问题 I have a ViewController in which the user selects a card (a custom UIButton) out of a UIScrollView. I have intercepted the touch event selecting the card and identified it, and then removed it from the data source, but it still exists in the UISubView. How do I get rid of it?

问题 Has anyone else, who's using maps in their iOS 6 apps, noticing extremely high memory use to the point of receiving memory warnings over and over to the point of crashing the app? I've ran the app through instruments and I'm not seeing any leaks and until the map view is created the app consistently runs at around ~3mb Live Bytes.
