objective-c - SKPhysicsBody bodyWithPolygonFromPath内存泄漏

创建具有自定义形状的Sprite Kit物理实体时，我有一个奇怪的内存泄漏。这是我的实现的样子:

CGFloat offsetX = self.frame.size.width * self.anchorPoint.x;
CGFloat offsetY = self.frame.size.height * self.anchorPoint.y;

CGMutablePathRef path = CGPathCreateMutable();
CGPathMoveToPoint(path, NULL, 4 - offsetX, 3 - offsetY);
CGPathAddLineToPoint(path, NULL, 66 - offsetX, 3 - offsetY);
CGPathAddLineToPoint(path, NULL, 35 - offsetX, 57 - offsetY);
CGPathCloseSubpath(path);

self.physicsBody = [SKPhysicsBody bodyWithPolygonFromPath:path];

CGPathRelease(path);

一切都在SKSpriteNode方法内进行。在创建这样的主体之后，Instruments告诉我一些内存泄漏:

Leaked object:
  Malloc 32 Bytes
Size:
  32 Bytes
Responsible Library:
  PhysicsKit
Responsible Frame:
  std::__1::__split_buffer<PKPoint, std::__1::allocator<PKPoint>&>::__split_buffer(unsigned long, unsigned long, std::__1::allocator<PKPoint>&)

CGPathRelease(path);行是必需的-如果没有它，我会收到更多关于CGPath的内存泄漏，这是可以理解的。当我改用此实现(出于测试目的)时:

CGFloat radius = MAX(self.frame.size.width, self.frame.size.height) * 0.5f;
self.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:radius];

...一切正常，没有内存泄漏。我想知道这是Sprite Kit错误还是我做错了什么。

最佳答案

这是Sprite Kit中的错误。您将不得不等待修复。
