游戏结束时，uiimageview.image并不总是在变化

Question

嗨，我非常喜欢编码，并开始在Xcode中制作一个非常简单的游戏。游戏已经完成，但我确实遇到了一些问题。很少有时候在游戏结束时，pig.image不会改变，之前的动画甚至在[pig stopAnimation]之后仍然继续...继承游戏结束时的代码到图像应该改变的地方...... / p>

-(void)gameover1{


[jetpacksound stop];

[self hitsound];

[pig stopAnimating];

[movementtimer invalidate];

if (score > highscorenumber) {
    highscorenumber = score;
    [[NSUserDefaults standardUserDefaults] setInteger:highscorenumber forKey:@"highscoresaved"];
}
else{
    highscore.text = [NSString stringWithFormat:@"Try Harder Next Time"];
}

movementtimer = [NSTimer scheduledTimerWithTimeInterval:.035 target:self         selector:@selector(gameover1movement) userInfo:nil repeats:YES];



bam.hidden = NO;
flash.hidden = NO;

background1.hidden = YES;
background2.hidden = YES;
background3.hidden = YES;

pauseg.hidden = YES;
scorelabel.hidden = YES;

fork1.hidden = YES;
