【中文标题】将滑动手势识别器添加到 DetailViewContoller【英文标题】:Adding swipe gesture recognizer to DetailViewContoller 【发布时间】:2013-03-01 19:48:23 【问题描述】:

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;

【参考方案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.");

我认为向右滑动实际上是默认方向,这不是问题所在 是的,我做到了。我的识别器工作得很好,但是这个内置的不能再工作了,这就是问题所在。 您是否正确设置了代理?对于gestureRecognizer?当您实现委托方法时 是的,我已经检查过了,但我仍然只能让我的手势识别器工作,而 master vew 没有出现。 试试这个属性可能会成功...self.splitViewController.presentsWithGesture = YES; //for showing the maset view【参考方案2】:
- (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];
        ];

【参考方案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

【参考方案4】:

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

我不确定如何处理您的回答。关于滑动方向的知识是否可以解决我的问题? 我真的需要这两者:我的和内置的 regonizers 在同一个视图上工作,即细节视图。 您想要自己进行滑动处理并禁用主视图的呈现,还是想要对正在呈现的主视图做出反应? @MartinUllrich 我想做自己的滑动处理,但我不想停止主视图呈现。问题是,当我以某种方式添加自己的滑动处理时,它会停止呈现主视图 @darko_5 你试过我上面的想法了吗?在我找到在 xcode 上尝试的解决方案后,我编辑了我的原始帖子。它对你有用吗?您找到其他解决方案了吗?【参考方案5】:

斯威夫特 4.0

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")
