随着项目越来越大，项目model 更是数不胜数，当我们遇到一个model 想去转换另一个model 的时候，经常会写一些非常恶心的代码。
每次去看都非常的影响心情，所以决定干掉他。来吧 baby
先看看这样的代码有多么恶心，来
//动物怎么变成人
Animal *animal = [[Animal alloc]init];
animal.animalName = @"猿";
animal.animalAge = @"20";
animal.animalSex = @"男";
animal.animalPower = @"Strong";
//long long wait
//变成人
People *people = [[People alloc]init];
people.peopleName = @"人";
people.peopleAge = animal.animalAge;
people.peopleSex = animal.animalSex;
people.peoplePower = animal.animalPower;
NSLog(@"animal %@-%@",animal.animalName,animal.animalPower);
NSLog(@"people %@-%@",people.peopleName,people.peoplePower);
这个世界就是这么来的，我也不想继承，继承带来的后果无法预知。就这样简简单单日子也是过，but 每天看着没有洗的碗筷在哪里放着，实在受不了。
所以打扫了一下，结果就是这样了：
//动物怎么变成人
[[BaseConversion getInstance] set_modelKeyValue:[People class]
andModel:[Animal class]
params:@{@"animalAge":@"peopleAge",
@"animalSex":@"peopleSex",
@"animalPower":@"peoplePower"
}];
Animal *animal = [[Animal alloc]init];
animal.animalName = @"猿";
animal.animalAge = @"20";
animal.animalSex = @"男";
animal.animalPower = @"Strong";
//long long wait
//变成人
People *people = [People set_keysAndValuesToModel:animal];
people.peopleName = @"人";
NSLog(@"animal %@-%@",animal.animalName,animal.animalPower);
NSLog(@"people %@-%@",people.peopleName,people.peoplePower);
好点了没，不要书行数好吗？
来看看一个方法啊
[[BaseConversion getInstance] set_modelKeyValue:[People class]
andModel:[Animal class]
params:@{@"animalAge":@"peopleAge",
@"animalSex":@"peopleSex",
@"animalPower":@"peoplePower"
}];
定义了转换model的属性key,一一对应，双向转换。
使用的时候只用一行就好了
People *people = [People set_keysAndValuesToModel:animal];
简单实用，代码一点点。下边是源码：喜欢的点个赞，我会在把她丰富一些给大家下载的。

NSString *firstModel = NSStringFromClass([self class]);
NSString *secondModel = NSStringFromClass([object class]);

NSDictionary *dic = [[BaseConversion getInstance].modelDic valueForKey:dicKey];
if (dicKey == nil) {
return nil;
}

}
}
}
