如何根據觸摸的位置獲得兩個完全相同的UISwipeGestureRecognizer以同時工作？

Question

在我目前的Sprite Kit項目中，我編寫了一個機制，我已經將UISwipeGestureRecognizer用於向左方向應用於兩個節點。當在屏幕的一側出現左側滑動時，其中一個節點移動，而在屏幕另一側出現左側滑動時，另一個節點移動。但是，我找不到一種方法使節點同時移動;儘管屏幕上位於不同的位置，但仍然無法識別2個左側滑動。同樣，我也爲用戶向右滑動時編寫了類似的機制。以下是我的代碼。我將不勝感激任何幫助。截至目前，只有一個節點可以在同一時間內刷卡，不能兩者都在一起，這是我想

-(void)didMoveToView:(SKView *)view { 
    UISwipeGestureRecognizer *leftSwipe1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(leftSwiped1:)]; 

[leftSwipe1 setDirection:UISwipeGestureRecognizerDirectionLeft]; 
[leftSwipe1 setNumberOfTouchesRequired:1]; 
[self.view addGestureRecognizer:leftSwipe1]; 

UISwipeGestureRecognizer *rightSwipe1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(rightSwiped1:)]; 

[rightSwipe1 setDirection:UISwipeGestureRecognizerDirectionRight]; 
[rightSwipe1 setNumberOfTouchesRequired:1]; 
[self.view addGestureRecognizer:rightSwipe1]; 

self.physicsWorld.gravity = CGVectorMake(0, -9.8); 
self.physicsWorld.contactDelegate = self; 
    } 
    -(void)rightSwiped1:(UIGestureRecognizer *)gestureRecognizer { 

CGPoint pt = [gestureRecognizer locationInView:self.view]; 
if(pt.x < (self.view.bounds.size.width/2)) 
{ 
    SKNode *person1 = [self childNodeWithName:@"person1"]; 
    SKAction *moveRight = [SKAction moveTo:CGPointMake(CGRectGetMidX(self.frame) - 80, CGRectGetMidY(self.frame) + 200) duration:0.2f]; 
    [person1 runAction:moveRight]; 
} else if (pt.x > (self.view.bounds.size.width/2)) { 

    SKNode *person2 = [self childNodeWithName:@"person2"]; 
    SKAction *moveRight2 = [SKAction moveTo:CGPointMake(CGRectGetMidX(self.frame) + 400, CGRectGetMidY(self.frame) + 200) duration:0.2f]; 
    [person2 runAction:moveRight2]; 
} 


    } 
    -(void)leftSwiped1:(UIGestureRecognizer *)gestureRecognizer { 
CGPoint pt = [gestureRecognizer locationInView:self.view]; 
if(pt.x < (self.view.bounds.size.width/2)) 
{ 
    SKNode *person1 = [self childNodeWithName:@"person1"]; 
    SKAction *moveLeft = [SKAction moveTo:CGPointMake(CGRectGetMidX(self.frame) - 400, CGRectGetMidY(self.frame) + 200) duration:0.2f]; 
    [person1 runAction:moveLeft]; 
} else if (pt.x > (self.view.bounds.size.width/2)) { 

    SKNode *person2 = [self childNodeWithName:@"person2"]; 
SKAction *moveLeft2 = [SKAction moveTo:CGPointMake(CGRectGetMidX(self.frame) + 80, CGRectGetMidY(self.frame) + 200) duration:0.2f]; 
[person2 runAction:moveLeft2]; 
} 
    } 

Answer 1

嘗試實施這一方法是什麼：

- gestureRecognizer:shouldRecognizerSimultaneouslyWithGestureRecognizer: 

它會阻止你的手勢之一阻止對方。

另外，請確保將您當前的ViewController（此方法的實現將設置爲）作爲您的兩個UIGestureRecognizers的委託，以便實際調用此方法。

我希望這會有所幫助。祝你好運！

Answer 2

這是應該幫助你

首先，我們應該創建類，實現UIGestureRecognizerDelegate協議：

@interface TestGestureDelegate：NSObject的

@implementation TestGestureDelegate

• （ BOOL）gestureRecognizerShouldBegin：（UIGestureRecognizer *）gestureRecognizer { 返回YES; }

• （BOOL）gestureRecognizer：（UIGestureRecognizer *）gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer：（UIGestureRecognizer *）otherGestureRecognizer { 返回YES; }

• （BOOL）gestureRecognizer：（UIGestureRecognizer *）gestureRecognizer shouldReceiveTouch：（UITouch *）touch { return YES; }

而且這是很好的來源瞭解，Gesture
