当您按下主页按钮时,SpriteKit应该清理并暂停所有计时器.
但是,我们发现如果您在显示活动SKView时单击主页按钮,则应用程序崩溃.即使该视图已被用户暂停,也会发生这种情况.
奇怪的是,如果你双击主页按钮并转到多任务视图,一切正常.
跟进注意：模拟器在两种情况下都能完美运行,不会发生崩溃
有没有人用SpriteKit看到这个问题？
你找到了原因/解决方案吗？
解决方法
我有同样的问题,我解决了它在应用程序移动到后台之前手动暂停ViewController中的根SKView：
- (void)viewDidLoad
{
[super viewDidLoad];
// Configure the view (already setup as SKView via storyboard)
SKView * skView = (SKView *)self.view;
// Create and configure the scene.
SKScene *scene = [Menu sceneWithSize:CGSizeMake(skView.bounds.size.height,skView.bounds.size.width)];
scene.scaleMode = SKScenescaleModeAspectFill;
// Present the scene.
[skView presentScene:scene];
[[NSNotificationCenter defaultCenter]
addobserver:self
selector:@selector(appWillEnterBackground)
name:UIApplicationWillResignActiveNotification
object:NULL];
}
- (void)appWillEnterBackground
{
SKView *skView = (SKView *)self.view;
skView.paused = YES;
[[NSNotificationCenter defaultCenter] removeObserver:self];
[[NSNotificationCenter defaultCenter]
addobserver:self
selector:@selector(appWillEnterForeground)
name:UIApplicationWillEnterForegroundNotification
object:NULL];
}
- (void)appWillEnterForeground
{
SKView * skView = (SKView *)self.view;
skView.paused = NO;
[[NSNotificationCenter defaultCenter] removeObserver:self];
[[NSNotificationCenter defaultCenter]
addobserver:self
selector:@selector(appWillEnterBackground)
name:UIApplicationWillResignActiveNotification
object:NULL];
}
