奇怪的EXC_BAD_ACCESS SpriteKit removeSubsprite崩溃 [英] Strange EXC_BAD_ACCESS SpriteKit removeSubsprite crash

问题描述

我是SpriteKit的新手，刚刚建立了我的第一场比赛.直到iOS 7.1一切都运转良好.现在，经过几次前进到一个新的水平并提出一个新的Scene之后，它崩溃了.我认为我的呈现方式不正确:

I am new to SpriteKit and just built my first game. Everything was working great until iOS 7.1. Now, after a few times of advancing to a new level and presenting a new Scene, it crashes. I don't think I am presenting it in an incorrect way:

ZSSMyScene *nextLevel = [[ZSSMyScene alloc] initWithSize:self.size level:self.level score:score];
[self.view presentScene:nextLevel];

我收到一个EXC_BAD_ACCESS错误，看起来好像是在removeSubsprite上发生的，但是我在代码的任何地方都找不到要删除子精灵的东西:

I get a EXC_BAD_ACCESS error, and it looks like it is happening on removeSubsprite, but I can't find anywhere in my code that I would be removing a subsprite:

不确定要提供什么其他信息，因为这只是我更新至iOS 7.1 SDK时似乎开始出现的晦涩错误.

Not sure what other info to provide as this is just an obscure error that seemed to start when I updated to iOS 7.1 SDK.

推荐答案

这似乎是一个错误，可能仅与SKShapeNodes有关.

This appears to be a bug, possibly only with SKShapeNodes.

我的解决方案是创建一个SKNode类别，并在我要删除的任何节点有子节点时调用此清理方法.

My solution was to create an SKNode category and call this cleanup method when any node i'm removing has children.

- (void)cleanUpChildrenAndRemove {
    for (SKNode *child in self.children) {
        [child cleanUpChildrenAndRemove];
    }
    [self removeFromParent];
}
