iOS-FMDB+runtime封装,简单实用,省去复杂的sql语句.

问题提出:

开发中需要用到Sqlite数据库，当然就要写一堆复杂的sql语句。如下:

创建表：

（1）CREATE TABLE IF NOT EXISTS BSUser (id integer(11) PRIMARY KEY ,arr text DEFAULT NULL,data text DEFAULT NULL,stu_id long DEFAULT NULL,name text DEFAULT NULL,image text DEFAULT NULL);
（2）CREATE TABLE IF NOT EXISTS BSTeacher (id integer(11) PRIMARY KEY ,name text DEFAULT NULL,depart text DEFAULT NULL);
（3）CREATE TABLE IF NOT EXISTS BSStudent (id integer(11) PRIMARY KEY ,tea_id long DEFAULT NULL,name text DEFAULT NULL);

模糊查询：

select * from YHWorkGroup where id = 2016 and msgContent like '%我%' 

更新表:

update YHUserInfo set isRegister = 1,isSelfModel = 1,isOfficial = 1,isFollowed = 1,sex = 1,fromType = 1,dynamicCount = 1,nNewFansCount = 2,fansCount = 0,followCount = 28,likeCount = 4,identity = 1,friShipStatus = 1,addFriStatus = 2,photoCount = 0,updateStatus = 0,id = '201611110',taxAccount = 'accessToken=0',mobilephone = '13570871315',userName = 'userName0',avatarUrl = 'http://www.google.com',oriAvaterUrl = 'http://www.baidu.com',intro = '个人简介好短',industry = '随机行业',job = '高级职位',province = '广东省',workCity = '随机工作城市',workLocation = '广州移动',loginTime = '1479110498.98624',company = '广州移动通信',email = 'qq0.eamil.com',visitTime = '1479110598.98624',jobTags = '(
    "\U968f\U673a\U6807\U7b7e",
    "\U968f\U673a\U6807\U7b7e"
)',workExperiences = '[{"moreDescription":"玛丽黛佳法拉盛借方","endTime":"20164","company":"公司18","workExpId":"10","position":"职位29","beginTime":"20160"},{"moreDescription":"玛丽黛佳法拉盛借方","endTime":"20164","company":"公司33","workExpId":"14","position":"职位22","beginTime":"20160"},{"moreDescription":"玛丽黛佳法拉盛借方","endTime":"20164","company":"公司25","workExpId":"27","position":"职位21","beginTime":"20160"}]',eductaionExperiences = '[{"school":"学校36","major":"会计","beginTime":"20160","educationBackground":"大专","endTime":"20164","moreDescription":"的理解爱了就","eduExpId":"260"},{"school":"学校26","major":"随机专业","beginTime":"20160","educationBackground":"大专","endTime":"20164","moreDescription":"的理解爱了就","eduExpId":"380"},{"school":"学校38","major":"会计","beginTime":"20160","educationBackground":"本科","endTime":"20164","moreDescription":"的理解爱了就","eduExpId":"82"}]' where id = 201611110 ;

      在iOS开发中,为了得到以上SQL语句,如果是手动地添加模型属性,代码就冗余了，也就是增加代码量，可读性差，而且如果改变了模型的某个属性的名称,SQL语句相应的位置要发生改变。增，删，改，查，都要改变。如果是改变了一批属性名，这工作量简直是灾难性啊。还有,如果一个模型的属性嵌套模型,怎么把模型保存到数据库呢，如果属性是UIImage,或者是数组呢？怎么解决。

     那Apple有没有API可以动态的获取属性名，代替这复杂的语句呢？有，那就是runtime。相信大家对runtime已经很熟悉了。如果刚入门runtime，可以阅读标哥的技术博客的runtime专题，在那里帮你快速掌握runtime基本知识。好，现在就利用runtime对FMDB进行封装: 

      因为最近项目空闲，整理了一个基于FMDB封装了一个简单实用的APP数据管理工具YHFMDB.
