在哪种方法中,我将一个UIGestureRecognizer添加到我的SKScene.如何检测哪个节点被刷新？这似乎不起作用：
-(id)initWithSize:(CGSize)size {
if (self = [super initWithSize:size]) {
...
UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
recognizer.direction = UISwipeGestureRecognizerDirectionUp;
[[self view] addGestureRecognizer:recognizer];
}
return self;
}
解决方法
您可以在此方法中添加UISwipeGestureRecognizer：
- (void)didMoveToView:(SKView *)view
{
UISwipeGestureRecognizer *recognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe:)];
recognizer.direction = UISwipeGestureRecognizerDirectionUp;
[[self view] addGestureRecognizer:recognizer];
}
这就是您如何检测哪个SKNode被刷新：
- (void)handleSwipe:(UISwipeGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded)
{
CGPoint touchLocation = [sender locationInView:sender.view];
touchLocation = [self convertPointFromView:touchLocation];
SKSpriteNode *touchedNode = (SKSpriteNode *)[self nodeAtPoint:touchLocation];
NSLog(@"%@",touchedNode);
}
}
