26 | @property NSString *name; 27 | @property NSDate *created; 28 | @end 29 | 30 | @implementation User 31 | 32 | @end 33 | ``` 34 | -------- 35 | ``` 36 | // 将 JSON (NSData,NSString,NSDictionary) 转换为 Model: 37 | User *user = [User yy_modelWithJSON:json]; 38 | 39 | // 将 Model 转换为 JSON 对象: 40 | NSDictionary *json = [user yy_modelToJSONObject]; 41 | ``` 42 | 43 | JSON/Dictionary 中的对象类型与 Model 属性不一致时，YYModel 将会进行如下自动转换。自动转换不支持的值将会被忽略，以避免各种潜在的崩溃问题。 44 | ![格式自动转换.png](http://upload-images.jianshu.io/upload_images/1467716-33ae643a0ca314fa.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 45 | -------- 46 | 47 | #### 2.Model 属性名和 JSON 中的 Key 不相同 48 | 49 | ``` 50 | // JSON: 51 | { 52 |     "n":"Harry Pottery", 53 |     "p": 256, 54 |     "ext" : { 55 |         "desc" : "A book written by J.K.Rowing." 56 |     }, 57 |     "ID" : 100010 58 | } 59 | 60 | // Model: 61 | @interface Book : NSObject 62 | @property NSString *name; 63 | @property NSInteger page; 64 | @property NSString *desc; 65 | @property NSString *bookID; 66 | @end 67 | @implementation Book 68 | //返回一个 Dict，将 Model 属性名对映射到 JSON 的 Key。 69 | + (NSDictionary *)modelCustomPropertyMapper { 70 |     return @{@"name" : @"n", 71 |              @"page" : @"p", 72 |              @"desc" : @"ext.desc", 73 |              @"bookID" : @[@"id",@"ID",@"book_id"]}; 74 | } 75 | @end 76 | ``` 77 | 你可以把一个或一组 json key (key path) 映射到一个或多个属性。如果一个属性没有映射关系，那默认会使用相同属性名作为映射。 78 | 在 json->model 的过程中：如果一个属性对应了多个 json key，那么转换过程会按顺序查找，并使用第一个不为空的值。 79 | 在 model->json 的过程中：如果一个属性对应了多个 json key (key path)，那么转换过程仅会处理第一个 json key (key path)；如果多个属性对应了同一个 json key，则转换过过程会使用其中任意一个不为空的值。 80 | -------- 81 | 82 | ### 3.Model 包含其他 Model 83 | 84 | ``` 85 | // JSON 86 | { 87 |     "author":{ 88 |         "name":"J.K.Rowling", 89 |         "birthday":"1965-07-31T00:00:00+0000" 90 |     }, 91 |     "name":"Harry Potter", 92 |     "pages":256 93 | } 94 | 95 | // Model: 什么都不用做，转换会自动完成 96 | @interface Author : NSObject 97 | @property NSString *name; 98 | @property NSDate *birthday; 99 | @end 100 | @implementation Author 101 | @end 102 | 103 | @interface Book : NSObject 104 | @property NSString *name; 105 | @property NSUInteger pages; 106 | @property Author *author; //Book 包含 Author 属性 107 | @end 108 | @implementation Book 109 | @end 110 | ``` 111 | -------- 112 | 113 | ### 4.容器类属性 114 | 115 | ``` 116 | @class Shadow, Border, Attachment; 117 | 118 | @interface Attributes 119 | @property NSString *name; 120 | @property NSArray *shadows; //Array 121 | @property NSSet *borders; //Set 122 | @property NSMutableDictionary *attachments; //Dict 123 | @end 124 | 125 | @implementation Attributes 126 | // 返回容器类中的所需要存放的数据类型 (以 Class 或 Class Name 的形式)。 127 | + (NSDictionary *)modelContainerPropertyGenericClass { 128 |     return @{@"shadows" : [Shadow class], 129 |              @"borders" : Border.class, 130 |              @"attachments" : @"Attachment" }; 131 | } 132 | @end 133 | ``` 134 | 在实际使用过过程中，`[Shadow class]`，`Border.class`，`@"Attachment"`没有明显的区别。 135 | 这里仅仅是创建作者有说明，实际使用时，需要对其遍历，取出容器中得字典，然后继续字典转模型。（****YYModel****的核心是通过****runtime****获取结构体中得****Ivars****的值，将此值定义为****key,****然后给****key****赋****value****值，所以我们需要自己遍历容器（****NSArray****，****NSSet****，****NSDictionary****），获取每一个值，然后****KVC****）。 