将滑动手势识别器添加到 DetailViewContoller

【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;
【问题讨论】:
【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];
];
【讨论】:
【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
【讨论】:
【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")
