 856
 00:43:25,136 --> 00:43:28,271
 Well, this is one where I don't mind if someone asks
+嘛，这个我不介意如果其他人知道
 
 857
 00:43:28,340 --> 00:43:30,706
 what the number of pairs of cards is but
+有多少对卡片，但是
 
 858
 00:43:30,775 --> 00:43:36,612
 setting the number of pairs of cards would be bad. But
+设置有多少对卡片是不好的。但
 
 859
 00:43:36,680 --> 00:43:40,816
 the thing about this is it's already a get-only property.
+这个的话，它已经是只读的属性了
 
 860
 00:43:40,885 --> 00:43:43,419
 You can't set it anyway, it derives it from other data.
+你怎么都没法设置它，它是从其他数据衍生出来的
 
 861
 00:43:43,488 --> 00:43:47,022
 So we're just gonna make this private, sorry, not private.
+所以我们就让他是 private 的。不好意思，让他不是 private
 
 862
 00:43:47,091 --> 00:43:49,358
 And we're gonna allow people to call this,
+我们要让别人能够访问这个
 
 863
 00:43:49,427 --> 00:43:51,493
 people who are using my ViewController, they can say,
+使用我这个 ViewController 人可以问
 
 864
 00:43:51,562 --> 00:43:53,496
 how many pairs of cards are there? But they can't set it,
+这里有多少对卡片，但他们不能给它赋值
 
 865
 00:43:53,565 --> 00:43:55,998
 cuz this is not settable anyway. Okay, so
+因为这个本来就没法赋值。好，所以
 
 866
 00:43:56,067 --> 00:43:57,366
 that's okay to make that in public.
+这个是可以公开的
 
 867
 00:43:57,435 --> 00:43:59,902
 Same thing flipCount, I think flipCount,
+flipCount 也是类似的，我认为 flipCount
 
 868
 00:43:59,970 --> 00:44:03,272
 it's okay for people to get it, but definitely, we don't
+人们是可以读取它的，但肯定我们不
 
 869
 00:44:03,341 --> 00:44:06,508
 want people setting flipCount. That's something we do
+想让人们赋值给 flipCount。那是我们
 
 870
 00:44:06,577 --> 00:44:08,978
 internally when the cards are flip, we implement flipCount.
+在翻牌的时候内部实现的，我们管理的
 
 871
 00:44:09,046 --> 00:44:12,148
 So that's private for the setter, but will allow people
+所以 setter 是 private 的，但我们允许其他人
 
 872
 00:44:12,216 --> 00:44:14,684
 to get the flipCount who are using our thing.
+在使用的时候获得 flipCount
 
 873
 00:44:14,752 --> 00:44:19,021
 Our outlets, almost always we have private outlets.
+我们这些 @IBOutlet，几乎我们都是让出口保持 private
 
 874
 00:44:19,090 --> 00:44:19,989
 Cuz our private outlets,
+因为我们私有的出口
 
 875
 00:44:20,057 --> 00:44:23,159
 these things, and even our actions these are all kind of
+这些，甚至包括 @IBAction 操作，这些都是
 
 876
 00:44:23,227 --> 00:44:26,295
 internal implementation of how we implement our UI.
+内部对 UI 的实现
 
 877
 00:44:26,364 --> 00:44:29,365
 That's what a ViewController does it controls our UI.
+这就是视图控制器的作用，控制 UI
 
 878
 00:44:29,433 --> 00:44:32,702
 Definitely something like update model from UI would be
+肯定类似于 updateViewFromModel 的方法
 
 879
 00:44:32,771 --> 00:44:35,271
 private, that's internal implementation.
+应该是 private 的，这也是内部实现
 
 880
 00:44:35,339 --> 00:44:38,808
 All this emoji business that's all private. Although you
+这些表情相关的也应该是 private 的，虽然
 
 881
 00:44:38,876 --> 00:44:42,845
 could imagine trying to expose some public API eventually
+你可以计划尝试最终暴露些公有 API
 
 882
 00:44:42,914 --> 00:44:45,848
 in this ViewController that let's someone who's using
+让其他使用 ViewController 的人可以
 
 883
 00:44:45,917 --> 00:44:49,051
 our ViewController specify the emojis they want.
+指定他们想用的表情
 
 884
 00:44:49,120 --> 00:44:53,756
 Like, you know, this theme required task that you have,
+比如某个任务要求用某个主题
 
 885
 00:44:53,824 --> 00:44:57,460
 you could imagine that there was a way to specify I want

 886
 00:44:57,528 --> 00:44:59,995
 you mister view controller to play this game,
+ViewController 玩这个游戏
 
 887
 00:45:00,064 --> 00:45:02,998
 but I want you to use this emoji as your theme.
+但是我想要用这套表情作为主题
 
 888
 00:45:03,067 --> 00:45:05,534
 See, so you could imagine that something being public.
+所以设想那种情况下肯定会是有公开的
 
 889
 00:45:05,603 --> 00:45:08,471
 I don't think it would be exactly this API,
+但我不认为会是和这个一样的 API
 
 890
 00:45:08,539 --> 00:45:10,439
 it would be some other kind of API,
+那会是不同的 API
 
 891
 00:45:10,508 --> 00:45:13,942
 I'm not sure what they would let you set the emoji to
+我不确定是什么样的，但它能让你设置使用的表情
 
 892
 00:45:14,011 --> 00:45:16,946
 use. We can't really make this public cuz we actually consume
+这个我们是不能公开的，因为我们实际会消耗
 
 893
 00:45:17,014 --> 00:45:20,883
 this. This is a var and we consume it. We have obviously
+这个数组；这是个变量，而我们会移除里面的内容。肯定
 
 894
 00:45:20,952 --> 00:45:23,119
 had to deal with that in your homework I'm sure. And
+在你们的作业里要解决这个问题。还有
 
 895
 00:45:23,187 --> 00:45:24,954
 you know, this dictionary we're building on a fly,
+你知道的，这个字典我们是及时构建的
 
 896
 00:45:25,022 --> 00:45:26,755
 we wouldn't want anyone messing with it, so
+我们不会想其他人使用它，所以
 
 897
 00:45:26,824 --> 00:45:27,857
 I'm gonna keep all this private.
+我让这些都是 private 的
 
 898
 00:45:27,925 --> 00:45:30,259
 This is an example of making it private first and
+这就是个例子，先让这些都是 private
 
 899
 00:45:30,328 --> 00:45:33,296
 then I'm gonna think about what I want to be public.
+之后我再考虑我要公开哪些
 
 900
 00:45:33,364 --> 00:45:34,997
 You see, the design approach there?
+看到我们用的设计方法了吗？
