ios - 从右向左滑动手指，反之亦然:-)

Question

我正在开发笑话应用程序，但我仍然缺少一个功能，即显示笑话文本视图的方式与在 Iphone 中显示照片的方式相同，并让用户从右向左滑动手指，反之亦然：

有没有人有一个例子或知道一个？

Answer 1

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中

 [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.
  }
}

Answer 2

UIPageViewController如果我理解您的要求，您正在寻找。

设置 aUIPageViewController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，就可以了！

可以从UIPageViewController的类引用中引用委托方法。
