Ios 手势滑动-情节提要序列

一直在阅读手势滑动以及如何根据方向打开或关闭UIView。我只是想到了一个我没能解决的问题。我可以识别触摸事件，即上、下、左、右。然而，当我尝试切换到另一个屏幕（在故事板中）时，我收到一个非常模糊的错误，我不知道从哪里开始。我已经看到其他应用程序这么清楚地做到了这一点，只是没有找到正确的图坦卡蒙或例子。下面是代码，如果有人有想法的话

- (void)viewDidLoad

{ UISweepGestureRecognizer*swipeUp=[[UISweepGestureRecognizer alloc]initWithTarget:self action:@selector（didSwipe:）]； swipeUp.numberoftouchsrequired=1； swipeUp.direction=uiswipgesturerecognizerDirectionUp； [self.view addgesturecognizer:swipeUp]

UISwipeGestureRecognizer *swipeDown = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(didSwipe:)];
swipeDown.numberOfTouchesRequired = 1;
swipeDown.direction = UISwipeGestureRecognizerDirectionDown;
[self.view addGestureRecognizer:swipeDown];

UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(didSwipe:)];
swipeLeft.numberOfTouchesRequired = 1;
swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
[self.view addGestureRecognizer:swipeLeft];

UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(didSwipe:)];
swipeRight.numberOfTouchesRequired = 1;
swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
[self.view addGestureRecognizer:swipeRight];

[super viewDidLoad];
// Do any additional setup after loading the view.

//[self.view removeGestureRecognizer:swipeUp]； //[self.view removeGestureRecognizer:swipeDown]； //[self.view RemovegestureRecognitor:swipeLeft]； //[self.view removeGestureRecognizer:swipeRight]； }

你能显示错误吗？顺便说一句，你为什么不使用一个简单的表演序列呢？这是另一个故事板吗？嗨，Shannoga，是的，我在键入这条消息时试图重现错误。正常的segue工作正常，但当你转到上一个屏幕时，它会中止。我认为这与确定其来源有关，即上一屏幕、下一屏幕场景。我将在可以再次执行错误时尽快发布错误。收到错误：线程1:EXC_BAD_ACCESS（代码=2，地址=0x100）。当您将手指指向正确方向，然后返回时，会发生这种情况。我想我可能需要为我想要操纵的每个视图创建一个新的.h/.m类，然后告诉视图它来自何处以及它将要去何处。我想…收到错误：**由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“无效参数不满足：[标识符长度]>0”我看到的一个常见特征是，如果任何方向的手势超过3次，则会失败。我认为它需要以某种方式释放…你能在检测到任何刷卡后立即尝试移除手势识别器吗？
