iphone - 我正在尝试在自定义单元格中显示 xml 数据，但它正在工作，并且只显示一个数据

Question

- (void)viewDidLoad
    {
        NSURL *url=[[NSURL alloc]initWithString:@"http://avweatherforecasts.com/services/iphoneservice.php"];    
        DaTa=[[NSData alloc]initWithContentsOfURL:url];    
        NSLog(@"data----%@",DaTa);
        Xmlpaeser=[[NSXMLParser alloc]initWithData:DaTa];    
        Xmlpaeser.delegate=self;    
        [Xmlpaeser parse];
        [Xmlpaeser release];

        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
    }

试试这个......也许它会帮助你......

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

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
      return [CommentsGetArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) 
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] ;
        //[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;



        commentsTextView = [[UITextView alloc]initWithFrame:CGRectMake(90, 4, 190, 50)];
        commentsTextView.delegate = self;
        commentsTextView.tag = 101;
        commentsTextView.textAlignment = UITextAlignmentLeft;

        [commentsTextView setScrollEnabled:YES];

        commentsTextView.backgroundColor =[UIColor clearColor];
        commentsTextView.font = [UIFont fontWithName:@"Arial" size:12.0];
        commentsTextView.textColor =[UIColor blackColor];
        commentsTextView.editable = NO;
        [cell addSubview:commentsTextView];



    }



     commentsTextView = (UITextView *)[cell viewWithTag:101];
    commentsTextView.text = [[CommentsGetArray objectAtIndex:indexPath.row]objectForKey:@"comment"];


    return cell;

}
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{

    return 70;
}

您可以将其用作标签而不是 uitextView，并且您可以创建更多文本视图或标签来显示您的数据，但请记住更改它们的框架。
