title: Memory usage of MKMapView is very high
body: <p>So i have a UIScrollView with UIPageControl which has a bunch of MKMapViews (mostly 15 different maps). The app is really sluggish once this view loads and after a few minutes of usage i get a memory warning. I looked at it in Instruments and the maps take an insanely high chunk of memory. Even upto ~200mb sometimes. One thing i can think of is to reuse the mapViews. But because of how the views are structured the coding complexity increases. Any suggestions how i can improve performance? </p>
  
  <p>This is how my app is structured:</p>
  
  <p>I have a view controller which has a UIScrollView which i use for horizontal scrolling. In the scrollView i read subviews from an array of view controllers which contains the mkmapview. </p>
  
  <p>Hope that made sense! I used Apple's pageControl sample app as a point of reference while coding so the design is roughly similar. </p>
  
  <p>Thanks in advance!</p>
  
  <p><strong>EDIT:</strong> So i tried adding a single instance of the mapView and changing the coordinates on swiping. It still takes a decent amount of memory. </p>
