IOS15之JSON的解析字典轉(zhuǎn)模型

IOS15字典轉(zhuǎn)模型 基于 iPhone13運(yùn)行的。
涉及KVC，

#import <Foundation/Foundation.h> NS_ASSUME_NONNULL_BEGIN @interface AHLJProduct : NSObject @property(nonatomic,copy)NSString * title; //id是蘋果的關(guān)鍵字，不能直接使用 @property(nonatomic,copy)NSString * ids; @property(nonatomic,copy)NSString * url; @property(nonatomic,copy)NSString * icon; @property(nonatomic,copy)NSString * customUrl; //提供一個(gè)對(duì)象方法 -(instancetype)initWithDict:(NSDictionary *)dict; //提供一個(gè)類方法，對(duì)外暴露的類方法，給外界方便調(diào)用的 +(instancetype)productWithDict:(NSDictionary *)dict; @end NS_ASSUME_NONNULL_END #import "AHLJProduct.h" @implementation AHLJProduct - (instancetype)initWithDict:(NSDictionary *)dict{self = [super init];if (self) {//使用KVC[self setValuesForKeysWithDictionary:dict];//對(duì)ID單獨(dú)處理self.ids = dict[@"id"];}return self; } + (instancetype)productWithDict:(NSDictionary *)dict{return [[self alloc] initWithDict:dict]; } //屬性比json字段多的時(shí)候 就要重寫這個(gè)方法 - (void)setValue:(id)value forUndefinedKey:(NSString *)key{} - (NSString *)description {return [NSString stringWithFormat:@"< %p %@, {title: %@,url: %@, id,%@,customUrl %@,icon: %@}>", self, [self class],self.title,self.url,self.ids,self.customUrl,self.icon]; } @end //懶加載 - (NSArray *)products{if(!_products){NSString *path = [[NSBundle mainBundle] pathForResource:@"more_project.json" ofType:nil];NSData *data = [NSData dataWithContentsOfFile:path];//NSJSONReadingMutableContainers 可變的容器NSArray *dataArray = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];NSMutableArray *mArr = [NSMutableArray array];for(NSDictionary *dict in dataArray){[mArr addObject:[AHLJProduct productWithDict:dict]];}_products = mArr;}return _products; }
