Question

这是我尝试配置的.m的一部分：这是我的UIAlertView：

NSString *message = [NSString stringWithFormat:@"Score %d", _score];
UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Game Over"
                                                     message:message
                                                    delegate:nil
                                           cancelButtonTitle:@"Play Again"
                                           otherButtonTitles:nil];
[av show];

我正在尝试制作上面的UIAlertView，所以当我点击Play Again时，它会这样做：

[self runAction:[SKAction sequence:@[[SKAction repeatAction:[SKAction sequence:@[[SKAction runBlock:^{

        }], [SKAction waitForDuration:0.05],  [SKAction waitForDuration:0.05]]] count:4], [SKAction runBlock:^{
            _canRestart = YES;
        }]]]];

这是我的.h：

#import <SpriteKit/SpriteKit.h>

@interface MyScene : SKScene

@end

我已经添加了vborra所说的内容，我仍然使用未声明的标识符'alertView'消息。在.h中声明，这是我正在尝试配置的.m中的代码

（void）alertView：UIAlertView *）alertView clickedButtonAtIndex：（NSInteger）buttonIndex [self runAction：[SKAction序列：@ [[SKAction repeatAction：[SKAction sequence：@ [[SKAction runBlock：^ {
```
    }], [SKAction waitForDuration:0.05],  [SKAction waitForDuration:0.05]]] count:4], [SKAction runBlock:^{
        _canRestart = YES;
    }]]]];
```

查看UIAlertViewDelegate，每当按下提醒时都会调用它：https://developer.apple.com/library/ios/documentation/uikit/reference/UIAlertViewDelegate_Protocol/UIAlertViewDelegate/UIAlertViewDelegate.html

UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Game Over" message:message delegate:self cancelButtonTitle:@"Play Again" otherButtonTitles:nil];

然后在你的委托方法（- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex）中：

[self runAction:[SKAction sequence:@[[SKAction repeatAction:[SKAction sequence:@[[SKAction runBlock:^{

    }], [SKAction waitForDuration:0.05],  [SKAction waitForDuration:0.05]]] count:4], [SKAction runBlock:^{
        _canRestart = YES;
    }]]]];

然后按下“确定”按钮后游戏将重新启动。
