如何在 iPhone 的 Cocos2d 层上显示 UIAlertView？

发布于 2024-08-15 04:56:26 字数 716 浏览 3 评论 0原文

我的游戏中有一个层面。游戏结束时，我想向用户显示用于重新启动或退出游戏的 UIAlertView。但它不起作用。我还获得了委托 UIAlertViewDelegate 到图层。

有什么解决方案吗？

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];
}

I have a layer in my game. At finishing of game I want to show user an UIAlertView for restarting or quitting the game. But it is not working. I am also given the delegate UIAlertViewDelegate to layer.

Any Solutions?

My Code follows,

-(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];
}

您的代码是否崩溃，或者只是不显示？

您在这行中确实有一个小错误，

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

应该

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

注意：最后一个参数是变量参数，因此应该以 Nil 终止。

Does your code crash, or does it just not display?

You do have a slight error in the line

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

This should be

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

note: the last parameter is variable argument, and thus should be Nil terminated.
