Archive&Unarchive

Archive（歸檔）

需要歸檔的對象必須要遵循NSCoding協議，那麼在調用archiverRootObject方法的時候，會自動調用該對象的encodeWithCoder方法

- (void)encodeWithCoder:(NSCoder *)aCoder{    [aCoder encodeObject:_name forKey:@"name"];    [aCoder encodeInteger:_age forKey:@"age"];    [aCoder encodeObject:_tel forKey:@"tel"];    [aCoder encodeObject:_icon forKey:@"icon"];}

 

Unarchive（恢複）

需要恢複的對象在調用unarchiveObjectWithFile方法的時候，會自動調用該對象的initWithCoder方法

- (id)initWithCoder:(NSCoder *)aDecoder{    NSLog(@".....");    _name = [aDecoder decodeObjectForKey:@"name"];    _age = [aDecoder decodeIntegerForKey:@"age"];    _tel = [aDecoder decodeObjectForKey:@"tel"];    _icon = [aDecoder decodeObjectForKey:@"icon"];    return self;}
