如何在uitableviewcell中创建阴影效果？(How to create shadow effect in uitableviewcell?)

 我正在开发一个应用程序，其中我想创建类似于底部uitableviewcell中下图所示的阴影效果。  
 
 我该怎么做？任何教程或示例代码？ 我检查了http://cocoawithlove.com/2009/04/easy-custom-uitableview-drawing.html，http://www.touchthatfruit.com/?tag=uitableview和其他一些，但他们在底部有阴影与相同高度的uitableview。以及如何在包含日期的每个部分的边框处添加阴影（而不是整个tableview）。我可以在底部创建下拉阴影。但是，每个部分的最后一个uitableview单元格的边框怎么样？一种方法是创建图像并将其设置为tableviewcell的背景。但如何调整图像大小并使其看起来合适，因为每个部分都有动态数量的条目。一个部分只有1个条目，其他部分可能包含15个或更多条目。这里的图像是包含日期的整个部分）.i可以为每个部分的最后一个tableviewcell提供单独的图像。这是我知道的。但是有没有更好的方法或以编程方式进行？ 

i am developing one application in which i want to create shadow effect similar to shown in below image at bottom uitableviewcell. 
 
How can i do that?any tutorial or sample code? I have checked http://cocoawithlove.com/2009/04/easy-custom-uitableview-drawing.html, http://www.touchthatfruit.com/?tag=uitableview and some other ones.but they have shadow at bottom of uitableview with same height.and how to add shadow at side borders of each section containing the date(not the entire tableview).I can create the dropdown shadow at bottom.but what about side borders of last uitableview cell of each section.and one way is creating the image and setting it as background of tableviewcell.But how to resize the image and will it look proper because each section has dynamic number of entries.one section only have 1 entry and other may contain 15 or more entries.(here image is for entire section which contains date).i can have seperate image for only last tableviewcell of each section.This is i know.but is there any better approach or do it programatically?

 找到了许多技巧的方法，适用于任何服务  
 首先运行svr，然后运行cli并测试。  
public class PlayHZ
{
    @Test
    public void test() throws ExecutionException, InterruptedException
    {
        HazelcastInstance hz = Hazelcast.newHazelcastInstance();
        IExecutorService executor = hz.getExecutorService("gather");
        Map<Member, Future<List<String>>> futures = executor.submitToAllMembers(new LockNameGather());
        Thread.sleep(1000);
        System.out.println("Found in member");
        for (Map.Entry<Member, Future<List<String>>> entry : futures.entrySet())
        {
            System.out.printf("%s -> %s\n", entry.getKey(), entry.getValue().get());
        }
    }

    @Test
    public void svr() throws InterruptedException
    {
        HazelcastInstance hz = Hazelcast.newHazelcastInstance();
        Thread.sleep(Integer.MAX_VALUE);
    }

    @Test
    public void cli() throws InterruptedException
    {
        HazelcastInstance hz = Hazelcast.newHazelcastInstance();
        for (int i = 0; i < 100; i++)
        {
            ILock lock = hz.getLock("LOCK" + i);
            lock.lock();
        }
        Thread.sleep(Integer.MAX_VALUE);
    }

    private static class LockNameGather implements Callable<List<String>>, HazelcastInstanceAware, Serializable
    {
        transient HazelcastInstance hz;
        transient NodeEngineImpl node;

        @Override
        public List<String> call() throws Exception
        {
            node = ((HazelcastInstanceImpl) hz).node.getNodeEngine();
            LockService svc = node.getService(LockService.SERVICE_NAME);

            return svc.getAllLocks()
                      .stream()
                      .map(LockResource::getKey)
                      .map(d -> node.getSerializationService().createObjectDataInput(d))
                      .map((r) -> {
                          try
                          {
                              return r.readUTF();
                          } catch (IOException e)
                          {
                              throw new RuntimeException(e);
                          }
                      }).collect(Collectors.toList());
        }

        @Override
        public void setHazelcastInstance(HazelcastInstance hazelcastInstance)
        {
            hz = hazelcastInstance;
        }
    }
}

Found a way with many tricks,works with any service 
Run svr first, then run cli and test. 
public class PlayHZ
{
    @Test
    public void test() throws ExecutionException, InterruptedException
    {
        HazelcastInstance hz = Hazelcast.newHazelcastInstance();
        IExecutorService executor = hz.getExecutorService("gather");
        Map<Member, Future<List<String>>> futures = executor.submitToAllMembers(new LockNameGather());
        Thread.sleep(1000);
        System.out.println("Found in member");
        for (Map.Entry<Member, Future<List<String>>> entry : futures.entrySet())
        {
            System.out.printf("%s -> %s\n", entry.getKey(), entry.getValue().get());
        }
    }

    @Test
    public void svr() throws InterruptedException
    {
        HazelcastInstance hz = Hazelcast.newHazelcastInstance();
        Thread.sleep(Integer.MAX_VALUE);
    }

    @Test
    public void cli() throws InterruptedException
    {
        HazelcastInstance hz = Hazelcast.newHazelcastInstance();
        for (int i = 0; i < 100; i++)
        {
            ILock lock = hz.getLock("LOCK" + i);
            lock.lock();
        }
        Thread.sleep(Integer.MAX_VALUE);
    }

    private static class LockNameGather implements Callable<List<String>>, HazelcastInstanceAware, Serializable
    {
        transient HazelcastInstance hz;
        transient NodeEngineImpl node;

        @Override
        public List<String> call() throws Exception
        {
            node = ((HazelcastInstanceImpl) hz).node.getNodeEngine();
            LockService svc = node.getService(LockService.SERVICE_NAME);

            return svc.getAllLocks()
                      .stream()
                      .map(LockResource::getKey)
                      .map(d -> node.getSerializationService().createObjectDataInput(d))
                      .map((r) -> {
                          try
                          {
                              return r.readUTF();
                          } catch (IOException e)
                          {
                              throw new RuntimeException(e);
                          }
                      }).collect(Collectors.toList());
        }

        @Override
        public void setHazelcastInstance(HazelcastInstance hazelcastInstance)
        {
            hz = hazelcastInstance;
        }
    }
}
