Question

我尝试在此代码中使用TFHlle解析html将对象添加到我的可变数组中，但它在我的数组中为对象返回null，但是在for循环中，我记录了'[element objectForKey：@]的结果“title”]'并返回我想要的结果。

如何将元素[objectForKey:@"title"]的结果添加到我的数组中？

TFHpple *htmlParseResult = [TFHpple hppleWithHTMLData:self.responseData];
NSString *coursesXpathQueryString = @"//h2[@class='main']/a";
NSArray *coursesNodes = [htmlParseResult searchWithXPathQuery:coursesXpathQueryString];
NSMutableArray *fitCourse = [[NSMutableArray alloc] initWithCapacity:0];

for (TFHppleElement *element in coursesNodes) {
    [fitCourse addObject:[element objectForKey:@"title"]];
}

我认为

   var valuedCustomer = new ValuedCustomerSpecification();
   //1. You can use this statement to check if a customer is valued or not in your domain
   Customer customer = ....
   if(valuedCustomer.IsSatisfiedBy(customer))

   //2. You can use it to get just valued customers from repository, 
   var valuedCustomers = repository.Get(valuedCustomer);

   //3. You can combine it with other specifications to create composite specifications. Following syntax can vary with implementation
   var seniorValuedCustomer = valuedCustomer.And(seniorCustomer)

应该改为：

NSArray *coursesNodes = [htmlParseResult searchWithXPathQuery:coursesXpathQueryString];

我不确定这是否有效，但你可以试试。

无法使用TFHpple将对象添加到NSMutableArray
