仅在配备 Retina 的 iPad Air 和 iPad mini 上运行操作/加载资产时 Sprite Kit 崩溃 [英] Sprite Kit crash when running an action/loading an asset on only iPad Air and iPad mini with Retina
问题描述
我收到了来自 Retina mini 和 iPad Air 设备的崩溃报告，但不是来自 iPhone 5S.它发生在 SpriteKit 中，当有人点击一个应该让另一个精灵出现在屏幕上的精灵时.
I'm getting crash reports which are coming from retina mini and iPad Air devices, but not iPhone 5S. It occurs in SpriteKit when someone taps on a sprite which is supposed to then make another show up on screen.
我无法在非 A7 设备上重现此问题，所以想知道是否有人可以查看下面的崩溃日志并告诉我崩溃可能是由什么引起的?
I'm not able to reproduce this on a non-A7 device so wondered if anyone can take a look at the crash log below and let me know what the crash may be caused by?

这是我用来创建在点击另一个时显示的精灵的代码.同样，这不会发生在 A7 设备上，而不是在 iPhone 上.此外，这个相同的代码片段用于在其他精灵上执行完全相同的操作，并且不会在这些精灵上崩溃.
Here's the code I use to create the sprite that's being displayed when the other is tapped on. Again this doesn't happen on anything but A7 devices and not on iPhones. Additionally this same code snippet is used to do the exact same thing on other sprites and does not crash on those.
if ([touchedSprite.name isEqualToString:@"Sad"]) {
// Create the crop node
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
cropNode.position = CGPointMake(touchedSprite.position.x - 120, CGRectGetMinY(self.view.frame));
} else
cropNode.position = CGPointMake(touchedSprite.position.x - 120 * IPHONERATIO, CGRectGetMinY(self.view.frame) - 20);
SKSpriteNode *sadSprite = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:@"SadSprite"]];
[sadSprite setName:@"sadSprite"];
[cropNode addChild:sadSprite];
sadSprite.position = CGPointMake(sadSprite.position.x, sadSprite.position.y + sadSprite.size.height / 2);
SKSpriteNode *maskedImage = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImageNamed:@"SadSpriteMask"]];
[cropNode setMaskNode:maskedImage];
[self addChild:cropNode];
NSArray *slurpSounds = @[@"sadSprite01.caf", @"sadSprite02.caf", @"sadSprite03.caf"];
// Keep the sadSprite in the same position in relation to the egg
[sadSprite runAction:[SKAction moveByX:0 y:-sadSprite.size.height duration:0.6]];
// Move the sadSprite into position
[cropNode runAction:[SKAction moveByX:0 y:sadSprite.size.height duration:0.6] completion:^{
[cropNode runAction:[SKAction playSoundFileNamed:slurpSounds[self.toolSoundNumber] waitForCompletion:YES] completion:^{
[sadSprite runAction:[SKAction moveByX:0 y:sadSprite.size.height duration:0.6] completion:^{
[sadSprite removeFromParent];
}];
[cropNode runAction:[SKAction moveByX:0 y:-sadSprite.size.height duration:0.6] completion:^{
[cropNode removeFromParent];
}];
}];
}];
}
谢谢.
推荐答案
经过反复试验，我找到了一个切片图像，其中顶部、底部、左侧或右侧切片的大小为 0.我会这样说是iOS上的一个错误.尝试为您的图像添加更多填充，这样您的切片就不会接触到边缘.
After some trial and error I tracked this down to having a sliced image where the top, bottom, left or right slice has size 0. I'd say this is a bug on iOS. Try adding more padding to your image so that your slices don't touch the edges.
