YYKit系列之——YYModel使用
JSON转字符串普通字典转模型模型属性有自定义的模型YYUSer属性有数组（数组里自定义模型），还有字典和集合字典里的key与模型里的属性名不一致
常用的几个方法：
# json转模型
+ (instancetype)yy_modelWithJSON:(id)
# 模型转字符串
- (NSString *)yy_modelToJSONString
# 字典转模型
+ (instancetype)yy_modelWithDictionary:(NSDictionary *)
# 声明数组、字典或者集合里的元素类型时要重写
+ (nullable NSDictionary&NSString *, id& *)modelContainerPropertyGenericClass；
# 字典里的key值与模型的属性值不一致要重复
+ (nullable NSDictionary&NSString *, id& *)modelCustomPropertyM
# 下面两者是属性值在两个dic与模型之间的转化方法（自己看代码吧~
- (BOOL)modelCustomTransformFromDictionary:(NSDictionary *)dic ；
- (BOOL)modelCustomTransformToDictionary:(NSMutableDictionary *)dic；代码演示和转模型注释：一、JSON转字符串执行代码：// JSON -&模型 （内部实现：json -& 字典 -& 模型）
YYBook *book = [YYBook yy_modelWithJSON:@&
\&name\&: \&Harry Potter\&,
\&pages\&: 512,
\&publishDate\&: \&\&
//模型 -& 字符串
NSString *bookJSON = [book yy_modelToJSONString];
NSLog(@&Book: 二、普通字典转模型模型代码：@property (nonatomic, copy) NSString *
@property (nonatomic, assign) uint64_
@property (nonatomic, strong) NSDate *publishD执行代码： NSDictionary *dic = @{
@&name&: @&Harry Potter&,
@&pages&: @(512),
@&publishDate&: @&&
YYBook *book1 = [YYBook yy_modelWithDictionary:dic];
NSString *bookJSON1 = [book1 yy_modelToJSONString];
NSLog(@&bookJSON: %@&,bookJSON1);三、模型属性有自定义的模型YYUSer模型代码：@property (nonatomic, assign) uint64_
@property (nonatomic, copy) NSString *
@property (nonatomic, strong) NSDate *createT
@property (nonatomic, strong) YYUser *
#自定义模型执行代码：NSDictionary *dic = @{
@&rid&: @(),
@&name&: @&YYKit&,
@&createTime& : @&T06:24:26Z&,
@&owner&: @{
@&uid& : @(989898),
@&name& : @&mawenxing&
YYRepo *repo1 = [YYRepo yy_modelWithDictionary:dic];
NSLog(@&Repo1: %@\nowner.name=%@&, repo1.name,repo1.owner.name);四、属性有数组属性里有数组（数组里自定义模型），还多字典和集合模型代码：# YYAlbum.h
@property (nonatomic, copy) NSString *
@property (nonatomic, strong) NSArray * # Array&YYPhoto&
@property (nonatomic, strong) NSDictionary *likedU # Key:name(NSString) Value:user(YYUser)
@property (nonatomic, strong) NSSet *likedUserI # Set&NSNumber&
# YYPhoto.h
@property (nonatomic, copy) NSString *
@property (nonatomic, copy) NSString *
# YYAlbum.m
#把数组里面带有对象的类型专门按照这个方法，这个格式写出来
-(nullable NSDictionary&NSString *, id& *)modelContainerPropertyGenericClass{
: YYPhoto.class,
@&likedUsers&
: YYUser.class,
@&likedUserIds& : NSNumber.class
}执行代码：///源代码这里有些成字典的，大家如果看不懂这个JSON可以看字典
YYAlbum *album = [YYAlbum yy_modelWithJSON:@&
\&name\& : \&Happy Birthday\&,
\&photos\& : [
\&url\&:\&/1.png\&,
\&desc\&:\&Happy~\&
\&url\&:\&/2.png\&,
\&desc\&:\&Yeah!\&
\&likedUsers\& : {
\&Jony\& : {\&uid\&:10001,\&name\&:\&Jony\&},
\&Anna\& : {\&uid\&:10002,\&name\&:\&Anna\&}
\&likedUserIds\& : []
NSString *albumJSON = [album yy_modelToJSONString];
NSLog(@&Album: 五、字典里的属性名与模型里的属性名不一致模型代码：# YYMessage.h
@property (nonatomic, assign) uint64_t messageId;
@property (nonatomic, strong) NSString *
@property (nonatomic, strong) NSDate *
# YYMessage.m
+ (nullable NSDictionary&NSString *, id& *)modelCustomPropertyMapper{
return @{@&messageId&:@&i&,
@&content&:@&c&,
@&time&:@&t&};
- (BOOL)modelCustomTransformFromDictionary:(NSDictionary *)dic {
self.time = (NSDate *)[NSDate dateWithTimeIntervalSince1970:[dic[@&t&] doubleValue]/1000];
return YES;
- (BOOL)modelCustomTransformToDictionary:(NSMutableDictionary *)dic {
dic[@&t&] = @([self.time timeIntervalSince1970] * 1000).description;
return YES;
}执行代码：
NSDictionary *dic = @{@&i&:@,
@&c&:@&Hello&,
YYMessage *message = [YYMessage yy_modelWithDictionary:dic];
NSString *messageJSON = [message yy_modelToJSONString];
NSLog(@&messageJSON: %@&, messageJSON);
YYMessage *message = [YYMessage yy_modelWithJSON:@&{\&i\&:\&\&,\&c\&:\&Hello\&,\&t\&:\&0\&}&];
NSString *messageJSON = [message yy_modelToJSONString];
NSLog(@&messageJSON: %@&, messageJSON);演示源码：开篇说明：&虽然网上有很多讲解YYModel使用方法的文章，包括YYModel作者也在github上对其做了使用说明。&但在我实际使用过程中，依然发现文档的不完善，比如对于复杂的模型（如多层嵌套）讲解的仍不透彻，同时本文也会介绍一神器配合YYModel使用，让你感受分分钟搞定模型创建的酸爽。&当然为了减少读者的学习成本，本会对YYModel作者的文档进行丰富和扩展。可在github上下载，以便更直观了解各种使用场景详细代码。&文章只要包含：详解YYModel的多种使用场景拓展插件，让你一分钟搞定所有的模型的创建和调用。一、YYModel的使用场景1.简单的 Model 与 JSON 相互转换&code class=&hljs objectivec has-numbering& style=&display: padding: 0 color: box-sizing: border- font-family: &Source Code Pro&,font-size: white-space: border-radius: 0 word-wrap: background:&&&span class=&hljs-comment& style=&color: rgb(136, 0, 0); box-sizing: border-&&// JSON:&/span&
