我的游戏中有一层。在游戏结束时，我想向用户显示一个 UIAlertView 以重新启动或退出游戏。但它不起作用。我还获得了委托 UIAlertViewDelegate 进行分层。

任何解决方案？

我的代码如下，

-(void)gameFinished{
    [[UIApplication sharedApplication] setIdleTimerDisabled:NO];

    [self unschedule:@selector(checkForCollision)];
    [self unschedule:@selector(dropObject)];
    [self stopBackgroundMusic];

    [self startNewForegroundMusic:@"GameOver" ofType:@"caf"];
    [self playForegroundMusic];

    [[Director sharedDirector] pause];
    UIAlertView *view=[[UIAlertView alloc] initWithTitle:@"Game Finished" message:@"Want to play again?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes"];
    [view show];
    [view release];
}

您的代码会崩溃，还是只是不显示？

您确实在行中有一个小错误

[[UIAlertView alloc] initWithTitle:@"Game Finished"
                     message:@"Want to play again?"
                     delegate:self cancelButtonTitle:@"No"
                     otherButtonTitles:@"Yes"]

这应该是

[[UIAlertView alloc] initWithTitle:@"Game Finished"
                     message:@"Want to play again?"
                     delegate:self cancelButtonTitle:@"No"
                     otherButtonTitles:@"Yes", Nil]

注意：最后一个参数是可变参数，因此应该以 Nil 终止。

尝试在导演暂停之前显示警报视图，它可能会起作用..
