Question

这是我之前的问题Add Swipe Gesture to display the next Item in the Detailed View

我之前已经问过这个问题，但不知道如何根据我的进度更新它。

我遵循了一些建议，但现在又被卡住了。

我现在想要向目标视图控制器添加一个滑动手势，这样我就可以转到下一篇文章而无需返回主页面。我添加了以下内容来设置手势以及加载数组中项目的功能。

所有这些数据都已通过segue传递给ViewController

-(IBAction)swipeHandler:(UISwipeGestureRecognizer *)gesture{
{
    [self loadArticleForIndex:_articleListsports.count];
    NSLog(@"SWIPE");
    NSLog(@"Found %d character(s).", [_articleListsports count]);
}

- (void)loadArticleForIndex:(int)index
{
    //draw ur article or load your webview.

    if(index>0 && index <[_articleListsports count])
    {
        //self.targetURL  = selectedCell.targetURL;
        self.sdesc = self.sportsdescription.text;
        self.stitle = self.sportstitle.text;
        self.simage = self.sportsimage.image;
        self.scat = self.sportscategory.text;
        self.sdate = self.sportsdate.text;
    }
}


- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    UISwipeGestureRecognizer *recognizer;
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandler:)];
    [recognizer setDirection:UISwipeGestureRecognizerDirectionLeft];
    [[self view] addGestureRecognizer:recognizer];

    NSString *fileName = [NSString stringWithFormat:@"%@/sports.rss", [SPORTSUtil getDocumentRoot]];
    _articleListsports = [NSArray arrayWithContentsOfFile:fileName];     
}

现在我陷入困境，并且不知道如何前进。请指教。

您永远不会更改传递的索引：

    [self loadArticleForIndex:_articleListsports.count];

因此，此例程将始终显示相同的文章：

    - (void)loadArticleForIndex:(int)index
   {
        //draw ur article or load your webview.

        if(index>0 && index <[_articleListsports count])
        {
            //self.targetURL  = selectedCell.targetURL;
            self.sdesc = self.sportsdescription.text;
            self.stitle = self.sportstitle.text;
            self.simage = self.sportsimage.image;
            self.scat = self.sportscategory.text;
            self.sdate = self.sportsdate.text;
        }
    }

因此什么都不会改变。您需要保留某种索引并在浏览文章时递增它。

    [self loadArticleForIndex:currentIndex++];
