Question

我有一个数组，其中包含10个项目，即1,2,3,4,5,6,7,8,9,10。当我加载页面时，项目位于3.所以当用户向左滑动时，它将转到4并向右滑动它将转到2.我可能知道该怎么做吗？

newsID=[[NSMutableArray alloc]init];
[newsID addObject:@"1"];
[newsID addObject:@"2"];
[newsID addObject:@"3"];
[newsID addObject:@"4"];
[newsID addObject:@"5"];
[newsID addObject:@"6"];
[newsID addObject:@"7"];
[newsID addObject:@"8"];
[newsID addObject:@"9"];
[newsID addObject:@"10"];
UISwipeGestureRecognizer * swipeleft=
    [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeleft:)];
swipeleft.direction=UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:swipeleft];
UISwipeGestureRecognizer * swiperight=
    [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swiperight:)];
swiperight.direction=UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:swiperight];

试试这个。我正在使用一个UILabel并在滑动时更改它的文本。并使用一个int变量来跟踪滑动。

Answer 2

以下是处理滑动手势的简单示例。在这里，我正在拿一个UILabel并在滑动时更改它的文本。

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


    _lblText.text=@"3";
    _lblText.textAlignment=NSTextAlignmentCenter;


    UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleRightSwipe)];
    swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
    [self.view addGestureRecognizer:swipeRight];


    UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleLeftSwipe)];
    swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.view addGestureRecognizer:swipeLeft];

}

-(void)handleRightSwipe
{

    if ([_lblText.text intValue]>1)
    {
        _lblText.text=[NSString stringWithFormat:@"%d",[_lblText.text intValue]-1];
    }
    else
    {
        return;
    }
}

-(void)handleLeftSwipe
{

    if ([_lblText.text intValue]<10)
    {
        _lblText.text=[NSString stringWithFormat:@"%d",[_lblText.text intValue]+1];
    }
    else
    {
        return;
    }

}

向左和向右滑动以加载项目
