap = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; imageViewMap.userInteractionEnabled = YES; viewRect = CGRectMake(0,0,imageViewMap.image.size.width,imageViewMap.image.size.height); //viewRect = CGRectMake(0,0,2976,3928); [scrollView addSubview:imageViewMap]; [scrollView setContentSize:CGSizeMake(viewRect.size.width, viewRect.size.height)]; iconsView = [[UIView alloc] initWithFrame:imageViewMap.frame]; [scrollView addSubview:iconsView]; </code></pre> <p>Code to add Pin later on some event.</p> <pre><code>[iconsView addSubview:pinIcon]; </code></pre> <p>I am stuck in trying tp figure out how to to get my pins to hover on the map without moving when the scale happens.</p>
