SKAction上的EXEC_BAD_ACCESS

Question

我正在開發Spritekit游戲。

當我觸摸節點嘗試運行操作時，我收到EXEC_BAD_ACCESS異常

該功能觸手可及

    -(void)selectNodeForTouch:(CGPoint)location {
    SKNode *touchedNode = (SKNode *)[self nodeAtPoint:location];
    NSLog(@"touched : %@",touchedNode.name);

    if([[touchedNode name] isEqualToString:@"piece"]){
        Piece *piece = (Piece *)[self nodeAtPoint:location];
        if ([piece isRotated])
            [piece rotateToFront];
        else
            [piece rotateToBack];
    }
}

對象Piece方法rotateBack ：

    -(void)rotateToBack{
    SKAction *rotationToBack = [SKAction animateWithTextures:[self animationFrames] timePerFrame:0.11];
    [self runAction:rotationToBack withKey:@"rotation-to-back"];
    [self setRotated:YES];
};

[self animationFrames]是一個NSMutable數組，可通過以下方式轉換為NSArray

[self setAnimationFrames:[NSArray arrayWithArray:frames]];

最后的幀是一個包含一些SKTextures的NSMutableArray

執行過程在動畫執行時中斷。

在Piece類中

更改此行：

NSString *imageName = [NSString stringWithFormat:@"%@-1%@",[self baseImageName],imageResolution];

至

NSString *imageName = [NSString stringWithFormat:@"%@-1",[self baseImageName]];
