使用Archiver crash

[billLiao]

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -decodeObjectForKey: only defined for abstract class.  Define -[NSKeyedArchiver decodeObjectForKey:]!'

代码是：

- (instancetype)initWithCoder:(NSCoder *)aDecoder
{
    self = [super init];
    return [self yy_modelInitWithCoder:aDecoder];
}
- (void)encodeWithCoder:(NSCoder *)aCoder
{
    [self yy_modelInitWithCoder:aCoder];
}
