Question

我正在处理笑话的应用程序，我还有一个功能仍然缺失，它显示了笑话文本视图，以同样的方式在Iphone中逐个显示照片，并让用户从右向左滑动手指，或者反之亦然：

有没有人有例子或知道一个？

Answer 1

如果我理解你的要求，你正在寻找UIPageViewController。

设置UIPageViewController非常简单。

UIPageViewController *pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];

然后只需设置委托，并创建相应的委托方法，你就完成了！

委托方法可以从UIPageViewController的{{3}}引用。

祝你好运！欢迎来到Stack Overflow！

执行此操作以检测滑动：

UISwipeGestureRecognizer *swipeLeftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
    swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;


UISwipeGestureRecognizer *swipeRightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
    swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionRight;

//将其添加到您想要的视图

 [self.view addGestureRecognizer:swipeLeftRecognizer];
 [self.view addGestureRecognizer:swipeRightRecognizer];

//处理程序代码：

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
     //do something when swiped left.
}
else  if (recognizer.direction == UISwipeGestureRecognizerDirectionRight) 
  {
   //do something when swiped right.
  }
}

从右向左滑动手指，反之亦然:-)
