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;
}
