iOS数据模型存储的时候哈希生成对面俩个模型是否相等

-(NSUInteger)hash
{
return [[NSString stringWithFormat:@"%@_%@",self.name,self.address] hash];
}

-(BOOL)isEqual:(id)object
{
YWDLocationEntity *obj = object;
if ([object isKindOfClass:self.class]) {
//        return [[NSString stringWithFormat:@"%@%@",self.name,self.address] isEqualToString:[NSString stringWithFormat:@"%@%@",obj.name,obj.address]];
return [self.name isEqualToString:obj.name];
}
return NO;
}
