归档－对模型数组对象（存储到本地的plist文件）也数组里存放的是模型

一、模型文件

（1）JLMainViewsModel.h文件必须遵循 NSCoding协议

@interface JLMainViewsModel : NSObject<NSCopying,NSCoding>

（2）JLMainViewsModel.m文件实现代理方法

 @implementation JLMainViewsModel

 -(void)encodeWithCoder:(NSCoder *)aCoder{

     [aCoder encodeObject:self.fromSource forKey:@"fromSource"];

     [aCoder encodeObject:self.url forKey:@"url"];

     [aCoder encodeObject:self.title forKey:@"title"];

     [aCoder encodeObject:self.type forKey:@"type"];

     [aCoder encodeObject:self.newsTime forKey:@"newsTime"];

     [aCoder encodeObject:self.imageUrl forKey:@"imageUrl"];

     [aCoder encodeObject:self.imageArray forKey:@"imageArray"];

     [aCoder encodeObject:self.bigImageUrl forKey:@"bigImageUrl"];

     [aCoder encodeObject:self.bigImageArray forKey:@"bigImageArray"];

     [aCoder encodeObject:self.recommend forKey:@"recommend"];

     [aCoder encodeObject:self.exData forKey:@"exData"];

     [aCoder encodeObject:self.newsType forKey:@"newsType"];

     [aCoder encodeObject:self.style forKey:@"style"];

     [aCoder encodeObject:self.gzh forKey:@"gzh"];

     [aCoder encodeObject:self.uniqId forKey:@"uniqId"];

     [aCoder encodeObject:self.subdesc forKey:@"subdesc"];

     [aCoder encodeObject:self.autoplay forKey:@"autoplay"];

     [aCoder encodeObject:self.fromicon forKey:@"fromicon"];

     [aCoder encodeObject:self.webUrl forKey:@"webUrl"];

 }

 -(id)initWithCoder:(NSCoder *)aDecoder{

     if (self = [super init]) {

         self.fromSource = [aDecoder decodeObjectForKey:@"fromSource"];

         self.url = [aDecoder decodeObjectForKey:@"url"];

         self.title = [aDecoder decodeObjectForKey:@"title"];

         self.type = [aDecoder decodeObjectForKey:@"type"];

         self.newsTime = [aDecoder decodeObjectForKey:@"newsTime"];

         self.imageUrl = [aDecoder decodeObjectForKey:@"imageUrl"];

         self.imageArray = [aDecoder decodeObjectForKey:@"imageArray"];

         self.bigImageUrl = [aDecoder decodeObjectForKey:@"bigImageUrl"];

         self.bigImageArray = [aDecoder decodeObjectForKey:@"bigImageArray"];

         self.recommend = [aDecoder decodeObjectForKey:@"recommend"];

         self.exData = [aDecoder decodeObjectForKey:@"exData"];

         self.newsType = [aDecoder decodeObjectForKey:@"newsType"];

         self.style = [aDecoder decodeObjectForKey:@"style"];

         self.gzh = [aDecoder decodeObjectForKey:@"gzh"];

         self.uniqId = [aDecoder decodeObjectForKey:@"uniqId"];

         self.subdesc = [aDecoder decodeObjectForKey:@"subdesc"];

         self.autoplay = [aDecoder decodeObjectForKey:@"autoplay"];

         self.fromicon = [aDecoder decodeObjectForKey:@"fromicon"];

         self.webUrl = [aDecoder decodeObjectForKey:@"webUrl"];

     }

     return self;

 }

 - (id)copyWithZone:(NSZone *)zone

 {

     JLMainViewsModel *model = [[[self class] allocWithZone:zone]init];

     return model;

 }

 @end

二、对模型数组进行存储到本地

 //此段代码紧紧只是为了说明 存储段数组 是模型数组

                 NSMutableArray *mArray = [NSMutableArray array];

                 //字典转模型

                 for (NSDictionary *dict  in array) {

                     JLMainViewsModel *news = [JLMainViewsModel newsWithDict:dict];

                     [mArray addObject:news];

                 }

这段代码才是存储操作

 //1.获取存储的路径

                     NSString *documents = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

                     NSString *filePatha = [documents stringByAppendingPathComponent:@"newsModelWithArray.plist"];

                     //归档

                     [NSKeyedArchiver archiveRootObject:mArray toFile:filePatha];

三、读取归档的数据

 #pragma  mark - 获取本地缓存(归档)

 -(BOOL)getNwsDataUnarchiver{

     NSString *documents = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)lastObject];

     NSString *filePath = [documents stringByAppendingPathComponent:@"newsModelWithArray.plist"];

     NSMutableArray<JLMainViewsModel *> *newsModelList = [NSKeyedUnarchiver unarchiveObjectWithFile:filePath];

     if (newsModelList.count > ) {

         self.dataArray = newsModelList.mutableCopy;

         return YES;

     }

     return NO;

 }
