Sprite Kit crashes when launching an action / loading an asset only on iPad Air and iPad mini with retina

Question

I get crash reports from Retina mini and iPad Air devices, but not the iPhone 5S. This happens in SpriteKit when someone clicks on a sprite, which is supposed to then do a different display on the screen.

I cannot reproduce this on a device other than A7, so I wondered if anyone could take a look at the crash log below and tell me that a crash could happen?

This uses the code that I use to create a sprite that displays when another is found. Again, this does not happen on anything other than A7 devices, not on the iPhone. In addition, the same code fragment is used to do the same on other sprites and does not fall on them.

 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]; }]; }]; }]; } 

Thanks.

After some trial and error, I traced this to the presence of a sliced ​​image, where the top, bottom, left or right slice is 0. I would say that this is a bug in iOS. Try adding an extra complement to your image so that your fragments do not touch the edges.