136 | 137 | 138 | -------- 139 | 140 | - 具体的代码实现如下： 141 | 142 | ``` 143 | NSDictionary *json =[self getJsonWithJsonName:@"ContainerModel"]; 144 | ContainerModel *containModel = [ContainerModel yy_modelWithDictionary:json]; 145 | NSDictionary *dataDict = [containModel valueForKey:@"data"]; 146 | //定义数组，接受key为list的数组 147 | self.listArray = [dataDict valueForKey:@"list"];  148 |  //遍历数组 149 | [self.listArray enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) { 150 |         NSDictionary *listDict = obj; 151 |         //获取数组中得字典 152 |         List *listModel = [List yy_modelWithDictionary:listDict]; 153 |         //获取count 和 id 154 |         NSString *count = [listModel valueForKey:@"count"]; 155 |         NSString *id = [listModel valueForKey:@"id"]; 156 |         157 | ``` 158 | -------- 159 | 160 | ### 5.黑名单与白名单 161 | 162 | ``` 163 | @interface User 164 | @property NSString *name; 165 | @property NSUInteger age; 166 | @end 167 | 168 | @implementation Attributes 169 | // 如果实现了该方法，则处理过程中会忽略该列表内的所有属性 170 | + (NSArray *)modelPropertyBlacklist { 171 |     return @[@"test1", @"test2"]; 172 | } 173 | // 如果实现了该方法，则处理过程中不会处理该列表外的属性。 174 | + (NSArray *)modelPropertyWhitelist { 175 |     return @[@"name"]; 176 | } 177 | @end 178 | ``` 179 | 180 | -------- 181 | 182 | ### 6.数据校验与自定义转换 183 | 实际这个分类的目的比较简单和明确。 184 | 就是对判断是否为时间戳，然后对时间戳进行处理，调用 185 | `_createdAt = [NSDate dateWithTimeIntervalSince1970:timestamp.floatValue];` 186 | 获取时间。 187 | 188 | ``` 189 | // JSON: 190 | { 191 |     "name":"Harry", 192 |     "timestamp" : 1445534567     //时间戳 193 | } 194 | 195 | // Model: 196 | @interface User 197 | @property NSString *name; 198 | @property NSDate *createdAt; 199 | @end 200 | 201 | @implementation User 202 | // 当 JSON 转为 Model 完成后，该方法会被调用。 203 | // 你可以在这里对数据进行校验，如果校验不通过，可以返回 NO，则该 Model 会被忽略。 204 | // 你也可以在这里做一些自动转换不能完成的工作。 205 | - (BOOL)modelCustomTransformFromDictionary:(NSDictionary *)dic { 206 |     NSNumber *timestamp = dic[@"timestamp"]; 207 |     if (![timestamp isKindOfClass:[NSNumber class]]) return NO; 208 |     _createdAt = [NSDate dateWithTimeIntervalSince1970:timestamp.floatValue]; 209 |     return YES; 210 | } 211 | 212 | // 当 Model 转为 JSON 完成后，该方法会被调用。 213 | // 你可以在这里对数据进行校验，如果校验不通过，可以返回 NO，则该 Model 会被忽略。 214 | // 你也可以在这里做一些自动转换不能完成的工作。 215 | - (BOOL)modelCustomTransformToDictionary:(NSMutableDictionary *)dic { 216 |     if (!_createdAt) return NO; 217 |     dic[@"timestamp"] = @(n.timeIntervalSince1970); 218 |     return YES; 219 | } 220 | @end 221 | ``` 222 | 223 | > - 需要注意的时，如果用插件，对时间戳类型或默认创建为NSUInteger类型，需要将其更改为NSDate类型。 224 | 225 | -------- 226 | 227 | ### 7.Coding/Copying/hash/equal/description 228 | 以下方法都是YYModel的简单封装，实际使用过程和系统方法区别不大。对其感兴趣的可以点进方法内部查看。 229 | 230 | ``` 231 | @interface YYShadow :NSObject 232 | @property (nonatomic, copy) NSString *name; 233 | @property (nonatomic, assign) CGSize size; 234 | @end 235 | 236 | @implementation YYShadow 237 | // 直接添加以下代码即可自动完成 238 | - (void)encodeWithCoder:(NSCoder *)aCoder {  239 | [self yy_modelEncodeWithCoder:aCoder];  240 | } 241 | - (id)initWithCoder:(NSCoder *)aDecoder { 242 | self = [super init];
