Question

我遇到了一个非常奇怪的错误导致我的应用崩溃。我创建了一个名为heroSpriteNode的自定义SKSpriteNode。这是我的初始化：

 (id) init
{
 if (self = [super init])
{
    [self loadAnimations];
    SKTexture *temp = self.gorillaStandingFrames[0];
    self = [heroSpriteNode spriteNodeWithTexture:temp];
    [self setUpHeroDetails];
}
return self;
}

尝试在＆＃34; self＆＃34;上运行操作时发生错误自定义SkSpriteNode，如下所示：

-(void)jump
{

NSLog(@"Jump Tap!");

if(self.isOnTheGround)
{
    self.physicsBody.velocity = CGVectorMake(0, 0);
    self.physicsBody.angularVelocity = 0;
    self.timedJump=NO;
    [self.physicsBody applyImpulse:CGVectorMake(0, 350)];
    [self removeActionForKey:@"walkingInPlaceBear"];
    [self jumpingGorilla2]; // HERE IS THE ERROR
    self.isOnTheGround=NO;
    self.isRunning=NO;
    self.isStanding=NO;
    self.jumpFixTimer = [NSTimer scheduledTimerWithTimeInterval:0.4 target:self selector:@selector(flipTimedJumpBoolean) userInfo:nil repeats:NO];

}

}

我知道这个动画（以及我运行的其他动画）是个问题，因为当我注释掉那条线时游戏运行正常。

以下是我如何加载纹理和创建动作：

-(void)loadJumpAnimation2
{
NSMutableArray *jumpFrames = [NSMutableArray array];
SKTextureAtlas *gorillaAnimatedAtlas = [SKTextureAtlas atlasNamed:@"mainCharJump"];
int numImages = gorillaAnimatedAtlas.textureNames.count;
for (int i=2; i <= numImages; i++) {
    NSString *textureName = [NSString stringWithFormat:@"j%d", i];
    SKTexture *temp = [gorillaAnimatedAtlas textureNamed:textureName];
    [jumpFrames addObject:temp];
}
self.gorillaFlyingJump = jumpFrames;

}


-(void)jumpingGorilla2
{

[self runAction:[SKAction repeatActionForever:
                         [SKAction animateWithTextures:self.gorillaFlyingJump
                                          timePerFrame:0.25f
                                                resize:NO
                                               restore:YES]]       withKey:@"jump"];

return;
}

当它崩溃时，记录器中没有崩溃报告，只有Xcode中的弹出消息类型为：9 SIGKILL。看起来这可能是与动画帧存储方式有关的内存问题？动画在标准的SkSpriteNode上运行良好，然后在将大部分代码重构为自定义SkSpriteNode之后，我再也无法应用动画了。有任何想法吗？谢谢。

更新：

我已经创建了另一个类来尝试隔离我遇到的问题，我将在下面发布评论代码。

这是我创建的整个测试类：

#import "heroTestNode.h"

@implementation heroTestNode


- (id) init
{
if (self = [super init])
{
    [self loadAnimations];
    SKTexture *temp = self.gorillaWalkingFrames[0];
    self = [heroTestNode spriteNodeWithTexture:temp];
}
return self;
}



-(void)loadAnimations
{

 NSMutableArray *walkFrames = [NSMutableArray array];
 SKTextureAtlas *gorillaAnimatedAtlas = [SKTextureAtlas     atlasNamed:@"mainCharRun2"];


int numImages = gorillaAnimatedAtlas.textureNames.count;
NSLog(@"Here are how many animation frames: %d", numImages);

for (int i=1; i <= numImages; i++) {
    NSString *textureName = [NSString stringWithFormat:@"r%d", i];
    SKTexture *temp = [gorillaAnimatedAtlas textureNamed:textureName];
    [walkFrames addObject:temp];
}
self.gorillaWalkingFrames = walkFrames;
}

-(void)walkingGorilla // running this is causing the SIGKILL 9 crash
{

[self runAction:[SKAction repeatActionForever:
                 [SKAction animateWithTextures:self.gorillaWalkingFrames
                                  timePerFrame:0.1
                                        resize:NO
                                       restore:YES]]   withKey:@"test"];
return;
}



@end

这是界面：

#import <SpriteKit/SpriteKit.h>

@interface heroTestNode : SKSpriteNode
@property NSMutableArray *gorillaWalkingFrames;
-(void)walkingGorilla;

@end

最后，这是我如何实例化它：

heroTestNode *test = [[heroTestNode alloc] init];
test.position =  CGPointMake((self.frame.size.width/2)+30,self.frame.size.height/3);
[self addChild:test];
[test walkingGorilla]; // this is causing the SIGKILL 9 crash

这导致它冻结＆＃34;压缩＆＃34;我的iPad左下角的视图并没有反应。我不知道会造成什么。

在自定义SKSpriteNode上运行动画时，游戏与SIGKILL崩溃
