iOS 中的Model 转 Model mdoel的copy 应

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 *secondModel = NSStringFromClass([object class]);
    
    NSString *dicKey = [NSString stringWithFormat:@"%@%@%@",firstModel,ConversionKey,secondModel];
    
    NSDictionary *dic = [[BaseConversion getInstance].modelDic valueForKey:dicKey];
    
    if (dicKey == nil) {
