将HTML文件添加到Xcode中的表格视图

Question

我对iOS编程非常新颖。我目前正在使用故事板开发一个应用程序，并且我希望能够在表格中显示一系列7个HTML文件，点击每个文件后将显示格式化文本的HTML文件。

我已经搜索到了地球的尽头，并且找不到任何回答我如何实现这个问题的问题。

基本上应用程序有4个选项卡，第一个是文本，第二个是我想在表格中显示html文件（称为工具箱）的地方，第三个是Web浏览器，最后是文本。

我很确定我有我的视图控制器他们应该在哪里，但加载html文件到表中没有发生。我在构建时没有收到任何错误，当我在模拟器中运行应用程序时，我只是在选项卡上获得空白表视图。

我不确定我需要提供哪些其他信息以帮助任何人 - 下面是相关文件的列表以及相关h/m文件中的代码。 （我不能发表图片尚未）

任何帮助或建议将不胜感激

Answer 1

你实现ToolboxViewController.m是不完整的。在你的代码都numberOfSectionsInTableView:和numberOfRowsInSection:正在返回0，这就是为什么没有什么是你的表出现。从我可以告诉你应用程序的描述中，他们应该分别返回1和你的articleList数组的长度。您还需要设置cellForRowAtIndexPath:中表格单元格的内容。

你可以做类似如下：

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 
    return 1; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    return [articleList length]; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"Cell"; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
    } 

    // here's where you set the content inside your table cell 
    cell.textLabel.text = [articleList objectAtIndex:[indexPath row]]; 

    return cell; 
} 

这应该足以让你开始。
