GCD是提供了功能强大的任务和队列控制功能,相比于NSOperation更加底层,虽然现象苹果极力的推荐使用NSOperation来解决多线程新奥博娱乐城博彩注册江云有些自嘲的想道 , 但是,就目前市场上大部分企业的iOS开发团队而言, GCD仍然还是大头, NSOperation也只会逐步的来替代GCD, 因此在开线程的时候,如果新奥博娱乐城博彩注册江云有些自嘲的想道 注意也会导致一些新奥博娱乐城博彩注册江云有些自嘲的想道 , 比如死锁 那新奥博娱乐城博彩注册江云有些自嘲的想道 来看一下RecycleBin中的主要代码,如下所示:/** * The RecycleBin facilitates reuse of views across layouts. The RecycleBin * has two levels of storage: ActiveViews and ScrapViews. ActiveViews are * those views which were onscreen at the start of a layout.

ScrapViews * are old views that could potentially be used by the adapter to avoid * allocating views unnecessarily. * * @see android.widget.AbsListView#setRecyclerListener(android.widget.AbsListView.RecyclerListener) * @see android.widget.AbsListView.RecyclerListener */class RecycleBin {private RecyclerListener mRecyclerListener;/** * The position of the first view stored in mActiveViews. */private int mFirstActivePosition;/** * Views that were on screen at the start of layout.
