AJ学IOS（06）UI之iOS热门游戏_超级猜图

AJ分享，必须精品

先看效果图

思路

需求分析

1，搭建界面
1》上半部分，固定的，用Storyboard直接连线(OK)
2》下半部分，根据题目的变化，不断变化和调整，用代码方式实现比较合适(OK)
*备选按钮区域(OK)
*答案按钮区域(OK)

2，编写代码
1》大图，小图的切换（OK）
2》下一题(OK)
3》备选按钮的点击，让文字进入答案区(Ok)
4》判断对错胜负(OK)
*胜利：进入下一题(OK)
*失败：提示用户重新选择(OK)
5》答案按钮的点击(OK)
把答案区的文字回复到备选区域(Ok)

上面是全部代码，
学习过程首先自己拖界面上半部分，需求里面写的很清楚了，

注释当中写的相当清楚，每个mark都间隔出来了部分的功能，因为是学习写的代码，所以注释写的很全，应该可以看懂。

完成布局后就开始写模型字典了。这里就用到了mvc设计模式，当然这个游戏中主要用到的时mc view方面并不是那么多，主要是对设计逻辑的学习与体现。

然后就按照需求来设计学习编写啦。
