我不知道为什么在尝试归档对象时会收到“无法识别的选择器发送给实例”的信息。
最佳答案
您需要在Furniture对象中实现NSCoding协议(protocol):
- (void)encodeWithCoder:(NSCoder *)aCoder{
[aCoder encodeObject:self.yourpoperty forKey:@"PROPERTY_KEY"];
}
-(id)initWithCoder:(NSCoder *)aDecoder{
if(self = [super init]){
self.yourpoperty = [aDecoder decodeObjectForKey:@"PROPERTY_KEY"];
}
return self;
}
基本上,您指定应该写入(编码)和从文件读取(解码)的内容。通常,对于要存储在文件中的每个属性,您所做的与我在示例中所做的相同。
