使用滑动手势进行视图导航

Question

如何使用滑动手势垂直切换视图？

Answer 1

我找到了答案.我发布的代码供您参考.谢谢 :-)

在 viewDidLoad

  UISwipeGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipedScreendown:)] autorelease];
  swipeGesture.numberOfTouchesRequired = 1;
  swipeGesture.direction = UISwipeGestureRecognizerDirectionDown;
  [m_pImageView addGestureRecognizer:swipeGesture];

现在

- (void)swipedScreendown:(UISwipeGestureRecognizer*) swipeGesture {
  m_pViewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
  CATransition *transition = [CATransition animation];
  transition.duration = 0.75;
  transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
  transition.type = kCATransitionPush;
  transition.subtype = kCATransitionFromBottom;
  transition.delegate = self;
  [self.view.layer addAnimation:transition forKey:nil];
  [self.view addSubview:PadViewController.view];
}

实现这个(didload)

//........towards right Gesture recogniser for swiping.....//
UISwipeGestureRecognizer *rightRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwipeHandle:)];
rightRecognizer.direction = UISwipeGestureRecognizerDirectionRight;
[rightRecognizer setNumberOfTouchesRequired:1];
[urView addGestureRecognizer:rightRecognizer];
[rightRecognizer release];

//........towards left Gesture recogniser for swiping.....//
UISwipeGestureRecognizer *leftRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwipeHandle:)];
leftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
[leftRecognizer setNumberOfTouchesRequired:1];
[urView addGestureRecognizer:leftRecognizer];
[leftRecognizer release];   

然后这个:

- (void)rightSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
{
//Do moving
}

- (void)leftSwipeHandle:(UISwipeGestureRecognizer*)gestureRecognizer 
{
// do moving
}

当然!只需将viewController设置为UIGestureRecognizerDelegate并声明UISwipeGestureRecognizer *swipeLeftRecognizer;(也保留并合成).然后,在实现中,设置识别器

    UIGestureRecognizer *recognizer;
    // RIGHT SWIPE
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self 
                                                           action:@selector(handleSwipeFrom:)];
    [self.view addGestureRecognizer:recognizer];
    [recognizer release];
    // LEFT SWIPE
    recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipeFrom:)];
    self.swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer;
swipeLeftRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.view addGestureRecognizer:swipeLeftRecognizer];
self.swipeLeftRecognizer = (UISwipeGestureRecognizer *)recognizer;
    [recognizer release];

然后使用该方法触发所需的操作

- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
    if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
        // load a different viewController
    } else {
        // load an even different viewController
    }
}

你在这里做的是特定于你的应用程序.您可以切换tabBar选择,跳过navigationController,以模态方式呈现不同的视图,或者只是在转换中执行简单的幻灯片.
