Question

我的代码：

-(SKSpriteNode*) pauseButton
{
    SKSpriteNode* pauseButton = [SKSpriteNode spriteNodeWithImageNamed:@"pausebutton"];

    pauseButton.position = CGPointMake(CGRectGetMaxX(self.frame) -30,CGRectGetMaxY(self.frame) - 30);
    pauseButton.anchorPoint = CGPointMake(1.0, 1.0);
    pauseButton.name = @"pauseButton";
    pauseButton.zPosition = 160;

    return pauseButton;


}


-(SKSpriteNode*) playButton
{
    SKSpriteNode* playButton = [SKSpriteNode spriteNodeWithImageNamed:@"playbutton"];

    playButton.position = CGPointMake(CGRectGetMaxX(self.frame)- 30, CGRectGetMaxY(self.frame) - 30);
    playButton.anchorPoint = CGPointMake(1.0, 1.0);
    playButton.name = @"playButton";
    playButton.zPosition = -10;

    return playButton;


}

在touchesBegan：

    SKSpriteNode *pauseButton = (SKSpriteNode*)[self childNodeWithName:@"pauseButton"];
        CGPoint location = [touch locationInNode:self];


        if (!(gameIsOver))
        {

            if([pauseButton containsPoint:location])
            {
                if (self.scene.view.paused==YES)
                {

                    [myTimer start];

                    pauseButton.zPosition = 160;
                    [self childNodeWithName:@"playButton"].zPosition = -10;
                    self.scene.view.paused = NO;

                }
                else if (self.scene.view.paused ==NO)
                {

                    pauseButton.zPosition = -10;
                    [self childNodeWithName:@"playButton"].zPosition = 160;

                    [myTimer pause];
                    [self performSelector:@selector(pauseGame) withObject:Nil afterDelay:0.01];
                }
            }


-(void) pauseGame

{

   self.scene.view.paused = YES;



}

我的问题：

我不想使用：[self performSelector:@selector(pauseGame) withObject:Nil afterDelay:0.01];因为它不准确。我想在有人点击暂停按钮后立即设置self.scene.view.paused = YES;。但是，不设置延迟不会让暂停按钮改变播放。有没有办法解决这个问题。
有时，我的暂停按钮不会改变播放。我不知道为什么。这很少见。

任何帮助都将不胜感激。
