objective-c - Sprite Kit - iOS 7.1 更新后对象因缩放而发生碰撞

Question

没有问题，但在 iOS 7.1 更新后，对象正在碰撞 2pipes 的间隙。之前有人说，可能是因为'yScale'，但我找不到解决方案。

一些代码；

  Pipe *pipe = [[Pipe alloc] initWithImageNamed:pipeImageName];
  [pipe setCenterRect:CGRectMake(26.0/kPipeWidth, 26.0/kPipeWidth, 4.0/kPipeWidth, 4.0/kPipeWidth)];
  [pipe setYScale:height/pipe.size.height];
  [pipe setPosition:CGPointMake(320+(pipe.size.width/2), abs(pipeYOffset + (pipe.size.height/2)))];

  pipe.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:pipe.size];
  [pipe.physicsBody setAffectedByGravity:NO];
  [pipe.physicsBody setDynamic:NO];

任何帮助将不胜感激。谢谢!

  Pipe *pipe = [[Pipe alloc] initWithImageNamed:pipeImageName];
  [pipe setCenterRect:CGRectMake(26.0/kPipeWidth, 26.0/kPipeWidth, 4.0/kPipeWidth, 4.0/kPipeWidth)];

//set the physicsBody before X/Yscale
  pipe.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:pipe.size];

  [pipe setYScale:height/pipe.size.height];
  [pipe setPosition:CGPointMake(320+(pipe.size.width/2), abs(pipeYOffset + (pipe.size.height/2)))];

  [pipe.physicsBody setAffectedByGravity:NO];
  [pipe.physicsBody setDynamic:NO];

这可能对您有所帮助。 我认为这是 ios7.1 中的错误。
