将滑动手势识别器添加到 DetailViewContoller

Question

我有一个简单的 xcode 项目，它是由“主从应用程序”模板制作的，适用于 iPad。当设备处于纵向时，主视图被隐藏，当您在详细视图上向右滑动时，主视图将显示。现在，我想将右滑动手势识别器添加到详细视图中，如下所示：

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

    UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandler)];
    [self.view addGestureRecognizer:gestureRecognizer];
}

-(void)swipeHandler{
    NSLog(@"SWIPE");
}

但是这段代码导致当我在详细视图上滑动时，“SWIPE”日志出现在控制台中，但主视图没有出现。

如何将向右滑动手势识别器添加到详细视图，这样它就不会阻止主视图显示并且我的识别器处理程序可以工作？

提前致谢。

编辑。我希望我的右滑动识别器处理程序与这个内置的同时工作，它显示主视图，但下面的代码不是这种特定情况的解决方案：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{

    return YES;
}

Answer 1

您应该设置滑动的方向以添加正确的滑动

UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandler:)];
    [gestureRecognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
    [self.view addGestureRecognizer:gestureRecognizer];

你的滑动处理程序可能看起来像

-(void)swipeHandler:(UISwipeGestureRecognizer *)recognizer {
    NSLog(@"Swipe received.");
}

- (void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];

    UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeRecognizer:)];
    recognizer.direction = UISwipeGestureRecognizerDirectionRight;
    recognizer.delegate = self;
    [self.view addGestureRecognizer:recognizer];
}

- (void)swipeRecognizer:(UISwipeGestureRecognizer *)sender {
    if (sender.direction == UISwipeGestureRecognizerDirectionRight){
        [UIView animateWithDuration:0.3 animations:^{
            CGPoint Position = CGPointMake(self.view.frame.origin.x + 100.0, self.view.frame.origin.y);
            self.view.frame = CGRectMake(Position.x , Position.y , self.view.frame.size.width, self.view.frame.size.height);
            [self.navigationController popViewControllerAnimated:YES];
        }];
    }
}

Answer 3

试试这个

//向右滑动

UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandlerRight:)];
[gestureRecognizer setDirection:(UISwipeGestureRecognizerDirectionRight)];
[self.view addGestureRecognizer:gestureRecognizer];

//向左滑动

UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHandlerLeft:)];
[gestureRecognizer setDirection:(UISwipeGestureRecognizerDirectionLeft)];
[self.view addGestureRecognizer:gestureRecognizer];

调用方法

-(void)swipeHandlerRight:(id)sender
{
    //Your ViewController
}

-(void)swipeHandlerLeft:(id)sender
{
 //Your ViewController
}

这行得通。它从 navigationController 推送视图控制器。

- (void)viewDidLoad
{
     [super viewDidLoad];
     // Do any additional setup after loading the view, typically from a nib.
     UISwipeGestureRecognizer *gestureRecognizer = [[UISwipeGestureRecognizer           alloc] initWithTarget:self  action:@selector(swipeHandler:)];
     [self.view addGestureRecognizer:gestureRecognizer];
}

-(IBAction)swipeHandler:(UISwipeGestureRecognizer *)sender
{
      NSLog(@"SWIPE");
      UIViewController *tb = [[DetailViewController alloc] init];
      tb = [self.storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];
      [self.navigationController pushViewController: tb animated:YES];
}

然后一定要转到故事板（或者您也可以手动执行此操作） - 单击详细视图控制器并为视图控制器提供标识：DetailViewController

第 1 步：在 viewDidLoad() 方法中添加滑动手势。

override func viewDidLoad() {
    super.viewDidLoad()

    let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(handleGesture))
    swipeLeft.direction = .left
    self.view.addGestureRecognizer(swipeLeft)

    let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(handleGesture))
    swipeRight.direction = .right
    self.view.addGestureRecognizer(swipeRight)


}

第 2 步：检查 handleGesture() 方法中的手势检测

@objc func handleGesture(gesture: UISwipeGestureRecognizer) -> Void {
    if gesture.direction == UISwipeGestureRecognizerDirection.right {
        print("Swipe Right")
    }
    else if gesture.direction == UISwipeGestureRecognizerDirection.left {
        print("Swipe Left")
    }

}
