添加滑动手势以在详细视图中显示下一个项目 - 修订 [英] Add Swipe Gesture to display the next Item in the Detailed View - Revised

问题描述

这是我之前的问题 添加滑动手势以在详细视图中显示下一个项目

我以前问过这个问题，但不知道如何根据我的进度更新它.

I have asked this question before but not sure how to update it with my progress.

我遵循了一些建议，但现在我又被卡住了.

I followed some suggestions but now I am stuck again.

我现在想向目标视图控制器添加一个滑动手势，这样我就可以进入下一篇文章而无需返回主页.我添加了以下内容来设置手势以及加载数组中的项目的函数.

I want to now add a swipe gesture to the destination view controller so that I can get to the next article without having to go back to the main page. I have added the following to set up the gesture as well as a function to load the items in the array.

所有这些数据都通过 segue 传递给了 ViewController

All this data has been passed to the ViewController via segue

-(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];     
}

现在我卡住了，不知道如何前进.请指教.

Now I am stuck and have no clue on how to move forward. Please advise.

推荐答案

你永远不会改变你传递的索引:

You aren't ever changing the index you are passing with :

    [self loadArticleForIndex:_articleListsports.count];

所以这个例程将始终显示相同的文章:

So this routine will always show the same article:

    - (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，并在浏览文章时增加索引.

and hence nothing will change. You need to keep some sort of index around and increment it as you swipe through the articles.

    [self loadArticleForIndex:currentIndex++];
